Complications of ureteroneocystostomy are relatively rare. Nevertheless, it would be desirable to use and operative approach that would prevent all complications. Based on our experiences with ureteroneocystostomy during the last 5.6 years, the causes, the operative methods and results were discussed. The results were as follows 1. Ureteroneocystostomy was performed in cases of primary reflux( 7 ureters), megaureter (6), ectopic ureter(5), posterior urethral valve(4) and ureterocele(3) as congenital causes. Acquired causes were iatrogenic ( 7 ureters) , tuberculosis(6), bladder ca(3) and traumatic ureteral injury(2) And causes of remained three ureters couldn`t be seeked. 2. Thirty nine of forty six ureters was performed with the method of submucosal tunnel and 7 with end to side. Among them 11 ureters with diffuse ureteral stricture were combined with the method of Vesico-psoas hitch. 3. Thirty five of thirty eight ureters was successfully corrected. Postoperative complications were contracted VUR in 2 cases, ipsilateral VUR, obstruction and unimproved renal function in each one case.

Postoperative biliary stricture is a relatively rare but serious complication of biliary surgery. Although Rouxen-Y hepaticojejunostomy or choledochojejunostomy are well-established and fundamental therapeutic approaches, their postoperative morbidity and mortality rates have been reported to be up to 33% and 13%, respectively. Recent studies suggest that percutaneous transhepatic intervention is an effective and less invasive therapeutic modality compared with traditional surgical treatment. Compared with fluoroscopic intervention, percutaneous with cholangioscopy may be more useful in biliary strictures, as it can provide visual information regarding the stricture site. We recently experienced two cases complete membranous occlusion of the bilioenteric anastomosis and successfully treated both patients using percutaneous transhepatic cholangioscopy.

PURPOSE: We performed this study to evaluate the alterations in renal function for patients with ileal conduit and ileal orthotopic neobladder MATERIALS AND METHODS: From January 1999 to June 2004, 48 patients who had undergone radical cystectomy with urinary diversion were included in our study. The patients were divided into two groups according to the types of urinary diversion. One group consisted of 29 patients with ileal conduit and the other group consisted of 19 patients with ileal W neobladder. The mean age of the ileal conduit group and the ileal W neobladder group were 65.6+/-9.9 years and 60.8+/-8.3 years, respectively. The preoperative and postoperative blood urea nitrogen/creatinine (BUN/Cr) levels, postoperative complications and postoperative GFR, as measured by (99m)Tc-DTPA scans, were compared between the two groups. RESULTS: For the postoperative complications, stricture at the ureterovesical anastomosis site occurred in 1.7% (1/58 renal units) of the ileal conduit group and in 10.5% (4/38 renal units) of the ileal W neobladder group. Acute pyelonephritis occurred in 5.2% (3/58 renal units) of the ileal conduit group and in 5.3% (2/38 renal units) of the ileal W neobladder group. The pre- and postoperative serum BUN/Cr levels were 20.8/1.3 and 24.8/1.6, respectively, in the ileal conduit group, and 17.2/1.1 and 18.8/1.2, respectively, in the ileal W neobladder group. There were no statistical significant differences between the pre- and postoperative changes of the serum BUN/Cr levels for both groups. The GFR, as measured by (99m)Tc-DTPA scans, were 77.6 and 78.7ml/ min/1.73m2 in the ileal conduit group and the ileal W neobladder group, respectively. There were no statistical significant differences between the two groups. CONCLUSIONS: There were no significant differences in renal function between the ileal conduit and ileal W neobladder.

PURPOSE: The surgical treatment of anal stenosis includes internal sphincterotomy, rotaton flap and advancement flap according to the stenosis degree, recently, Christensen performed house shaped advancement flap and reported fair results. We compared and analyzed the surgical methods and results in patients with moderate and severe anal stenosis who underwent house shaped advancement flap and C-anoplasty. METHODS: We have performed this study with 6 cases using the house shaped advancement flap and 6 cases using the C-anoplasty. The out come was assessed by clinical characteristics, surgical method, operation time, duration of hospitalization, healing time, postoperative complications, results. RESULTS: The average operation time was 38 min in those house shaped advancement flap cases and 63 min in C-anoplasty cases. The average time of hospitalization was 6 days and 9 days, respectively, and the average time of healing was 28 days and 46 days, respectively. In those house advancement flap cases, surgery could be done in 2 directions at the same time in 4 cases and 3 directions in 2 cases; as for those C-anoplasty cases, surgery could be done in 1 direction in 4 cases and 2 directions in 1 case. Two complications were observed in C-anoplasty, one flap infection and one flap necrosis, and in house shaped advancement flap, no complication was observed. CONCLUSIONS: House shaped advancement flap have several advantages compared to the C-anoplasty, and since house shaped advancement flap could be performed in 2 to 3 directions or even 4 directions at the same time, the anus could sufficiently expanded in severe anal stenosis patients. The house shaped advancement flap might be one of the good method in treating anal stenosis.

Laparoscopic colorectal operation is one of the most reliable procedures and widely used in the treatment of gastrointestinal tumor. Its advantages, including minimed invasiveness and rapid postoperative recovery have been widely accepted, but the complications are still chanllenging for surgeons. Intraoperative complications mainly include vascular injury, bowel injury and ureteral damage. Postoperative complications include anastomotic leak, bleeding and stenosis. Understanding of anatomy and precise operation are critical to prevent complications. Diagnosis of postoperative complications in time and proper treatment can achieve maximal improvement of outcomes.

Central lung cancer is a common disease in clinic which usually occurs above the segmental bronchus. It is commonly accompanied by bronchial stenosis or obstruction, which can easily lead to atelectasis. Accurately distinguishing lung cancer from atelectasis is important for tumor staging, delineating the radiotherapy target area, and evaluating treatment efficacy. This article reviews domestic and foreign literatures on how to define the boundary between central lung cancer and atelectasis based on multimodal images, aiming to summarize the experiences and propose the prospects.

PURPOSE: There are a variety of open surgical and endoscopic methods to the treatment of urethral injuries. The objective of our study is to evaluate the efficacy of primary endoscopic urethral realignment according to the injury site. MATERIALS AND METHODS: Twenty eight patients with urethral injuries(23 anterior and 5 posterior) were treated by primary endoscopic urethral realignment from March 1990 to August 1997. According to the injury site, age distribution, etiology of injury, associated injuries, time to operation, operating time, duration of urethral Foley catheterization, maximal flow rate, postoperative complications and treatment of post-realignment stricture were reviewed. RESULTS: The age range of our patients was from 20 to 86 years(mean 45.0). Among the 28 patients, 23 were anterior and 5 were posterior urethral injuries. Pelvic bone fracture was associated in 1 patient(20.0%) in the anterior urethral injury group, while 5 patients(100%) in the posterior urethral injury group. The mean time after injury to realignment was 1.9 days (range 0 to 9) and the mean operating time was 53.9 minutes in the anterior urethral injury group(range 20-190) and 79.0 minutes in the posterior urethral injury group(range 25-170). The mean duration of urethral Foley catheterization was 24.5 days in the anterior urethral injury group and 61.4 days in the posterior urethral injury group. The mean maximal flow rate after catheter removal was 31.4ml/sec in the anterior urethral injury group and 24.6ml/sec in the posterior urethral injury group. Of the 23 patients, 9 patients(39.1%) had post-realignment strictures in the anterior urethral injury group and 8 were treated with visual urethrotomy, and only one patient was required open urethroplasty. Of the 5 patients, 4 patients(80.0%) had post-realignment strictures in the posterior urethral injury group and treated with visual urethrotomy. CONCLUSIONS: Primary endoscopic urethral realignment is a safe and simple technique with minimal mobidity regardless of injury site. The stricture formation, impotence and incontinence rates of this technique are comparable to those reported for open surgical methods. Finally, most post-realignment strictures can be treated successfully with visual internal urethrotomy with or without occasional sound dilation.

PURPOSE: The developments and advances in extracorporeal shock wave lithotripsy and endourological procedures have greatly diminished the need for open surgery in the treatment of renal and ureteral stones. We reviewed our experience of open stone surgery to determine current indications and efficacy of this treatment modality. MATERIALS AND METHODS: We undertook a review of hospital and office charts, operative records, and pertinent radiographic studies of all patients that had undergone open stone surgery from May 1986 to June 2001 at a single tertiary university hospital. Of 5,533 procedures performed for stone removal, 355 were open surgical procedures (6.4%), these included ureterolithotomy in 215 (60.6%), pyelolithotomy in 50 (14.1%), anatrophic nephrolithotomy in 43 (12.1%), and nephrectomy in 47 (13.2%). RESULTS: The indications for open surgery were complex stone burden (61%), failure of extracorporeal shock wave lithotripsy or endourological treatment (9%), other co- operation (10.4%) and anatomical abnormalities, such as: ureteropelvic junction obstruction, infundibular stenosis and/or renal caliceal diverticulum (6.5%). Stone free rate, following surgery, was 90.7%. All patients had minor postoperative complications that were resolved with appropriate therapy. CONCLUSIONS: Open stone surgery continues to be a reasonable alternative modality for a small proportion of patients with urinary stones. Those patients with large urinary stone, failed less invasive method, anatomical abnormality and serious medical diseases would be recommended for open stone surgical correction.
