A “bridge” technique to replace the obstructed single-J stent in the patient with ileal conduit urinary diversion: a case report

The ureteroileal anastomotic stricture is a complication of ileal conduit urinary diversion. To prevent the hydronephrosis and protect the renal function, a single-J ureteral stent may be needed. However, the most common complication of these patients is single-J stent obstruction. To solve this problem, we describe an easy, useful and low-cost technique to replace the obstructed ureteral stent under radiographic guidance without intervention by flexible cystoscopy or percutaneous nephrostomy. The key steps of our procedure are to identify the location of the stricture, to place the super smooth guide wire into pinhole of the obstructed single-J stent and to get the super smooth guide wire and 5-Fr ureteral catheter across the stricture. Our case was a 40-year-old male patient who was diagnosed as pelvic lipomatosis and received ileal conduit urinary diversion 3 years ago. The left-side ureteroileal anastomotic stricture occurred 1 year after surgery. He refused to repair the stricture by open or other minimal invasive surgery. He regularly changed his ureteral stent with intervals of three months. As the stent was obstructed by the stone, the guide wire couldn’t be inserted through the primary ureteral stent. We used our “bridge” technique to solve his problem successfully. No bleeding and no urinary tract infection were observed after intervention. The urine from the ureteral stent was fluent. We think that this “bridge” technique may be a good choice for the replacement of the obstructed single-J stent in the patients of ileal conduit urinary diversion.     

Bricker's ileal conduit urinary diversion with a simple non-refluxing uretero ileal anastomosis

Fifty consecutive patients had ileal conduits constructed with a technically and quick simple antireflux ureteroileal anastomosis. Complications related to the ureteral implantation were studied retrospectively, and at follow-up (8 months-12 years later, median 3 years) conduit dysfunction and ureteral reflux were assessed in 18 patients out of the 25 patients who were still alive. Early complications and signs of late upper urinary tract deterioration were similar to those found after other operative techniques had been used. One patient had a postoperative urinary leak from the uretero ileal anastomosis. which was treated successfully by two weeks drainage. Hydronephrosis deteriorated in 18 (26%) of the renal units, remained unchanged in 39 (57%) and improved in 11 (16%). Increases in plasma creatinine concentrations up to 200 mumol/l were found in eight patients, and in one patient it increased from 300 to 420 mumol/l. Partial ureteral reflux was present in three (2 patients) of 33 ureters studied and minimal conduit dysfunction was found in 8 patients. In conclusion we find this method of urinary diversion to be quick, easy, and safe.     

Urinary fistula into ureteral stump after ileal conduit diversion

Despite ileal conduit diversion for urinary incontinence, an adolescent male with meningomyelocele continued to void per urethram postoperatively. Urologic investigation disclosed spontaneous fistulization from a ureteroileal anastomosis to a ligated ureteral stump, with resultant urinary drainage to the bladder. This unusual complication of ileal conduit diversion has not been reported previously. More attention should be directed to securing a watertight ureteroileal anastomosis. A careful single layer anastomosis is recommended to minimize urinary leakage without increasing the risks of stenosis and obstruction.     

Laparoscopic ileal conduit: five-year follow-up

OBJECTIVES: To report the techniques used for intracorporeal laparoscopic construction of an ileal conduit urinary diversion and long-term patient follow-up after this procedure. METHODS: A 28-year-old man with cerebral palsy, a neurogenic bladder, and voiding dysfunction was referred for definitive management of his urinary tract after several episodes of pyelonephritis. A conduit urinary diversion was performed using a 5-port, transabdominal approach. An appropriate length of ileum was used for diversion, and ureterointestinal anastomoses were performed using a modified Bricker technique. All aspects of the procedure were performed intracorporeally, including isolation of conduit, bowel reanastomosis, ureteral mobilization, and ureterointestinal anastomosis. A 12-mm port site was enlarged and used as the stoma, which was constructed in routine fashion. RESULTS: Five years after surgery, this patient had normal and stable renal function, with a serum creatinine of 0.8 mg/dL. Serial imaging studies continued to reveal prompt and symmetric renal function and no evidence of obstruction or reflux. CONCLUSIONS: Laparoscopic ileal conduit construction is feasible and can provide durable results. Although technically challenging, ongoing technical refinements will make performance of reconstructive laparoscopy more widely applicable. Larger series with substantial follow-up will help illuminate the place of laparoscopic noncontinent urinary diversion in the surgical armamentarium.     

Recurrence of transitional cell carcinoma in the left pelvis and ureter, and ileal conduit after total cystectomy: a case report

A 63-year-old male with transitional cell carcinoma of the bladder underwent total cystectomy. Five years later sequential excretory urography and urinary cytologic examination revealed tumor recurrence in the left pelvis and ureter; left nephroureterectomy was performed in July, 1984. In December, 1985, he complained of macrohematuria and urinary cytology was positive. Ileal conduitgraphy showed filling defects at the bilateral uretero-ileal anastomosis, where two papillary lesions were disclosed by endoscopic examination. In January, 1986, total extirpation of the ileal conduit and reconstruction of a new ileal conduit was performed. Macroscopically the two lesions were found to be a papillary tumor at left uretero-ileal anastomosis and a polypoid tumor distal to right uretero-ileal anastomosis. Histological examination revealed both tumors to be grade II transitional cell carcinoma. This rare case is discussed and the literature is reviewed.     

Case report: Laparoscopy-assisted urinary undiversion: transforming an ileal conduit into an orthotopic continent neobladder

PURPOSE: To describe the technique of laparoscopy-assisted undiversion of an ileal conduit into a continent orthotopic ileal neobladder performed on a patient with a previous radical cystoprostatectomy and ileal conduit. CASE REPORT: A 57-year-old man presented with a prolapsed stoma and a history of a right radical nephroureterectomy for grade 3 ureteral transitional-cell carcinoma and a radical cystoprostatectomy and ileal conduit urinary diversion for in-situ bladder carcinoma, performed 12 and 8 years ago, respectively. After the ileal stoma was resected, five trocars were placed transperitoneally. Partial resection of the distal ileal conduit was performed, leaving in place the proximal segment with its left ureteroileal anastomosis. Flexible urethroscopy revealed a contracting external sphincter, and random urethral frozen-section biopsies ruled out tumor. A 45-cm segment of ileum was isolated and exteriorized through the stoma site, and an ileal neobladder was created extracorporeally, suturing the proximal ileal-conduit segment, with its ureteroileal anastomosis, to it. The ileal neobladder was reintroduced into the abdomen and anastomosed laparoscopically to the urethral stump with six 2-0 polyglactin sutures. The total operative time was 7 hours with a blood loss of 100 mL. There were no intraoperative complications. The hospital stay was 7 days. At a follow-up of 24 months, the patient had total daytime continence and normal renal function, and intravenous urography revealed an unobstructed urinary tract. CONCLUSION: Laparoscopy-assisted ileal-conduit undiversion into an orthotopic ileal neobladder is technically feasible. It can be considered an alternative to open surgery for patients who have undergone urinary diversion.     

Robot-assisted Bricker ileoureteral anastomosis during intracorporeal laparoscopic ileal conduit urinary diversion for prostatocutaneous fistula: case report

BACKGROUND AND PURPOSE: The da Vinci robot is useful during minimally invasive surgery in performing intracorporeal suturing. We report one case of its application during laparoscopic ileal conduit urinary diversion for prostatocutaneous fistula. METHODS: A 58-year-old paraplegic man with a neurogenic bladder and bowel and a long history of urinary incontinence developed a prostatocutaneous fistula after numerous procedures to correct the incontinence. He underwent laparoscopic ileal conduit urinary diversion to improve his quality of life. The da Vinci robot was used to perform the ileoureteral anastomosis. RESULTS: The operative time was 10 hours. The estimated blood loss was <100 mL. There were no intraoperative complications. The patient was started on a clear liquid diet on postoperative day 3. There was no narcotic use because of the patient's neurologic status. The patient was discharged home on day 6. CONCLUSION: Laparoscopic urinary diversion remains a technically challenging procedure. The da Vinci robot is useful during laparoscopic ileal conduit construction.     

The anterior ileal conduit: results of 100 consecutive cases

PURPOSE: The ileal conduit of Bricker is still widely used for urinary diversion after radical cystectomy for bladder carcinoma. We have modified the standard technique with the aim of reducing the complication rate and facilitating treatment. MATERIALS AND METHODS: We leave the conduit in its natural isoperistaltic anterior position, the ureters are anastomosed in an anterior position on their own side, using a short ileum segment. The incision of the peritoneum is made in a particular manner to allow on its closure to extraperitonealize the anastomoses and the bottom of the conduit and to support and fasten the loop. RESULTS: A total of 100 consecutive patients after radical cystectomy for bladder cancer had anterior ileal conduit. The complication rates were 5% temporary ureteroileal leakage, 1% reoperation rate, 5% long-term stenoses and 3% renal function deterioration. The surgical revision and the treatment of ureteroileal stenoses with anterograde percutaneous ureteral stenting were not complicated procedures. A comparison with conventional Bricker series shows a significant decrease in the complication rate. CONCLUSIONS: The anterior ileal conduit reduces the technique complication rate and facilitates the treatment of complications, and it is a recommended operation for these reasons.

A case of late recurrence of urothelial carcinoma in an ileal conduit after radical cystectomy and ileal conduit diversion for bladder cancer

Recurrence of urothelial cancer in an ileal conduit after radical cystectomy is rare. A 79-year-old man suffered bladder cancer (UC cTisN0M0 G2＞3) and underwent total cystectomy with ileal conduit. He had recurrence of the right renal pelvis carcinoma 6 years after the total cystectomy, and was treated by right radical nephroureterectomy (pT3 G2＝3). The patient had another episode of recurrence in the ileal conduit 13 years after the initial operation. The entire ileal conduit (UC, G3, ew (-)) was resected and left cutaneous ureterostomy was performed. This case suggests that long-term follow-up is necessary after radical cystectomy and ileal conduit for urinary diversion.     

A simple technique to change an obstructed ureteral stent in patients with an ileal conduit

PURPOSE: We describe a simple technique to replace an obstructed ureteral stent in patients with an ileal conduit and ureteral stenosis. MATERIALS AND METHODS: Our study included 4 patients with an ileal conduit and ureteral stenosis. A total of 10 obstructed ureteral stents were replaced with a new stent using this simple technique under radiographic guidance. RESULTS: All obstructed ureteral stents were successfully replaced with a new stent without endoscopy, percutaneous nephrostomy or any special devices. CONCLUSIONS: Our technique is simple, easy and highly successful for changing an obstructed ureteral stent.     

Long-term outcome of ileal conduit diversion

PURPOSE: Ileal conduit is considered a safe procedure and the gold standard to which newer forms of urinary diversion should be compared, although few long-term results are known. We analyzed a consecutive series of patients who lived a minimum of 5 years after ileal conduit diversion. MATERIALS AND METHODS: A total of 412 patients underwent ileal conduit diversion between 1971 and 1995 at our institution. We analyzed all conduit related complications occurring later than 3 months after surgery in 131 long-term survivors (survival 5 years or greater). RESULTS: Median followup was 98 months (range 60 to 354). Overall 192 conduit related complications developed in 87 of 131 (66%) patients. The most frequent complications were related to kidney function/morphology in 35 patients (27%), stoma in 32 (24%), bowel in 32 (24%), symptomatic urinary tract infection (including pyelonephritis) in 30 (23%), conduit/ureteral anastomosis in 18 (14%) and urolithiasis in 12 (9%). Within the first 5 years complications developed in 45% of patients. This percentage increased to 50%, 54% and 94% in those surviving 10, 15 and longer than 15 years, respectively. In this last group 50% had upper urinary tract changes and 38% had urolithiasis, for which the respective numbers after 5 years were 12% and 17%. CONCLUSIONS: This study demonstrates a high conduit related complication rate in long-term survivors and underlines the need for vigorous long-term followup. Only studies lasting more than 1 decade cover the entire morbidity spectrum.     

Jejunal conduits: technique and complications.

Thirty patients underwent jejunal urinary diversion: 27 bilateral cutaneous ureterojejunostomies, 2 cutaneous pyeloureterojejunostomies and 1 bilateral pyelocutaneous jejunostomy. In the majority of the cases this high diversion was indicated for malignant disease with preoperative and postoperative irradiation of the pelvis. Postoperative morbidity in these cases is not different from thatin cases of ileal conduit operation, except for a high incidence of reversible hypochloremic acidosis with hyponatremia, hyperkalemia and uremia. This electrolytic syndrome is the consequence of a continuous exchange of ions between the jejunal content and the extracellular fluid with resultant loss of sodium chloride and absorption of potassium and urea. An important link in the pathophysiology of the jejunal syndrome is the hypersecretion of renin-aldosterone, which aggravates the disturbance. Limited renal function (glomerular filtration rate less than 50 cc per minute), long loop and inadequate salt intake are among contributing factors. The syndrome is correctable by administration of salt. Some patients must be placed on salt supplement indefinitely. The jejunum is not recommended for urinary diversion in patients with limited renal function, those on low salt diet or those in whom a long intestinal loop would be required for diversion.     

Endovascular stent graft for management of ureteroarterial fistula: a case report

We report a case of ureteral-iliac artery fistula and its minimally invasive management with endovascular stent grafting. A 76-year-old male was admitted with massive gross hematuria from an ilial conduit. He underwent a radical cystectomy with ileal loop urinary diversion for bladder cancer 7 months ago and had undergone placement of a 7 Fr single-J ureteral catheter for repair of a partial disruption of the left ureteroileal anastomosis. Although the fistula was not confirmed radiographically, a left ureteral-common iliac artery fistula was highly suspected. The patient was treated by percutaneous placement of an autoexpandable covered stent graft across the left common iliac and left external iliac artery. After successful endovascular management of the ureteroarterial fistula, the patient's hematuria resolved and he recovered fully. During 10 months of follow up, he has been free of hemorrhagic episodes. Because open surgical repair may be difficult and associated with significant risk for complications, endovascular intervention may provide a safety treatment alternative.     

Hemiresective reconstruction of a redundant ileal conduit with severe bilateral ileal conduit-ureteral reflux

A 58-year-old man was referred to our hospital with high fever and anuria. Since undergoing a total pelvic exenteration due to bladder-invasive sigmoid colon cancer, urinary tract infections had frequently occurred. We treated with the construction of a bilateral percutaneous nephrostomy (PCN), and chemotherapy. Although we replaced the PCN with a single J ureteral catheter after an improvement of infection, urinary infection recurred because of an obstruction of the catheter. Urological examinations showed that an ileal conduit-ureteral reflux caused by kinking of the ileal loop was the reason why frequent pyelonephritis occurred. We decided to resect the proximal segment to improve conduit-ureteral reflux for the resistant pyelonephritis. After the surgery, the excretory urogram showed improvement and the urinary retention at the ileal conduit disappeared. Three years after the operation, renal function has been stable without episodes of pyelonephritis. Here we report a case of open repair surgery of an ileal conduit in a patient with severe urinary infection.     

Transitional cell carcinoma relapse in uretero-ileal conduit after radical cystectomy

Transitional cell carcinoma relapse in ileal conduit after radical cistectomy is a rare event, especially without upper urinary tract involvement. We describe a case of uretero-ileal transitional cell tumour five years after cistectomy for invasive urothelial tumour. Patient underwent endoscopic treatment with good results after 13 months of follow-up.     

Urinary undiversion using the existing ileal loop and distal right ureter

Urinary undiversion is an accepted technique in a highly selective patient population. We reconstructed the urinary tract in six female mongrel dogs. A 15 cm. segment of ileum was isolated, both ends were closed and bowel continuity re-established. The proximal two-thirds of each ureter were anastomosed to the proximal end of the ileal segment. The distal one-third right ureteral segment, in continuity with the bladder, was anastomosed end-to-side to the distal ileal segment. Information from the intravenous pyelograms, renal function tests, electrolytes and pathological studies showed normal upper tracts without dilatation or obstruction, preservation of renal function and normal electrolytes except for mild hyperchloremia in all 6 animals. There was chronic pyelonephritis in one animal and mild focal renal inflammation in two animals. The uretero-ileal anastomoses were patent and the ureters were not dilated. The interposed ileum functions well as a conduit and does not become a reservoir over time. We believe incorporating ileum into the urinary tract in this technique of undiversion is a safe and effective clinical alternative in selected patients.     

Calculus formation and ureteral obstruction after ileal conduit construction using autosuture stapling device

A case is presented of ureteral obstruction by a calculus-encrusted staple in a patient undergoing urinary diversion. This leads us to recommend that when an ileal conduit is constructed using the autosuture stapling device the staple suture line be excised from both ends of the isolated loop and the butt end of the ileal conduit be closed with absorbable material.     

Colocalicostomy. A solution to an obliterated renal pelvis

A thirty-nine-year-old paraplegic with an ileal conduit urinary diversion and long ureteral strictures bilaterally required urinary tract reconstruction to establish effective internal drainage. Reported techniques proved infeasible. Therefore, the right kidney with its small intrarenal pelvis was opened by anatrophic nephrotomy and anastomosed to a segment of transverse colon in two layers. The left kidney could not be anastomosed directly to the colon segment, so it was anastomosed end-to-side to an isolated jejunal segment. Colocalicostomy should be considered in the repair of an obliterated renal pelvis or an isolated, obstructed lower-pole calix.     

Renal function after urinary diversion. A study of continent caecal reservoir, ileal conduit and colonic conduit

Total and separate renal function, renal parenchymal thickness and dilatation of the upper urinary tract were studied in 40 patients preoperatively and 24 to 67 months after urinary diversion, using 51Cr-EDTA clearance test, scintillation camera renography and urography. In ten patients a continent caecal reservoir was used for diversion. In the other patients, an ileal or a colonic conduit (15 patients with each method) was used, one ureter being implanted with an anti-reflux method and the other with direct technique. Renal function following urinary diversion showed little or no deterioration in most patients. The functional outcome was not related to the method of diversion or, in the conduit groups, to the mode of ureteral implantation. Serum creatinine tests and urography were not adequate for determining loss of renal function. Radionuclide studies proved to be valuable for assessing renal function after urinary diversion.
