ABSTRACT
Objective:To compare the efficacy of pneumovesicoscopic Cohen and Politano-Leadbetter procedures in the treatment of vesicoureteral junction obstruction (VUJO) in children.Methods:The data of 48 children with VUJO who underwent operations in the Department of Urology, Anhui Provincial Children′s Hospital from January 2017 to December 2021 were retrospectively analyzed.According to the operation time, the patients were divided into the pneumovesicoscopic Cohen group(group C) (28 cases) and pneumovesicoscopic Politano-Leadbetter group(group P) (20 cases). The operation time, postoperative urinary catheterization duration, hematuria duration, hospitalization time, and the improvement of hydronephrosis, ureteral dilatation, and renal function after surgery were compared between the 2 groups.The enumeration data were compared by the χ2 test or Fisher′ s exact probability method.The measurement data were compared by the t-test. Results:All the 48 children were successfully operated on by the same surgeon, without conversion to open surgery.Six cases in the group C had a megaureter and underwent ureter tailoring.Two cases in the group P had calyceal and ureteral calculi, which were all removed after operation.There was a statistically significant difference in the operation time between group C and group P[(136.5±35.4) min vs.(165.8±33.2) min, t=-3.154, P=0.002]. The patients were followed up for (10.3±2.6) months after operation.There were 8 cases and 6 cases of urinary tract infection in group C and group P within 2 months after the operation, respectively.They all improved after conservative anti-infection treatment, and the infection was well controlled after removal of the D-J tube.Besides, their intravenous pyelography 6 months after operation showed that the ureter was unobstructed.In group C, 6 months after the operation, the anterior and posterior diameters of the renal pelvis [(1.62±0.54) cm vs.(2.55±1.24) cm, t=-5.027, P=0.001] and the largest diameter of the ureter [(0.95±0.27) cm vs.(1.51±0.52) cm, t=-8.495, P<0.001] were significantly decreased, compared with those before operation.However, the renal cortex thickness was increased significantly [(1.47±0.25) cm vs.(0.86±0.46) cm, t=2.028, P=0.004], and the renal function (as indicated by the diuretic nephrogram) was notably improved [(46.27±2.16)% vs.(41.83±3.04)%, t=1.647, P=0.030]. In group P, 6 months after operation, the anterior and posterior diameters of the renal pelvis[(1.48±0.82) cm vs.(2.68±1.41) cm, t=-2.740, P=0.003] and the maximum diameter of the ureter [(1.05±0.46) cm vs.(1.36±0.27) cm, t=-1.635, P=0.040] were significantly smaller than those before operation.However, the renal cortical thickness was increased [(1.38±0.33) cm vs.(0.74±0.39) cm, t=9.073, P<0.001], and the renal function (as indicated by the diuretic nephrogram) was significantly improved [(45.18±3.35)% vs.(39.55±2.49)%, t=1.277, P=0.030]. Politano-Leadbetter surgery outperformed Cohen surgery in promoting the recovery of the anterior and posterior diameters of the renal pelvis [(1.48±0.82) cm vs.(1.62±0.54) cm, t=-1.748, P=0.030]. Conclusions:Pneumovesicoscopic Politano-Leadbetter operation can establish a longer submucosal tunnel without changing the ureteral shape and opening position, having good effects in treating VUJO combined with calyceal and ureteral calculi.Pneumovesicoscopic Politano-Leadbetter operation can also better improve postoperative recovery from hydronephrosis than Cohen operation.However, the pneumovesicoscopic Politano-Leadbetter operation is more difficult and requires longer time.The surgeon should choose a reasonable operation based on his/her own experience.
ABSTRACT
@#Distal ureteral injury is a rare complication of laparoscopic radical prostatectomy (LRP). The authorsreport such a case which was repaired successfully with an exclusively laparoscopic approach. Theyalso describe the advantages of the flank position when performing this minimally invasive approach.@*THE CASE@# 61-year-old Filipino male, with a PSA of 10 ng/cc, diagnosed with localized prostatecancer undergoes LRP, utilizing a posterior approach to the seminal vesicles. Intraoperatively, alarge intravesical median lobe was noted which was dissected meticulously after the division of thebladder neck. The excision of the 60gm prostate was completed in the conventional manner followedby a urethrovesical anastomosis. Blood loss was minimal with no apparent intraoperative events.Histopathology confirmed prostate cancer, Gleason score (4+3) with negative margins. Postoperatively,he had progressively high pelvic drain output and noticeably a relatively low urethral catheter output.CT urogram done on POD 8 showed a distal left ureteral disruption with intraabdominal extravasation.The authors performed a laparoscopic left ureteroneocystostomy on POD 9. The patient did wellafter the repair. After removing the indwelling catheter on postoperative day 14, he was dischargedin a good clinical condition. The ureteral stent was removed one month after the reimplantation.Follow-up CT urogram showed unobstructed flow through the reimplanted left ureter. Follow-upPSA at this time was 0.01ng/cc.@*CONCLUSION@#Ureteral injury following LRP is a devastating complication which may go undiagnosedintraoperatively. Prompt recognition, followed by a timely minimally invasive repair through alaparoscopic approach is needed to correct this problem.
ABSTRACT
Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.
ABSTRACT
Objective:To evaluate the therapeutic characteristics of laparoscopic repair in children with ure-terovesical junction malformation through internal or external bladder.Methods:From February 2018 to August 2019, 29 cases of hydronephrosis combined with ureter expansion treated in the First Affiliated Hospital of Zhengzhou University, with 17 boys and 12 girls confirmed through the preoperative examinations.Inspection results revealed 15 cases of ureteropelvic junction obstruction, 12 cases of vesicoureteral reflux, and 2 cases of single ectopic ureter.Totally, 21 cases were treated by pneumovesical laparoscopic Cohen means, including 17 unilateral cases and 4 bilateral cases, 5 cases of ureterocele, and 8 cases of ureteral clipping.A total of 8 cases were treated by laparoscopic Lich -Gregoir surgical treatment, including 7 unilateral cases and 1 bilateral case.Meanwhile, 4 cases of ureteral clipping were performed among them.There was 1 case of duplex kidney with the ectopic upper ureter outside iliac blood vessels, 1 case of bilateral cryptorchidism and 1 case of unilateral cryptorchidism.Ureteral stents were implanted for those with ureteral tailoring.The catheters were removed 7 days after operation, and the indwelling ureteral stents were removed by cystoscope under general anesthesia after about 6 weeks.Results:All the cases with hydronephrosis and ureteral dilatation were completed in laparoscopic surgery, without open surgery or blood transfusion, 21 cases were treated by pneumovesical laparoscopic Cohen means, with the average time being 1.8 hours in unilateral side and 2.8 hours in bilateral sides.At the same time, 8 cases were treated by laparoscopic Lich-Gregoir means, with the unilateral average time being 1.7 hours and bilateral time being 3.0 hours.All cases were followed up at an average month of 9 (4-20 months), and all children underwent voiding cystourethrography 4 months after the operations.The voiding cystourethrogram(VCUG) of all the cases was confirmed successfully, with only 1 case of vesicoureteral reflux in level Ⅲ, and their hydronephrosis were relieved.There was no vesicoureteral reflux in the others.The short-term urinary retention occurred in 1 patient with bilateral ureteral reimplantation in Lich-Gregoir group, and the symptom disappeared after 1 week of indwelling catheterization.Among them, 1 patient in Cohen group had hematuria that disappeared gradually for 4 days after surgery.There were no significant differences in operation time and postoperative recovery between the two groups.The length of hospital stay in laparoscopic Lich -Gregoir group was slightly longer than that in pneumovesical laparoscopic Cohen group.Conclusions:As for children with ureterovesical junction malformation, laparoscopic Lich-Gregoir surgery is suitable for the ectopia of ureter opening, overexpansion of ureter, and other abdominal malformation complicated and expansive ureter without tortuosity.Pneumovesical laparoscopic Cohen surgery is suitable for hydronephrosis and ureteral expansion with ureterocele, especially with the symptom of dysuria, and ureteral tortuosity obviously.The two ways are safe and reliable, and the advantages and disadvantages should be weighed before being chosen.
ABSTRACT
This study aims to report the technique of partial cystectomy and bilateral ureteral reimplantation for resection of transitional cell carcinoma (TCC) in the trigone region of the bladder and the long-term follow-up in a Bernesse Mountain dog. The proposed surgical technique was considered viable and a potential treatment option for TCC in bladder trigone, with benefits regarding the prevention of urinary tract obstruction due to neoplastic growth and local removal of the primary tumor, which may limit or delay the spread of the disease even without adjuvant chemotherapy. The main disadvantages related to the described technique are ureteral stricture, intermittent cystitis and local relapse. However, the results are acceptable considering the long-term survival of 610 days in the case described.(AU)

BACKGROUND AND OBJECTIVES: Ureteral Reimplant is commonly used in pediatric and gyne-cologic surgery. Most techniques demand an experienced surgeon and lasts 2-3 hours. There is no consensus about the preferred technique until today. We report a simple modification of the Taguchi to reduce duration and make it more suitable for laparoscopic approach. METHOD: Three patients underwent distal ureteral reimplant, based on our modified Taguchi minimally invasive approach technique. Cystography and ultrasonography were performed on the 30th, 90th and 180th postoperative days to monitor kidneys; a one-year follow-up for recurrence or clinical symptoms was also performed. RESULTS: Operative time for ureteral reimplant using our technique was 15-25 minutes. The results of the performed exams on postoperative days showed normal kidneys without hydro-nephrosis. At the one-year follow-up no signs of recurrence or clinical symptoms were present. CONCLUSION: Our modifications allowed a faster and easier management of distal ureteral reimplant, with excellent perioperative and post-operative outcomes. To our knowledge this is the first detailed description of this technique through minimally invasive approach. However, further studies and a longer follow up will be necessaries to confirm the long-term outcomes and clinical benefits of our technical proposal.
JUSTIFICATIVA E OBJETIVOS: O reimplante ureteral é comumente utilizado em cirurgia pediátrica e ginecológica. A maioria das técnicas exigem um cirurgião experiente e dura 2-3 horas. Não há consenso sobre a técnica preferida até hoje. Relatamos uma modificação simples do Taguchi para reduzir sua duração e torná-lo mais adequado para a abordagem laparoscópica. MÉTODO: Três pacientes foram submetidos a reimplante ureteral distal, com base na técnica de abordagem minimamente invasiva de Taguchi modificada. Cistografia e ultra-sonografia foram realizadas no 30º, 90º e 180º dias de pós-operatório para monitorização dos rins; um acompanhamento de um ano para recorrência ou sintomas clínicos também foi realizado. RESULTADOS: O tempo operatório para o reimplante ureteral utilizando a nossa técnica foi de 15-25 minutos. Os resultados dos exames realizados nos dias pós-operatórios mostraram rins normais sem hidronefrose. No seguimento de um ano não houve sinais de recorrência ou sintomas clínicos. CONCLUSÃO: Nossas modificações permitiram um manejo mais rápido e fácil do reimplante ureteral distal, com excelentes resultados peri- e pós-operatórios. Tanto quanto sabemos, esta é a primeira descrição detalhada desta técnica através de abordagem minimamente invasiva. No entanto, estudos adicionais e um acompanhamento mais longo serão necessários para confirmar os resultados a longo prazo e os benefícios clínicos da técnica proposta.

ABSTRACT
Antecedentes y Objetivos: La práctica de la colocación de stent en la anastomosis ureteral en trasplante es controvertido. Los beneficios del stent incluyen: descompresión continua del uréter con menor tensión anastomótica y alineamiento ureteral que protege de la obstrucción. Las desventajas: infección urinaria, obstrucción a largo plazo de la unión ureterovesical, hematuria por erosión mucosa y el retiro del mismo bajo sedación por vía endoscópica. Es nuestro objetivo investigar la incidencia de complicaciones con la utilización de stent ureteral vs. tutor ureteral en el trasplante renal pediátrico. Material y Métodos: Valoración retrospectiva de pacientes trasplantados renales en nuestra institución con técnica de Lich-Gregoir en el implante ureteral en el período febrero 2008 a marzo 2014. Dos grupos de pacientes para investigar complicaciones: aquellos con tutor ureteral por período de 5 dias vs. los pacientes en los que se utilizó catéter doble jota (stent) por período de 30 días. Se identificaron los pacientes con uropatía y nefropatía como causa de insuficiencia renal crónica terminal (IRCT) y se asociaron a las complicaciones que fueron divididas en no infecciosas (urológicas) y en infecciosas (infección urinaria). Resultados: Se evaluaron 183 pacientes. En el grupo con tutor ureteral (n=68) se presentaron complicaciones urológicas en 8 pacientes (11.76%), 2 urópatas y 6 nefrópatas y las complicaciones infecciosas se observaron en 15 pacientes (22.06%). En el grupo stent (n=115) se presentaron complicaciones urológicas en 3 casos (2,61%), 2 urópatas y un nefrópata y las complicaciones infecciosas se observaron en 43 pacientes (37.39%). Conclusiones: La asociación de la técnica de Lich Gregoir con stent mejora la morbilidad evitando complicaciones no infecciosas, pero aumenta la incidencia de complicaciones infecciosas independiente del origen de la causa de la IRCT (AU)
Background and aims: Stent placement in ureteral anastomosis is controversial. Benefits of the stent include: continuous decompression of the ureter with less anastomotic tension and ureteral alignment with better protection from ureteral narrowing. Disadvantages: urinary infection, long-term stricture of the vesicoureteral junction, hematuria due to mucosal erosion and its endoscopic removal under sedation. Our aim was to assess the incidence of complications of the use of a ureteral stent vs. ureteral splint in pediatric kidney transplantation. Material and methods: Retrospective assessment of kidney transplant patients in whom the Lich-Gregoir technique was used for ureteral implantation between February 2008 and March 2014. Two groups of patients were selected to assess complications: Patients with a ureteral splint for 5 days vs. patients in whom a double J catheter (stent) was used for 30 days. Patients with uropathy and nephropathy due to end-stage chronic renal failure (ESRD) were identified and associated complications were divided into non-infectious (urological) and infectious (urinary infection) complications. Results: 183 patients were evaluated. In the ureteral splint group (n=68), urological complications were observed in 8 patients (11.76%), 2 uropathic and 6 nephropathic, and infectious complications were observed in 15 patients (22.06%). In the stent group (n=115), urological complications were observed in 3 cases (2.61%), 2 uropathic and 1 nephropathic, and infectious complications were seen in 43 patients (37.39%). Conclusions: The association of the Lich Gregoir technique with stent placement improves morbidity avoiding non-infectious complications, but increases the incidence of infectious complications regardless of the cause of ESRD (AU)

Objective To assess the outcome of vesicoureteral reflux after augmentation cystoplasty in patients with neurogenic bladder.Methods Between January 2008 and January 2014,a total of 25 patients,with a hypocompliant bladder associated with vesicoureteral reflux confirmed by video-urodynamics preoperatively,were recruited in this study.They all had undergone bladder augmentation with a generous detubularized segment of bowel at our institution.No effort had been made to correct existing reflux.Preoperatively assessment included urinalysis,kidney function tests,ultrasonography,video-urodynamic evaluation.All patients had various degrees of vesicoureteral reflux.The status of vesicoureteral reflux and bladder function were studied by video-urodynamic.Results Mean follow-up was 2.2 years (range 0.5 to 5.5 years).The video-urodynamics manifested a significant improvement of bladder capacity,diminution of intravesical pressure and resolution of reflux after bladder augmentation.Of the 25 patients,20 (80％) no longer had reflux,3 (12％) had improvement,2 (8％) had no change.Sixteen of 18 with grades Ⅰ to Ⅲ (89％),all refluxing units with grade Ⅳ to grade Ⅴ (100％) showed complete cessation of reflux.Symptomatic urinary infection was not found after surgery.Conclusions Augmentation enterocystoplasty without ureteral reimplantation is effective and adequate for patients with high pressure and hypocompliant neurogenic bladder.Therefore,ureteral reimplantation is not necessary underwent when augmentation enterocystoplasty is recommended to patients with neurogenic bladder and vesicoureteral reflux.
ABSTRACT
PURPOSE: We review our experience using a new and easily removable ureteral catheter in patients who underwent complicated ureteral reimplantation. Our goal was to shorten hospital stay and lower anxiety during catheter removal without fear of postoperative ureteral obstruction. MATERIALS AND METHODS: Between April 2009 and September 2010, nine patients who underwent our new method of catheter removal after ureteral reimplantation were enrolled. Patients who underwent simple ureteral reimplantation were excluded from the study. Following ureteral reimplantation, a combined drainage system consisting of a suprapubic cystostomy catheter and a ureteral catheter was installed. Proximal external tubing was clamped with a Hem-o-lok clamp and the rest of the external tubing was eliminated. Data concerning the age and sex of each patient, reason for operation, method of ureteral reimplantation, and postoperative parameters such as length of hospital stay and complications were recorded. RESULTS: Of the nine patients, four had refluxing megaureter, four had a solitary or non-functional contralateral kidney and one had ureteral stricture due to a previous anti-reflux operation. The catheter was removed at postoperative week one. The mean postoperative hospital stay was 2.4 days (range 1-4 days), and the mean follow-up was 9.8 months. None of the patients had postoperative ureteral obstructions, and there were no cases of migration or dislodgement of the catheter. CONCLUSION: Our new method for removing the ureteral catheter would shorten hospital stays and lower levels of anxiety when removing ureteral catheters in patients with a high risk of postoperative ureteral obstruction.

La endometriosis ureteral es una infrecuente localización de endometriosis profunda, que puede condicionar una grave disminución de la función renal de forma silenciosa. Se presenta el caso de una paciente con fibrosis peritoneal secundaria a endometriosis profunda, cuya inespecífica sintomatologia conllevó un retraso diagnóstico, permitiendo el desarrollo de hidronefrosis. Es necesario descartar la presencia de endometriosis profunda en mujeres en edad fértil con hidronefrosis de etiología desconocida.
Deep endometriosis rarely entails ureteral involvement. It may be responsible of asymptomatic loss of renal function. A 35-year-old woman, gravida 1, para 1, was managed for peritoneal fibrosis due to deep infiltrating endometriosis. The nonspecific symptoms let a delayed diagnosis and a subsequent hydronephrosis. It must be excluded the existence of deep endometriosis in women of childbearing age with hydronephrosis of unknown etiology.

Objective To compare the clinical results of the ureteral reimplantation with the traditional open approach and laparcocopic pneumovesical approach. Methods A retrospective review of 108 patients who underwent ureteral reimplantation from December 2004 to October 2010 was conducted.The patients were divided into open and pneumovesical groups according to the surgical approach.Perioperative results were compared between the two groups in terms of operative time,postoperative intravenous antibiotics duration,catheterization duration,postoperative stay,average total cost and surgical cost,respectively.And the pneumovesical group was divided into two stages by time,compared the operative time of the two stages and between the later stage and the open group. Results The postoperative hospital stay of pneumovesical group was shorter than the open group (6.8 ± 1.9 d and 8.9 ± 2.9 d,P =0.002 ).For catheterization duration,the pneumovesical group was shorter than the open group as well (5.2 ± 1.2 d and 6.2 ±2.2 d,P=0.057).For the postoperative intravenous antibiotics duration,the pneumovesical group was 5.0 ± 1.3 h,the open group was 5.4 ±1.6 h (P =0.159).For the total cost,the pneumovesical group was 16 067.9 ±4 295.8 RMB,the open group was 15 617.7 ± 5 486.5 R MB (P =0.168).For the surgical cost,the pneumovesical group was 9369.4 ± 1366.6 RMB,the open group was 7397.9 ± 1797.3 RMB ( P =0.083 ).Operative duration of the pneumovesical group and open group were 3.2 ± 1.1 h and 2.3 ± 1.1 h ( P =0.003).For pneumovesical group,the mean operative durations of the two stages were 3.6 h and 2.8 h (P =0.286).And the later stage of pneumovesical group was a little longer than the open group,but no significant difference ( P =0.234 ).No major complication was found in the 2 groups during the operative time and the postoperative hospital stay.Twenty-four patients (38 ureters) of the pneumovesical group were followed up with micturating cystourethrography ( MCU),ureterovesical reflux recurred in 3 patients.Two patients changed from grade Ⅲ to grade Ⅰ and 1 patient changed from grade Ⅴ to grade Ⅲ after the surgery.Five patients (9 ureters) of the open group were followed up,1 patient found bladder diverticulum; 1 patient found ureteral stricture 6 months after the surgery and got improved after secondary ureteral relimplantation surgery. Conclusions The pneumovesical approach is shorter than the open group in postoperative hospital stay and catheterization reserved duration.The pneumovesical approach is a safe and effective option for ureteral reimplantation.
ABSTRACT
Objective To assess clinical and urodynamic results of augmentation enterocystoplasty (AE) in patients with ncurogcnic hladdcr dysfunction (NBD).Methods Retrospectively reviewed our database between 2005-2011 to identify 77 patients who underwent AE ( sigmoid 74 patients,ileum 3 patients).Postoperativc complications,renal function,urodynamics parameters and quality of daily life were evaluated.Results The mean follow-up length was 24 months.Compared with pre-operative condition,the mean bladder capacity significantly increased from (160.6 ± 128.3) to (468.5 ± 60.6) ml (P ＜0.001 ) and the maximum detrusor pressure decreased from ( 31.1 ± 26.4) to ( 10.9 ± 4.5 ) cm H2O ( P =0.002 ).Serum creatinine level decreased from (270.3 ± 113.6 ) to ( 174.4 ± 81.3 ) μmol/(l) ( P =0.00 1 ).There were significant decrease on mean number of incontinence episodes and pads used per day ( P ＜0.01 ).Post-operative complications included metabolic acidosis in two patients (2.6％),adhesive intestinal obstruction in four patients (5.2％),deteriorating renal function in one patients ( 1.2％ ) and recurrence of vesicoureteral reflux in three patients (3.9％).Conclusions The results suggest that AE is safe and effective in treating patients with NBD.Concomitant URI is considerèd on patients with long illness history,vesicoureteral reflux at low intravesical pressures and upper urinary tract dilation.Patients with moderate and severe upper urinary tract deteriorations benefit from this procedure and the benefit can maintain a long time.
ABSTRACT
Objective To present the preliminary experience with laparoscopic ureteral reimp1ant for distal ureteral stricture without everted ureteral nipple or submucosal tunneling. Methods Six patients with distal ureteral stricture underwent transperitoneal laparoscopic ureteral reimplantation.The ureteral was reimplanted into the bladder without everting the ureter or without a tunnel.The seromuscular wall of the ureter was anastomosed eircumferentially to the bladder muscle layer by continuous suture. Results All procedures were successfully performed without any intraoperative complications or need for open conversion.Intravenous urography showed normal drainage without obstruction or reflux during follow-up. Conclusion Laparoscopic ureteral reimplantation might be technically simple and feasible.
ABSTRACT
We reviewed medical records of 32 children with vesicoureteral reflux who underwent ureteral reimplantation by Cohen technique. Between January 1990 and December 1993, 21 patients were managed with ureteral catheters and suprapubic tubes during the initial postoperative period (group A), whereas between January 1994 and June 1995, 11 consecutive patients were managed with "catheterless" technique employing none of these devices (group B). The mean age was 39.7 months, the male to female ratio was 24:8 and the mean follow-up period was 13.1 months. The mean length of hospital stay was 10.2 days for group A and 7.2 days for group B (p=0.001). The mean day of pain medication was 8.9 days for group A and 6.0 days for group B (p=0.011) The mean number of pain medication was 35.6 times for group A and 24.0 times for group B (p> 0.05). This represents a 32.6% decrease in the mean number of pain medication for group B, despite of the statistical insignificance. There was neither complication nor failure for group B. In conclusion, we believe that the catheter-free ureteral reimplantation provides a safe and reliable alternative which may results in less morbidity than traditional methods in children.

Surgical results of 34 children (68 ureters) who underwent Cohen ureteral reimplantation in the last 6 years were evaluated. All children were followed at least 4 months after the operation. Indication for the repair consisted of vesicoureteral reflux in 22 children, obstructive megaureter in 8 children and ureterocele in 4 children. The underlying problems in 55 ureters ( 94.8% ) were successfully corrected. Surgical failures were persistent reflux in 2 ureters, new ipsilateral reflux in 1 ureter and contralateral reflux in 1 ureter. However, no ureteral obstruction was noticed in this series. In conclusion, the Cohen cross trigonal technique was a safe and effective method of ureteral reimplantation in children.

Ureteral reimplantation has been used widely for the correction of ureterovesical reflux, terminal ureteral stricture, ureteral obstruction, ectopic ureteral opening, megaureter, renal transplantation and ureteral injury, etc. The ultimate purpose of the ureteral reimplantation is for the preservation of renal function and upper urinary tract. since the concept of ureterovesical reflux reported by Sampson in 1903, many types of surgical procedure of ureteral eimplantation have been developed and performed for various ureteral obstructive problems. There is also increasing tendency of ureteral reimplantation in out country. To determine the efficacy of ureteral reimplantation, we reviewed and evaluated the records of 34 patients(40 ureters) who underwent ureteral reimplantation at the Department of Urology, Seoul National University Hospital during the period from March, 1979 to February, 1983. And following results were obtained: 1. Ureteral reimplantation was performed in cases of ureterovesical reflux, ureteral stricture, megaureter, bladder tumor, failed previous reimplantation and surgical injury. 2. Thirty two ureters were reimplanted with the method of Politano-Leadbetter, five ureters with Glenn Anderson, one ureter with Cohen and one ureter with transureteroureterostomy with Boari-flap method. 3. Mean duration of ureteral stenting was 6 days(3-10 days). 4. Complications had been observed in 11 cases which included persistent pyuria, persistent reflux, acute pyelonephritis, paralytic ileus, vesicocutaneous fistula and obstruction. 5. Postoperative pyelographic appearances were improved in 10/13(76.9%) cases. We made a conservative treatment in patients with persistent urinary tract infection.
