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.

OBJECTIVETo present the technique and experience of robotic-assisted laparoscopic radical cystectomy (RARC) by da Vinci surgical system.

METHODSFrom December 2007 to September 2008, 4 patients underwent RARC and urinary diversion. The age of patients was 44 to 63 years old. The body mass index was 22.8 to 27.7. All their clinical stages were lower than T2N0M0. The technique for RARC involving ureters dissection, posterior dissection, lateral pedicle control, anterior dissection, dorsal vein complex control, neurovascular bundles sparing, lymphadenectomy, ureter-ileal anastomosis, urethra-neobladder anastomosis to either ileal conduit urinary diversion or neobladder reconstruction performed extracorporeally.

RESULTSAll the operations were accomplished successfully. The urinary diversion of 2 case was ileal conduit and others was ileal orthophoria neobladder. The operation time was 300 to 450 min. The time of radical cystectomy was 150 to 180 min. The estimated blood loss was 100 to 500 ml. The postoperative hospital stay was 9 to 35 d. The bed rest time was 4 to 9 d. There was 1 patients who had incomplete intestinal obstruction at 8th postoperative day cured by conservative therapy. The patients were followed up for 3 to 12 months, all patients survived without tumor recurrence. The patients have satisfied urinary continence and normal renal functions without hydronephrosis after the operation.

CONCLUSIONSRARC is small incision and safe, the results are definite. It is one of the direction of minimally invasive urologic surgery.

OBJECTIVETo report the surgical techniques and results of an 8-year follow-up study of 42 patients with a modified orthotopic ileal neobladder restoring normal anatomical relationship.

METHODSTotal cystoprostatectomy was performed extraperitoneally. A 45 - 50 cm segment of the ileal loop was isolated, detubularized, and reconfigured into an "M"-shape to form a pouch. Bilateral ureters were implanted by inserting 1 cm distal segment into the pouch. The bottom of pouch was opened and anastomosed with the urethra.

RESULTSForty-two patients were followed up for 6 to 96 months,90.5% of whom were continent in the daytime, and 85.7% at night. Two patients had a difficulty in urination. The average volume of the pouch was (361 +/- 48) ml at 12 months postoperation. Urodynamic examination showed the average peak voiding pressure was (86.8 +/- 21.4) cm H(2)O. The average maximum flow rate (Qmax) was (18.4 +/- 6.1) ml/s. No remarkable ureter reflux and obstruction were found. No patient was detected to have urethral carcinoma.

CONCLUSIONSExtraperitoneal cystectomy can avoid the tumor contamination of the abdomen and intestinal interference of the operative field. The ureter-inserting implantation technique is a simple anti-reflux anastomosis method with less ureter stenosis rate. Isolating the neobladder and ureters from the peritoneal cavity can reduce the postoperative complications, such as adhesive ileus, internal hernia, and urine leakage into the peritoneal cavity. The neobladder is similar to the original bladder in position, volume, shape and anti-reflux ureter connection.

OBJECTIVESTo evaluate modified cystectomy with preservation of erectile and ejaculatory functions in men with nonmalignant bladder disease.

METHODSSeven cases with average age of 27 years presented with bladder disease necessitating cystectomy, including 2 cases of tuberculous contractile bladder, 1 case of extensive polypoid cystitis glandularis, 4 cases of late stage of neurogenic bladder. All patients wished to maintain erectile and ejaculatory functions after the operation. We performed a modified simple cystectomy with preservation of the vasa deferens, seminal vesicles, prostate and neurovascular bundles, as well as construction of an Indiana pouch or ileal neobladder.

RESULTSAverage operative time was 5 h 45 min without perioperative complications in this group. Follow-up ranged from 9 to 60 months. Erectile and ejaculatory functions were normal in all cases. All patients remained completely continent and no dysuria in neobladder, and there was no difficulty in inserting catheter to empty pouch. Upper urinary tract was in good condition 3 and 24 months after operation.

CONCLUSIONSModified cystectomy with preservation of the vasa deferens, seminal vesicles, prostate and neurovascular bundles is an effective and reliable option for the patients who wish to maintain their fertility and erectile function after surgery.

OBJECTIVETo evaluate the effect of sexual-nerve-sparing radical cystectomy.

METHODSThirty-two male patients were treated with sexual-nerve-sparing radical cystectomy in our hospital in the past 5 years. The age of the patients ranged from 38 to 72 years, with the course of the disease ranging from 2 days to 20 years. All of them were potent preoperatively. Radical cystectomy was performed antegradely and retrogradely with the neurovascular bundle spared.

RESULTSThe patients were followed up for 6 to 54 months, 3 achieved sexual activity of Grade I, 6 Grade II and 23 Grade III after the operation. The recovery time of erectile function ranged from 2 to 14 months, averaging at 4. 5 months.

CONCLUSIONWhenever condition suits, sexual-nerve-sparing radical cystectomy is to be strongly recommended.

PURPOSE: We performed nerve-sparing robot-assisted radical cystectomy (nsRARC) and compared the operative outcomes of nsRARC and open radical cystectomy (ORC). MATERIALS AND METHODS: The data of 38 patients that underwent ORC or nsRARC for bladder cancer between July 2009 and April 2014 (23 ORC and 15 RARC) were retrospectively analyzed. Data were collected on patient demographics, pathologic stages, perioperative outcomes, and oncologic outcomes as well as on erectile function. Five-year overall survival and cancer-specific survival were analyzed using the Kaplan-Meier method. Erection function recovery was defined as the ability to achieve penetration ≥50% of the time and to maintain an erection sufficient enough for penetration ≥50% of the time at 12 months after surgery. RESULTS: No significant differences were found between the nsRARC and ORC groups in terms of age, sex, body mass index, American Society of Anesthesiologists physical status, or clinical stage. Mean estimated blood loss was significantly less in the nsRARC group (205.3 mL vs. 394 mL, p=0.011), but mean operative time was significantly greater (520.3 minutes vs. 415.0 minutes, p=0.004). Five-year overall survival and cancer-specific survival were 86.7% and 86.7%, respectively, for nsRARC, and 77.7% and 86.7% for ORC. With respect to erectile function, the overall postoperative potency rate at 12 months was 40.0% in the RARC group and 9.5% in the ORC group, and this difference was significant (p=0.021). CONCLUSIONS: Our clinical experiences indicate nsRARC in selected patients is a feasible procedure in terms of oncologic outcome and that it preserves erectile function relatively effectively.

PURPOSE: To compare the clinical outcomes of the arthroscopic treatments for popliteal cysts with and without cystectomy. METHODS: PubMed/MEDLINE, EMBASE, KoreaMed, and Cochrane Library were searched from the earliest available date of indexing through August 2016. The methodological quality of all articles was assessed according to the Coleman methodology score (CMS). Studies were grouped according to the surgical method, and a meta-analysis was conducted to identify the unsuccessful clinical outcome and complication rates. RESULTS: Nine studies were included; the mean CMS was 67.33 (standard deviation, 8.75 points). Cystectomy was reported in five studies; cystectomy was not performed in four studies. The odds ratio of unsuccessful clinical outcomes evaluated by Rauschning and Lindgren score was 122.05 (p<0.001) with cystectomy and 58.12 (p<0.001) without cystectomy. The effect size of complications was 0.16 (p<0.001) with cystectomy and 0.03 (p<0.001) without cystectomy. The recurrence rate was 0% with cystectomy and 6.4% without cystectomy. CONCLUSIONS: All the currently available studies showed satisfactory outcomes in both with and without cystectomy groups. However, arthroscopic cystectomy concurrently performed with management of intra-articular lesions was associated with a relatively low recurrence rate and a relatively high incidence of complications.

BACKGROUNDBladder carcinoma is the most common malignant urological tumor in China. We present our preliminary experience and results of laparoscopic radical cystectomy (LRC) with orthotopic ileal neobladder in female patients with bladder carcinoma.

METHODSFrom February 2003 to February 2008, 14 female patients with bladder carcinoma underwent LRC with orthotopic ileal neobladder. Nine of these patients underwent hysterectomy and ovariectomy, and the other 5 had preservation of the uterus and ovarian appendage. Standard bilateral pelvic lymphadenectomy was followed by radical cystectomy that was completed laparoscopically with hysterectomy and ovariectomy when needed. The tumor was removed by a 4 - 5 cm lower midline abdominal incision, followed by the construction of ileal neobladder and the extracorporeal anastomosis of ureter-neobladder. The neobladder was anastomosed to the urethral stump under a laparoscope.

RESULTSThe mean operative time and blood loss in the 14 patients were 350.2 minutes and 349.8 ml, respectively. Postoperative complications included uretero-pouch anastomotic stricture in 1 patient and pouch-vaginal fistula in 1 patient. Follow-up time of all patients ranged from 3 to 60 months, and 12 patients were followed up for more than 6 months and achieved micturition in half a year. One patient had occasional day-time urinary incontinence and 2 had night-time incontinence. Two patients who had undergone hysterectomy and ovariectomy had voiding difficulties after one year, which was treated by intermittent self-catheterization. The mean volume of the neobladder and the residual urine were 333.6 ml and 31.2 ml, respectively. Surgical margins were tumor free for all patients. One patient had bone metastasis and died 11 months after the operation.

CONCLUSIONSLRC with orthotopic ileal neobladder in female patients is a technically feasible, safe and mini-invasive procedure with a low morbidity and acceptable neobladder function. Long-term follow-up is required to confirm the neobladder function and oncological outcomes.

BACKGROUNDAn important milestone in the area of urinary diversion was the advent of a series of orthotopic bladder substitution (OBS). However, reconstruction of OBS by the traditional hand suture method (THSM) is a time-consuming process. Stapling techniques are considered to be inferior to hand-sewn methods. We report our experience and functional results in patients with W-ileal neobladder by a hand-assisted-drawing-needle running suture (HADNRS).

METHODSBetween April 1993 and December 2011, 347 patients (338 men and 9 women) aged 28 - 77 years (median age: 59 years) underwent radical cystectomy, followed by the creation of a modified W-ileal neobladder by HADNRS with a curved needle. A total of 347 (20 patients in 2003) were evaluated by urodynamic tests.

RESULTSThe operative time ranged from 110 to 310 minutes (mean 148 minutes), and the mean time of reconstruction by HADNRS, excluding ureterointestinal and ileouretral anastomosis, was (20.2 ± 4.3) minutes. Histopathological analysis of removed specimens showed that 317 patients had transitional cell bladder carcinoma. Of these 317 patients, 19 also had squamous carcinoma and 13 had adenocarcinoma. Glandularis and prostate cancer occurred in 16 and 14 patients, respectively. Three patients (0.8%) had neobladder abdominal fistula. No other early complications or injury to the surgeon's hands occurred due to HADNRS. Of the 20 cases with urodynamic examinations in 2003, two suffered from daytime incontinence and six had nocturnal incontinence. The maximum capacity of the neobladder was (492.9 ± 177.8) ml, and the maximum pressure within the reservoir at the end of filling was (32.1 ± 8.6) cmH2O.

CONCLUSIONReconstruction of W-ileal neobladder by HADNRS is effective and economical.
