Augmentation intestinal cystoplasty is usually the preferred method. However, this is complicated by mucus production, recurrent infection and cystolithiasis. In this report, the authors present a unique case of laparoscopically-assisted ureterocystoplasty and describe the operative technique and its advantages.
A 68-year-old female with a contracted urinary bladder and a solitary functioning kidney was diverted with a percutaneous nephrostomy tube for the past ten years. She consulted for a possible reconstructive procedure.
After a comprehensive preoperative evaluation, she underwent laparoscopically-assisted ureterocystoplasty. The operative time was 265 minutes with minimal blood loss. She had an unremarkable postoperative course. On follow-up, a voiding diary revealed urine volume of around 300 milliliters at 3 hour intervals, preservation of renal function, and no evidence of urinary infection.
Ureterocystoplasty was done using a combination of minimally invasive and open techniques. This procedure spared the patient a lifelong diversion with a nephrostomy tube and provided a better quality of life.

		                        			Management of nephrolithiasis in patients with urinary diversions pose a unique therapeutic challenge
for the following reasons: 1) retrograde ureteral access is difficult to perform through a bowel diversion
and 2) percutaneous renal access becomes challenging because of inability to do a retrograde pyelogram.
For this reason, image-guided access through a combined ultrasound and fluoroscopic guidance are
both necessary. This clinical problem becomes even more complicated when dealing with a solitary
functioning kidney. Treatment should be precise in order to avoid any complications that may progress
to renal failure. Presented here is a 15-year-old male adolescent who had previously undergone a radical
cystectomy with an ileal conduit for a rhabdomyosarcoma of the bladder last 2008, and complained of
flank pain, fever and foul-smelling urine. Imaging studies showed left obstructive hydronephrosis with
ureterolithiasis and nephrolithiasis, and an atrophic contralateral kidney. A preliminary nephrostomy
tube drainage was done to recover renal function, followed later by percutaneous endoscopic stone
management. Discussed here are the challenges involved in his therapy as well as the advantages of
a stepwise approach including the short-term outcomes.

		                        			The concept of functional preservation after orthotopic neobladder construction has gradually attracted attention. Reconstruction of urine storage and voiding is the basic function preservation of orthotopic neobladder. Clinical exploration mainly focuses on the optimization of neobladder reconstruction methods and procedures, and there is still a lack of summary of existing surgical characteristics and high-quality functional comparative studies. For strictly selected patients, on the basis of tumor control and standardized postoperative rehabilitation guidance, most patients with preserved nerve can retain satisfied sexual function after surgery. The protection of neurovascular bundle and ancillary structures combined with postoperative exercise is crucial to the improvement of urinary continence. According to the characteristics of patients, choosing the appropriate urinary diversion methods and function preserving can help patients establish a normal life style after surgery and improve their self-image and quality of life.

		                        			OBJECTIVE:
		                        			To compare the short-term effects and long-term outcomes of incisional procedure and dilatation procedure to manage diverticular neck in percutaneous nephrolithotomy for diverticular stones.
		                        		
		                        			METHODS:
		                        			Clinical data of 61 patients with diverticular stones who underwent percutaneous nephrolithotomy from June 2009 to January 2019 were retrospectively collected and analyzed, which was as follous: (1) basic information: age, gender, body mass index (BMI), American Society of Anesthesiology (ASA) classifications and preoperative symptoms.(2)stone characteristic and procedure-related data: location and size of stone, skinned renal access length and procedure time.(3)perioperative clinical data: hemoglobin drop, Clavien's classification and stone-free rate. Long-term follow-ups were performed for more than 5 years after the patients were discharged.
		                        		
		                        			RESULTS:
		                        			Fifty-three patients were included based on the inclusion and exclusion criteria, and were divided into the dilation group (n=37) and the incision group (n=16) by the treatment methods of diverticular neck. There were 24 male patients (45.3%) and 29 female patients (54.7%), with a mean age of 39.96±12.88 years. Stones were mainly located in the upper pole (n=32, 60.38%) and posterior area (n=41, 77.4%), with a predominance of single stone (n=36, 67.9%). There was no statistically significant difference in demographic data and stone characteristics between the two groups except for age and stone burden. Forty-five patients (84.9%) reached stone-free status after surgeries, and 44 patients (83.0%) postoperative symptoms improved. Twelve patients were lost to the follow-ups, and 41 cases were followed up for an average of 77 months. One recurrence occurred 1 year after surgery. Fifteen patients underwent operations within the past 5 years and the overall 5-year recurrence rate for the remaining 26 patients was 34.6%. There was no statistically significant difference in the incidence of perioperative complications, postoperative stone-free rate and recurrence rate between the two groups, and the recurrence rate was significantly higher 5 years postoperatively than 1 year postoperatively. The proportion of the patients who remained lithotripsy-free and residual stone status decreased significantly.
		                        		
		                        			CONCLUSION
		                        			Both incisional and dilatation procedures in percutaneous nephrolithotomy to manage diverticular neck could bring the satisfactory postoperative stone free rate. The recurrence rate was about 30% to 40% 5 years after surgery.

		                        			OBJECTIVE:
		                        			To summarize the initial clinical experience and follow-up results of the treatment for ureteroileal anastomotic stricture after radical cystectomy with Allium coated metal ureteral stent.
		                        		
		                        			METHODS:
		                        			From September 2018 to September 2019, 8 patients with ureteroileal anastomotic stricture after radical cystectomy underwent Allium ureteral stent insertion in Peking University People's Hospital and People's Hospital of Daxing District. The preoperative renal pelvis width under ultrasound was collected to evaluate the postoperative hydronephrosis, creatinine and urea nitrogen (BUN) before and after surgery, perioperative infection, and stent-related complications. The serum creatinine and BUN, renal pelvis width under ultrasound, urography and abdominal plain film (KUB) were reviewed at the end of 1, 3, and 6 months and annually postoperatively to observe the stent position and morphology. The long-term stent patency rate, complication rate, renal function and hydronephrosis were followed up and analyzed. The t-test or rank-sum test was used to compare the measurement data of the matched sample from the preoperative to the last follow-up.
		                        		
		                        			RESULTS:
		                        			In the study, 6 cases (7 sides) were ureteral ileal conduit stricture, and 2 cases (3 sides) ureteral orthotopic neobladder stricture. Before surgery, 5 patients underwent long-term indwelling of a single J ureteral stent, with an average indwelling time of (20.6±8.8) months and an average replacement frequency of (3.6±1.3) months/time. The mean width of renal pelvis was (26.5±9.1) mm on preoperative renal ultrasonography. Among them, 6 patients were successfully indwelled with Allium coated metal ureteral stent by retrograde approach, and 2 patients by combination of double-endoscopy and ante-retrograde approach. No surgery-related complications during perioperative period were observed. The mean follow-up period was 9.8 months and Allium stent and ureter remained unobstructed in all the patients at the last follow-up without replacement or removal. Compared with preoperative data, the mean width of renal pelvis and mean blood urea nitrogen (BUN) in the last follow-up period were significantly reduced [(26.5±9.1) mm vs. (13.4±2.5) mm, P=0.008; (11.6±2.3) mmol/L vs. (10.2±2.2) mmol/L, P=0.017], however, there were no significant differences in the average serum creatinine or hemoglobin (P>0.05). Ureteroileal anastomotic re-stricture and other stent-related complications were not observed in all the patients by antegrade urography.
		                        		
		                        			CONCLUSION
		                        			Allium coated metal ureteral stent could be used for the treatment for ureteroileal anastomotic stricture, which could maintain relatively long-term patency rate and protect renal function. The indwelling time was longer and it could improve quality of life of patients.

		                        			OBJECTIVE:
		                        			To evaluate the effectiveness of super-selective renal artery embolization in treatment of post-percutaneous nephrolithotomy bleeding, and to analyse the causes of failure embolization.
		                        		
		                        			METHODS:
		                        			In the study, 65 post-percutaneous nephrolithotomy patients with severe renal bleeding and hemodynamic instability were treated by super-selective renal artery embolization. First of all, we performed selective renal arteriography. After clarifying the location of the bleeding, superselective intubation of the injured vessel with a microcatheter was carried out. Then the injured vessel was embolized with Tornado micro-coil. When complete embolization was not achieved with micro-coil, a small amount of gelatin sponge particles were added. If there was no positive finding of the beginning selective renal arteriography, the following measures could be taken to prevent missing lesions: (1) Abdominal aorta angiography was performed to determine whether there were anatomical variations, such as accessory renal arteries or multiple renal arteries; (2) Ultra-selective intubation angiography next to the nephrostomy tube path was performed; (3) Renal arteriography was repeated; (4) Renal arteriography after removing the nephrostomy tube while retaining the puncture channel. We evaluated the different angiographic findings and analysed the causes of embolization failure.
		                        		
		                        			RESULTS:
		                        			Bleeding was successfully controled in 60 patients (62 kidneys) whose renal arteriography was postive. Positive findings included: pseudoaneurysm formation, patchy contrast extravasation, pseudoaneurysm combined with arteriovenous fistula, contrast agent entering the collection system, extravascular perinephric leakage of contrast. After first embolization, bleeding was controled in 53 patients (55 kidneys). The success rate after the first and second embolization was 88.7% and 96.7% respectively. The second session was required because of failure to demonstrate bleeding arteries during the first session (4 patients, 57.1%) and recurrent hemorrhage of the embolized injured arteries (2 patients, 28.6%). In 5 patients with no positive findings, after conservative treatment, hematuria disappeared. All the patients were followed up for 3, 6, and 12 months after embolization, and no hematuria occurred again, and no sustained and serious renal insufficiency.
		                        		
		                        			CONCLUSION
		                        			Super-selective renal artery embolization is an effective treatment for post percutaneous nephrolithotomy bleeding. The main cause of failure is omitting of injured arteries during renal arteriography. Renal artery branch injury has various manifestations. Attention should paid to the anatomical variation of the renal artery, and patient and meticulous superselective intubation angiography is the key to avoiding missing the lesion and improving the success rate of embolization.

		                        			OBJECTIVE:
		                        			To discuss the efficacy and safety of simultaneous bilateral endoscopic surgery (SBES) for bilateral upper urinary tract calculi, and to summarize the initial experience.
		                        		
		                        			METHODS:
		                        			Patients diagnosed with bilateral upper urinary tract calculi who underwent SBES in the Department of Urology, Beijing Chao-Yang Hospital from January 2019 to January 2020 were enrolled retrospectively. The demographic and clinical data of the patients were recorded, and the operation status, stone free rate (SFR) and peri-operative complications were analyzed. The primary end point was SFR, and second end point was peri-operative complications.
		                        		
		                        			RESULTS:
		                        			A total of 23 patients underwent SBES, of which SBES was completed in 19 patients (12 males, and 7 females). The mean age was (41.3±12.0) years. Fourteen patients underwent modified supine position surgery and 4 patients in prone split-leg position. There was no statistical difference in the demographic and baseline clinical data of the patients in different positions. One patient underwent right percutaneous nephrolithotomy (PCNL) and left endoscopic combined intra-renal surgery (ECIRS) in the prone split-leg position, while 18 patients received simul-taneous surgery with PCNL and contralateral retrograde intra-renal surgery (RIRS). The mean anesthesia and operation time was (128.7±26.5) min and (70.7±20.3) min, respectively, which was significantly longer in the patients with prone split-leg position than in the patients with modified supine position, anesthesia time in the patients with prone split-leg position and modified supine position: (148.4±20.4) min vs. (121.6±25.3) min, respectively, t=-2.121, P=0.049, while the operation time in the patients with prone split-leg position and modified supine position: (86.4±21.1) min vs. (65.1±17.4) min, respectively, t=-2.222, P=0.040. There was no significant difference between the two groups in indwelling of nephrostomy [prone split-leg position and modified supine position: (2.6±0.9) d vs. (2.1±1.0) d, respectively; t=-0.880, P=0.391] and the length of hospital stay [prone split-leg position and modified supine position: (6.0±2.7) d vs. (5.2±1.8) d, respectively; t=-0.731, P=0.475]. One month after the operation, the SFR was 78.9%, and 3 patients had minor peri-operative complications (Clavien-Dindo grades Ⅰ/Ⅱ) without any serious complications (Clavien-Dindo grades Ⅲ/Ⅳ/Ⅴ).
		                        		
		                        			CONCLUSION
		                        			The simultaneous bilateral endoscopic surgery would decrease the operation time and anesthesia exposure under the premise of ensuring the SFR, which is helpful to reduce the risk of peri-operative complications, especially to the patients who can not tolerate the second-stage or long-time operation.

		                        			OBJECTIVE:
		                        			To compare the outcomes of endoscopic combined ultrasound-guided access (EUGA) with the conventional ultrasound-guided access (UGA) to achieve percutaneous renal access in endoscopic combined intrarenal surgery (ECIRS).
		                        		
		                        			METHODS:
		                        			A retrospective review of 53 patients undergoing ECIRS to treat upper urinary tract calculi between January 2017 and October 2019 was con-ducted. All of the cases were of complex upper urinary tract stones larger than 2 cm in diameter. The com-plex stone situations, such as multiple renal calyces calculi or staghorn calculi necessitated ECIRS. Under general anesthesia, the patients were placed in the galdakao-modified supine valdivia (GMSV) position, thus allowing both antegrade and retrograde accesss. The patients were divided to UGA and EUGA groups according to the protocol of achieving percutaneous renal access. In 28 cases, endoscopic combined ultrasound-guided accesss were obtained. Puncture and dilation were performed under direct flexible ureteroscopic visualization, while percutaneous renal access of 25 cases were performed with the conventional technique employing ultrasound guidance. Demographic and perioperative information, such as stone burden, presence of hydronephrosis and number of calyces involved was compared. Primary outcomes included total operative time, renal access time, repeat puncture, hemoglobin level, perioperative complications, and stone-free rate.
		                        		
		                        			RESULTS:
		                        			No major intra-operative complication was recorded in all the 53 ECRIS. No significant difference was observed between the groups in age and gender. There was no significant difference in body mass index[BMI (29.21±3.14) kg/m2 vs.(28.53±2.56) kg/m2], stone burden (37.68±6.89) mm vs. (35.53±6.52) mm, number of calyces involved 2.72±0.68 vs. 2.86±0.71, presence of hydronephrosis (56.0% vs. 46.4%), total operative time (93.0±12.2) min vs. (96.8±14.2) min, hemoglobin level reduction (6.56±2.16) g/L vs. 97.54±2.64) g/L, stone-free rate (92.0% vs. 92.8%), hospital stay (5.52±0.59) d vs. (5.64±0.62) d, perioperative complication rate (8.0% vs. 7.2%). Two patients in EUGA group experienced perioperative complications (one urinary tract infection and one hematuria) while two patients in UGA group experienced perioperative urinary tract infection. None in both groups received blood transfusion. The patients undergoing EUGA had shorter renal access time [(4.0±0.7) min vs. (6.8±2.6) min, P < 0.01] and less repeat puncture (0 vs. 4 cases, P < 0.05).
		                        		
		                        			CONCLUSION
		                        			EUGA is an optimal technique to establish percutaneous renal access in ECIRS, which minimizes access time and repeated procedures.

10.Study and Analysis on the Test of Representative Products for Percutaneous Renal Puncture Device.
Chinese Journal of Medical Instrumentation 2019;43(3):214-216
		                        		
		                        			
		                        			Percutaneous renal puncture device has very important clinical value. Qualified percutaneous renal puncture device is one of the important ways to evaluate its safety and efficacy, and it is also an important prerequisite for the device to be marketed in China. When manufactuers test the product, the selection of representative products is suggested from the aspects of performance parameter, structure, material and production process.
