The surgical management of kidney-stone disease has undergone dramatic changes over the past 20 years. The introduction and development of percutaneous renal surgery, extracorporeal shock-wave lithotripsy, ureteroscopy, and technical advances in the available modalities for intracorporeal lithotripsy have led to a revolution in the surgicalmanagement of kidney-stone disease. The indications for open kidney-stone surgery have been narrowed significantly, and for the most part open surgery has become a second or third line treatment option. In this article, the authors attempt to better define acceptable indications for open kidney-stone surgery, to review commonly accepted advantages of open stone procedures and to establish expected results and outcomes following open surgery for kidney-stone disease

33 cases of renal calculus received opene surgery for pyelonephrolithotomy (the operative procedres described by L.Q. Cat and N.B. Trieu - 1971, Resnick. M.I.1981) in Urology Department of hospital Viet Duc and hospital No 103. Renal function was determined with serum, blood ure nitrogen (BUN), creatinine and creatinine clearance. Creatinine clearance was calculated up on equations of Cockroft and Gault (1976). Author compared renal function preoperatively and postoperatively (5 -7 days). There was no significant difference in serum ure nitrogen (BUN), creatinin (n= 33) between preoperative and post operative (p>0.05). There was significant in creatinine clearance postoperation (p < 0.05).

OBJECTIVETo evaluate the feasibility of retroperitoneal laparoscopic surgery combined with ureteroscopic lithotomy through the pelvis for treatment of renal and ureteral calculi.

METHODSIn February 2010, 2 patients with renal and ureteral calculi underwent retroperitoneal laparoscopic surgery combined with ureteroscopic lithotomy through the pelvis.

RESULTSThe operation time in these two cases was 70 and 80 min, and the volume of intraoperative blood loss was about 20 ml. The exposure was excellent, and the patient recovered rapidly without complications or residual calculi.

CONCLUSIONRetroperitoneal laparoscopic surgery combined with ureteroscopic lithotomy through the pelvis is feasible for treatment of renal and ureteral calculi.

OBJECTIVE: To explore the feasibility of rapid and accurate three-dimensional (3D) image reconstruction using Uromedix-3D software for urological surgery. METHODS: The original renal thin-slice enhancement CT data were obtained from patients with kidney lesions treated in our hospital between December, 2015 and October, 2018. The self-developed Uromedix- 3D system was used to reconstruct the normal kidney structures, blood vessels, collecting systems and the lesions. The spatial anatomic relationships of the structures were measured and digitized for surgical planning. RESULTS: 3D reconstruction of the kidneys was performed in a total of 173 cases, and the mean time for reconstruction was 31.24±2.012 min. Of these cases, 147 (84.9%) had renal tumors, and 2 had renal tumors with tumor thrombus. In addition to renal tumors, the Uromedix-3D system was also used for reconstructing other lesions including UPJO, kidney stones and retroperitoneal masses. Renal artery reconstruction was performed in 170 cases, which allowed observation of the precise terminal branches (up to 7th grade arterial branch) of the artery; 109 (64%) cases showed the 5th grade arterial branch or above. Renal artery variations were detected in 37 cases, including accessory renal artery (24 cases) and multiple renal arteries (13 cases). The renal veins were reconstructed in 164 cases, and second grade or above (up to the 4th grade) vein branches were observed in 138 (84%) cases. CONCLUSIONS Uromedix-3D system can accurately and efficiently reconstruct the 3D structure of human kidneys and the renal lesions based on enhanced CT data. The reconstructed 3D model allows objective assessment of the spatial anatomical relationship of the lesions to provide assistance in surgical planning.

OBJECTIVE: To evaluate the long-term efficacy and safety of ultrasound-guided percutaneous nephrolithotomy (PCNL) in the treatment of patients with solitary kidney stones. METHODS: The clinical data of 22 patients with solitary kidney stones treated with PCNL in Peking University People's Hospital from September 2008 to June 2014, with the follow-up data of more than 5 years were analyzed retrospectively. Perioperative indicators, postoperative stone free rate (SFR) and incidence of complications were recorded. Ultrasonography was used to evaluate the long-term stones recurrence rate. Serum creatinine and estimated glomerular filtration rate (eGFR) were used to assess the long-term renal function. RESULTS: In this group of 22 patients, the average age was (50.3±11.8) years, with 10 cases of anatomic solitary kidneys, 12 functional solitary kidneys, and the median stone diameter was 1.65 (1.1-3.9) cm. All the patients had multiple stones, including 7 cases of staghorn stones. The median pre-operative serum creatinine was 104.5 (60.0-460.0) μmol/L, and the mean eGFR was (60.3±29.4) mL/min, showing no statistically significant difference compared with that before surgery. The mean operative time was (88.2±42.0) min, and there were 11 cases of single-channel and double-channel PCNL. The median serum creatinine on the first day after surgery was 102.0 (63.0-364.0) μmol/L, and the mean eGFR was (58.0±25.1) mL/min. The mean postoperative hospital stay was (8.7±5.2) days. In this group, 5 patients (22.7%) presented short-term complications, among which 4 patients presented postoperative infection and massive hemorrhage at the same time, which improved after conservative treatment, and 1 patient presented pleural injury and improved after closed thoracic drainage. Two patients (9.1%) developed long-term complications, and ureteral stricture occurred 3 months after operation, which improved after balloon dilatation. The median follow-up time was 6.2 (4.7-11.1) years. The median serum creatinine at the last follow-up was 104.0 (72.4-377.0) μmol/L, and the mean eGFR was (60.1±23.7) mL/min, showing no statistically significant difference compared with that before surgery. Renal function decreased in 6 patients (27.3%). Initial and final SFR were 72.7% and 100%, respectively. During the 6.2-year follow-up, 9 patients (40.9%) experienced recurrence of kidney stone. After stone recurrence, 13 lithotomy surgeries were performed, and the SFR by the latest follow-up was 63.6%. CONCLUSION This study had the longest follow-up time for patients with solitary kidney stones after PCNL reported at home and abroad. Ultrasound-guided standard PCNL was safe and effective in the treatment of solitary kidney stones. Long-term follow-up results showed that the recurrence rate of kidney stones was still high, but the long-term renal function was stable after operation, and some patients showed mild renal function decline.
