Objective To explore the application of laparoscopic pneumovesical enucleation of the prostate by using this procedure on dogs.Methods Pneumovesicum was established in 8 male dogs ages 4 to 6 under anesthesia.Three trocas 5mm in diameter were put into the bladders; the prostates were dissected and enucleated laparoscopically.The incision sites were enlarged and the prostates were removed; and a bladder fistula tube and a catheter were placed.Results The procedure was successfully performed on 7 of 8 dogs but failed in one dog due to excessive bleeding.The surgical duration was 85 to 190 min [(125± 42.3)min in average],intraoperative blood loss was 20 to 180 ml [(45 ± 30.8)ml in averagel,and the removed tissue was 12 to 36ml [(18.8 ± 7.2)ml in average].All 7 dogs urinated smoothly after surgery and no incontinence occurred.Conclusions Our study shows laparoscopic enucleation of the prostate under pneumovesicum is reasonable,feasible,efficacious,and less invasive,and causes less bleeding.This successful experiment can be applicable to our clinical needs.

目的探讨多针道单通道经皮肾镜治疗多发性肾盏结石的临床疗效。方法分析多针道单通道经皮肾镜治疗多发性肾盏结石患者42例临床资料。结果本组42例中,Ⅰ期取石33例,Ⅱ期取石9例;结石残留3例。术中及术后未发现大量出血和其他严重并发症。结论采用多针道单通道经皮肾镜取石较多通道取石创伤更小,取石成功率高。

ObjectiveTo describe the technique of a minimally invasive percutaneous nephrolithotomy for lower calyceal calculi with failed extracorporeal shock wave lithotripsy (ESWL). MethodsA total of 48 patients underwent minimally invasive percutaneous nephrolithotomy for lower calyceal calculi from April 1999 to August 2007 after failed treatment with ESWL under the guide of ultrasound. There were 41 male and 7 female patients having 35 positive calculi and 13 negative calculi constituting a mean stone burden of 0.8 cm (range 0.5-1.0 cm). ResultsIt was successful in 45 cases and failed in 3 case. The total stone clearance rate was 93.8%. The average operating time was 61 minutes. No major complications and serious blood loss were observed in these patients. Conclusions Minimally invasive percutaneous nephrolithotomy is safe and effective for the treatment of lower calyceal calculi with failed ESWL with the advantages of little injury and quick recovery.

目的探讨女性尿道憩室的诊治措施。方法分析6例女性尿道憩室患者临床资料,全部患者采用经阴道前壁径路切除憩室。结果手术均顺利完成,出院后随访,无尿瘘、尿道狭窄及尿道憩室复发。结论女性尿道憩室一经确诊,应尽早手术切除,效果良好。

Objective To discuss the complications of double J tube inside drainage and their prevention and treatment. Methods Review and analysis the clinical data Of 207 patients received transureteral cavity lithotrity and double J tube inside drainage. Results The effect of inside drainage and crutch of double J tube was well, when administered transureteral cavity lithotrity. After placed the tube, the main complications were hematuria, urinary infection, double J tube shifting, lithogenesis inside or around the tube, double J tube block and the ureter narrow after pull the tube. Conclusions Double J tube has dual effects of inside crutch and inside drainage. It has the following advantages: operation easy, usage safe and dependable, shortening the hospitalization time. After place the tube, the complications appear less than ever. They can reduce the complications occurrence when placing the tube right, pulling out the tube in the right time, and dealing in time.

Objective To evaluate the technique of Gasless Laparoscopic Retroperitoneal Ureteroli- thotomy by Single Pore. Methods 25 cases with ureterolithy underwent Gasless laparscopic ureteroli- thotomy via post-abdominal cavity approach by Single Pore. Results 23 of the 25 cases have been successful, the operation time bing 50min-160min(average 90min) and the blood loss 5 to 20ml. Ultrasound B investigation 4 to 6 weeks after the procedure showed no costracture in ureter of all cases. Conclusions Gasless laparoscopic Retroperitoneal ureterolithotomy by single pire is an eflective way to trat ureterolith with minimal trauma and safe to the patient.

目的探讨侧卧住是否可以行经尿道输尿管镜术,包括输尿管镜的检查和治疗.方法女性病人取侧卧位时曲髋80°以下,屈膝90°以下.男性病人卧侧曲髋,对侧下肢伸直用以腿架托起,其他手术方法与截石住相同.结果18例除1例输尿管口狭窄输尿管镜无法插入外,其余17例均成功完成手术.结论膀胱截石位并不是榆尿管镜术的唯一体位,必要时可以采用侧卧位行输尿管镜检查和治疗.

Purpose:Removal of ureteral calculi through nephrocutaneous tract can prevent stones from moving up to the kidney.Methods:With the patient in the lateral recumbent position, percutaneous nephrostomy under ultrasonography was performed. The tract was dilated to 16 or 18F, through which stones were first broken into small pieces and then removed from ureter by ureteroscope. Results:In 19 of the 20 cases, stones were successfully removed by one stage PUL (Percutaneous Ureterolithotomy), only one case was done by two stages because of bleeding.Conclusions:Percutaneous Ureterolithotomy under Ultrasonography results in less tissue injury and quicker recovery, and is especially suitable for those patients with upper ureteral calculi accompanied by hydronephrosis.

腹腔镜输尿管切开取石术中输尿管切口缝合以及输尿管内支架的放置比较困难.手术前后通过膀胱镜逆行插管,不仅操作繁琐,而且增加病人的痛苦.我们于1997年3月至1999年11月采用一种简易的方法行腹腔镜输尿管切开取石术10例,效果满意,报告如下.
