ObjectiveTo evaluate the safety and efficacy of flexible ureteroscopic lithotripsy for renal stones of longer than 2 cm in diameter. MethodsFrom August 2012 to July 2014, 15 selected patients with renal calculi of longer than 2 cm in diameter underwent flexible ureteroscopic lithotripsy with holmium laser by the same surgeon. Preoperative indwelling ureteral stent was performed for 1-2 weeks, and super smooth guidewire was inserted after checking and dilation of the ureter was performed with F8.0/9.8 rigid ureterosope. Flexible ureteroscope sheath was inserted through guidewire. Ureterosope was followed by flexible ureteroscope sheath. Larger stone fragments were removed by basket. ResultsThe success rate of ureteroscopic insertion was 100% and no severe intraoperative complications occurred. The operation time ranged from 50 to 125 minutes averaging 75. No ureteral perforations or pyonephrosis or acute renal insufficiency occurred. Four patients had high fever after operation and improved after positive anti-infection treatment. After 2 days, the stone-free rate was 73.3% (11/15) by reviewing KUB. The follow-up of 4 weeks showed the stone-free rate was 86.7% (13/15). One case of stone fragments retained in the middle and lower ureter and the fragments were taken out by ureteroscopic lithotripsy. The other case of renal residual calculi was operated by flexible ureteroscope holmium laser lithotripsy in two stage. ConclusionFlexible ureteroscopic lithotripsy is a favorable option for patients with renal stones of longer than 2 cm in diameter, especially for recurrent renal calculi.
ObjectiveTo systematically review the efficacy and safety of laparoscopic pyeloplasty (LP) versus open pyeloplasty (OP) for patients with ureterpelvic junction obstruction (UPJO). MethodsWe electronically searched databases including PubMed, The Cochrane Library (Issue 11, 2015), Sciverse, VIP, WanFang Data and CNKI from inception to Dec., 2015, to collect randomized controlled trials (RCTs) and non-randomized clinical controlled trials (CCTs) about LP versus OP for UPJO patients. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 38 studies including 8 RCTs and 30 CCTs were included. The results of meta-analysis based on RCTs showed that, there were no significant differences in successful operation rate (OR=0.50, 95%CI 0.20 to 1.24, P=0.13) and the incidence of postoperative complications (OR=1.19, 95%CI 0.61 to 2.31, P=0.62) between the OP group and the LP group; The operation time of the OP group was shorter than that of the LP group (MD=62.07, 95%CI 3.94 to 120.19, P=0.04), but this difference was not found in subgroup analysis of retroperitoneal approach (MD=49.99, 95%CI -23.69 to 123.67, P=0.18); The hospital stay of the LP group was shorter than that of the OP group (MD=-3.96, 95%CI -4.92 to -2.99, P<0.0001). The results of meta-analysis based on CCTs showed that, there was no significant difference in successful operation rate between two groups (OR=1.34, 95%CI 0.84 to 2.16, P=0.22), and similar results were found in subgroup analysis of transperitoneal or retroperitoneal approaches; The incidence of postoperative complications of the LP group was shorter than that of the OP group (OR=0.51, 95%CI 0.37 to 0.69, P<0.0001); The hospital stay of the LP group was shorter than that of the OP group (MD=-3.87, 95%CI -4.90 to -2.83, P<0.00001) and similar result was found in subgroup analysis of transperitoneal approach (MD=-4.08, 95%CI -5.21 to -2.95, P<0.0001); There was no significant difference between two groups in operation time (MD=24.15, 95%CI -7.56 to 55.87, P=0.14). ConclusionCurrent evidence shows that, the successful operation rate between LP and OP operations is similar, but the LP operation has less incidence of postoperative complication and shorter hospital stay. Due to limited quality of the included studies, the above conclusion needs more high quality studies to verify.
Objective To evaluate the clinical value of ureteroscope in cholelithiasis treated by laparoscopic surgery. Methods The clinical data of 36 patients admitted because of hepatolithus with ureteroscope combination in laparoscopic surgery from February 2007 to September 2009 in Guidong People’s Hospital of Guangxi were analyzed retrospectively. Results In 33 cases, stones were removed once by ureteroscope in laparoscopic surgery with residual stones (in 3 cases residual stone were removed secondarily through T tube) and the other 3 cases were transferred to laparotomy forcedly due to bleeding of biliary duct and vessels of porta hepatis and tearing of bile duct. During operation, blood loss was 30-280 (94.51±54.70) ml; operation time was 110-260 (147.22±48.45) min; recovery time of bowel movement was 1-3 (2.03±0.76) d; postoperative hospitalization time was 6-13 (7.12±1.65) d (some discharged with T tube); the time of patients of T tubes pulled out was 28-45 (38.92±6.52) d. Bile leakage happened in 1 case and infection of biliary tract in 1 case, no complications such as biliary stricture or bile duct bleeding were found after operation. Conclusions Treatment of intrahepatic bile duct or a single extra-hepatic sand-like stones with ureteroscopy usage in laparoscopic surgery is feasible and less invasive. It is a minimally invasive treatment for intra- or extra-hepatic stones due to rapidly postoperative rehabilitation.

Tissue engineering technology and stem cell research based on tissue engineering have made great progresses in overcoming the problems of tissue and organ damage, functional loss and surgical complications. Traditional method is to use biological substitute materials to repair tissues, while tissue engineering technology focuses on combining seed cells with biological materials to form biological tissues with the same structure and function as its own to repair tissue defects. The advantage is that such tissue engineering organs and tissues can solve the problem that the donor material is limited, and effectively reduce complications. The purpose of tissue engineering is to find suitable seed cells and biomaterials which can replace the biological function of original tissue and build suitable microenvironment in vivo. This paper mainly describes current technologies of tissue engineering in various fields of urology, and discusses the future trend of tissue engineering technology in the treatment of complex urinary diseases. The results of this study show that although there are relatively few clinical trials, the good results of the existing studies on animal models reveal a bright future of tissue engineering technology for the treatment of various urinary diseases.
Objective To explore the advantages of postoperative chest drainage with 16F urinary catheter for video- assisted thoracoscopic surgery (VATS) lobectomy. Methods Data of 102 patients (October to December 2015) who under- went VATS lobectomy of lung disease with insertion of catheter (16 F urinary catheter or 28 F chest tube) were analyzed. The patients were divided into two groups including a 16F group (49 patients, with 16 F urinary catheter) and a 18F group (53 patients, with 18F chest drainage tube).The following post-operative data were evaluated: primary healing of tube inci- sion, chest X ray abnormalities (pneumothorax, pleural effusion, subcutaneous emphysema, and hematoma), drainage time, re-insert the drainage tube, and wound healing at the site of insertion. Results Both groups were similar in age, gender, co-morbidity and pathological evaluation of resected specimens. After adjustment, no statistically significant difference was found between the two groups in pulmonary complications (30.6% vs. 28.3%, P=0.102), subcutaneous emphysema (60.0% vs. 6.7%, P=0.011), required intervention (2.0% vs. 5.7%, P=0.048). The average total drainage volume in the 16F group (587.3±323.7 ml) was less than that of the 28 F group (824.1±444.3 ml, P=0.000). The rate of primary healing at the site of insertion in the 16 F group (100.0%) was higher than that in the 28F group (58.5%, P=0.014). A significant difference was found in the drainage time and post-operative length of stay between the two groups (54.2±28.6 h vs. 95.6±65.5 h，4.2±1.4 d vs. 6.5±3.0 d). Conclusion Since 16F urinary catheter has advantage in fast track rehabilitation and low risk of pulmonary complications, the use of 16F urinary catheter is appropriate after VATS pulmonary lobectomy.
