[Postoperative care of continent urinary reservoirs].

Continent urinary reservoirs like the Kock pouch, Indiana pouch or Mainz pouch are constructed from the detubularized intestine. These types of urinary diversion are good in regard to the quality of life, but meticulous postoperative care is required to avoid complications. Continent urinary reservoirs have common problems of mucous secretion and absorption of urinary constituents. Irrigation of the reservoir to remove the mucous debris is important to prevent stone formation and infections. The patient should be educated to perform the self catheterization properly and the danger of over-distention of the reservoir should be stressed. Periodic endoscopy of the reservoir is important to confirm whether a stone or a tumor is present or not. Measurement of electrolytes and vitamin B12 should be performed to correct abnormalities if present.

Direct percutaneous pouch cystostomy with endoscopic lithotripsy for calculus in a continent urinary reservoir.

Continent urinary reservoirs are an accepted mode of urinary diversion in appropriate patients. Such procedures are associated with long-term complications. A patient who underwent a continent urinary diversion (modified Indiana pouch) 4 years ago for a neurogenic bladder presented with a large irregular calculus in the pouch. Endoscopic attempts to remove the calculus through the stoma were unsuccessful and extracorporeal shock wave lithotripsy failed to fragment the pouch calculus. Finally, an endoscopic approach through a direct percutaneous pouch cystostomy, and use of ultrasonic and electrohydraulic probes resulted in successful fragmentation and removal of the calculus.

[The continent urinary reservoir].

Continent urinary reservoirs (CUR) have replaced ileum and colonic conducts as the best method for urinary diversion. The author present their experience with two patients in whom they fashioned a CUR in the Dr. Arnulfo Arias M. Metropolitan Complex using the ileocecal segment and part of the transverse colon (The Miami or Florida porch technique). They describe the clinical histories, surgical technique and the results obtained. They feel that the CUR has a large capacity, works at low pressure and is technically accessible. They consider it a good choice when urinary diversion is needed.

[Clinical studies on Kock continent urinary reservoir and Indiana continent urinary reservoir].

Recently, the continent urinary reservoir which provides the patient with a better quality of life has become popular. Many types of reservoirs have been reported, but the optimal procedure remains to be established. From July 1987 through November 1988, we performed Kock pouch construction on 11 patients (ages 39 to 76 years). Between July 1989 and March 1991, 9 patients (ages 44 to 66 years) underwent Indiana pouch operation. The first 4 patients underwent ileal patch type, and the subsequent 5 underwent Heineke-Mikulicz type procedure. A one-stage radical cystectomy and continent urinary reservoir construction was performed on 19 patients, and bilateral cutaneous ureterostomy was converted to Kock pouch in one patient. There were no perioperative deaths, but reoperation was required for urinary leakage from the reservoir on one patient in each group. As the late complications in the Kock pouch group, one patient required revisional operation of the continent valve mechanism, 2 patients experienced intermittent prolapse of the nipple valve of the efferent limb, and 2 had malfunction of the afferent nipple valve. In the Indiana pouch group unilateral hydronephrosis was noticed in one patient, and 4 had mild difficulty of catheterization. Although 3 patients in both groups had mild urinary leakage, all patients had good quality of life with capacity of reservoir over 500 ml and with good renal function. We changed the type of operative procedure from Kock pouch to Indiana pouch because of the high complication ratio in the former.(ABSTRACT TRUNCATED AT 250 WORDS)

A seromuscular stripping method to create a nipple valve without metal stapling for continent urinary reservoir.

Urinary continence with a Kock or Mainz pouch is achieved by a nipple valve of the invaginated ileum which is usually fixed with metal staples. However, metal staples can cause various complications as a foreign body. The seromuscular stripping method, a new technique to create a nipple valve, was applied to 17 patients with bladder cancer in the construction of a continent urinary reservoir by the ileocolonic pouch (Mainz pouch). Metal staples were not used. The results were satisfactory except for 2 patients who became incontinent because of prolapse of the nipple in one and insufficient valve function due to ischemic change of the nipple valve in the other. Histology of the nipple valve from an autopsy case showed a good double layer nipple valve that functioned well to preserve continence.

Urinary bacteriology of continent urinary reservoirs and calculus formation.

In order to investigate urinary bacteriology in relation to calculus formation in continent urinary reservoirs, a retrospective study was conducted of 19 patients with the Kock pouch and 23 patients with the Indiana pouch. Analysis of a total of 151 urine cultures showed that asymptomatic bacteria (any bacterial count) were present in 92% of urines from the Kock pouch and 74% from the Indiana pouch. The incidence of organisms and total bacterial counts were similar for both pouches. The most prevalent organisms were Escherichia coli, Pseudomonas sp., Klebsiella sp., Proteus sp., Enterobacter sp., and Enterococcus sp. Urinary calculi developed in 42% of the Kock pouch patients and 13% of the Indiana pouch patients. More than half of the patients had multiple stone recurrence. Infectious stones developed in 32% of the Kock pouch patients, usually on the foreign materials, and 9% of the Indiana pouch patients. In general, no clear relationship was established between urinary bacteriology and calculus formation although Proteus sp. or Providencia sp. was determined to be the causative organism in some infectious stones. Furthermore, metabolic stones developed in 32% of the Kock pouch patients and 9% of the Indiana pouch patients. Because calcium phosphate was a constituent of 80% of the metabolic stones, the presence of urinary factors promoting calculus formation was suspected.

Continence and urodynamic parameters of continent urinary reservoirs: comparison of gastric, ileal, ileocolic, right colon, and sigmoid segments.

OBJECTIVES: To compare the urodynamic parameters and continence rates among five different continent urinary reservoirs. METHODS: Continent urinary reservoirs were constructed in 40 patients with an average age of 60 years (range 23 to 81). Twenty-three had orthotopic neobladders ("neobladders"), and in 17 the reservoirs exited by way of an abdominal wall stoma as "stomal urinary reservoirs." In the neobladders, the detubularized segment was ileum (Hautmann) in 5, ileocecal (Mainz) in 8, sigmoid in 4, and gastric in 6. In the stomal urinary reservoirs, the segment was ileocecal in 11 (Mainz) and right colon in 6 (Indiana). Urodynamic studies were performed at a mean of 9.1 months. RESULTS: Stomal urinary reservoirs had the best continence rates (Indiana pouch 100%, Mainz pouch 91%). Neobladder continence rates were as follows: Hautmann, 80%; Mainz, 75%; sigmoid, 50%; and gastric, 33%. Day and night incontinence rates were nearly identical. Compared with the other pouches, gastric and sigmoid reconstructions had the smallest capacity, were the least compliant, and were the most contractile. CONCLUSIONS: Stomal urinary reservoirs using ileocecal valve and right colon, with or without an overlying patch of ileum, provide similar excellent results. Continence approached 100% in compliant patients without the need for revision. Patients with neobladders were less continent, although those with ileal or ileocecal configurations still had very good continence rates. Neobladders of sigmoid or stomach can be used when necessary, but with greater incontinence rates. This poorer continence can be explained by the decreased capacity, decreased compliance, and a tendency toward high pressure spikes despite detubularization.

Ureteric obstruction due to kinking of the reservoir inlet in a continent urinary reservoir.

We report a case of symptomatic intermittent upper tract obstruction in a continent urinary reservoir. The ureters were of great intraperitoneal length and were positioned in front of the mesenterium, resulting in a mobile reservoir. Only the retroperitoneal part of the ureters was dilated due to kinking in the peritoneal passage. After the ureters were shortened and reanastomosed retroperitoneally, the repeated episodes of abdominal pain and discomfort disappeared..

Evolution of the Indiana continent urinary reservoir.

The Indiana continent urinary diversion evolved from the Gilchrist procedure. Full detubularization of the reservoir segment, tapering of the efferent limb with staples, plication of the ileocecal valve, and tunneled tenial implants have resulted in a reliable and reproducible continent cutaneous urinary reservoir. In this report the first 69 patients treated with these techniques are reviewed after a minimum 2-year followup. Overall day and night continence rates were 97% by 1 year after surgery. More than 80% of all patients are able to sleep a normal nighttime interval without catheterizing or leaking. Early plus late reoperation rates for problems related to the pouch were 17%. This rate compares favorably to other series of continent cutaneous reservoirs and even to series of ileal conduits.

Multiple large calculi in a continent urinary reservoir: a case report.

Continent urinary reservoirs have increasingly become popular during the last decade but they are associated with long-term complications. We report a case of huge multiple stones in an ileocecal reservoir, which formed as a result of noncompliance with intermittent self-catheterization. An open method was required for removal of the stones to prevent recurrent urosepsis.

Nonsurgical management strategies for the functional complications of ileocolonic continent urinary reservoirs.

Urinary diversion with creation of a continent ileocolonic reservoir was performed in 25 patients with gynecological malignancies at our institution between September 1989 and September 1994. A retrospective review was conducted and cases were analyzed for functional complications associated with reservoir formation. Functional reservoir complications were defined as (1) difficulty with catheterization, (2) reservoir fistulae, (3) reservoir stones, and (4) ureteral stenosis. Management strategies and outcomes for these complications were determined. All patients had received prior pelvic radiation therapy. There was no surgical mortality. Median follow-up was 21 months, and 16 patients (64%) are currently alive. Fourteen of the patients (56%) had one or more complications attributable to a functional aspect of the continent reservoir. Two patients had difficulty with catheterization (8%), two patients had reservoir leak (8%), and one patient had reservoir stones (4%). Nonsurgical management strategies were used in these cases including balloon dilation of the ileocecal valve, stomal dilation, ureteral stenting, percutaneous nephrostomy, and endoscopic lithotripsy. All cases of catheterization problems, reservoir fistulae, and reservoir stones were resolved with nonoperative techniques. Thirteen of 50 ureters (26%) had some degree of stenosis. Percutaneous balloon dilation was utilized in nine cases of ureteral stenosis. Relief of stenosis was complete in five, partial in two, and not achieved in two of the cases. No patients required a reoperation for a reservoir complication. In conclusion, continent ileocolonic urinary diversion can be performed in patients previously treated with radiotherapy; however, functional reservoir problems may occur. Interventional radiology strategies are useful in managing many of these problems and reexploration can be successfully avoided.

[Indiana continent urinary reservoir: report of 15 cases].

Over the last several years, internal reservoir type urinary diversions have become popular. We have already performed Kock continent ileal reservoir for urinary diversion in more than 80 patients. The experience with the Kock pouch prompted us to try a new form of continent urinary reservoir originally reported by Indiana University group. The Indiana pouch is a composite structure using ileum and cecum. The antireflux mechanism is provided with tunneled ureteral implantation along the tenia of the cecum. Plication of the terminal ileal segment along with the ileocecal valve maintains urinary continence. The tubular configuration of the cecum is completely disrupted with either an ileal patch or Heineke-Mikulicz re-configuration to construct a low pressure reservoir. Between October, 1987 and September, 1988, we performed Indiana continent urinary diversion in 15 cases: 13 males and 2 females, from 47 to 73 years old (mean age 61.3 years), 14 bladder cancer patients and 1 bladder sarcoma patient. The initial 8 patients underwent Heineke-Mikulicz type operation and the subsequent 7 patients ileal patch-type operation. Median followup has been 7 months. There were no major early complications but one postoperative death with blood transfusion related graft versus host disease (GVHD). The late complication occurred in 2 patients: 1 stenosis of the pouch due to insufficient detubularization of the cecum and 1 pyelonephritis required no admission. Serum electrolytes and vitamin B12 remained normal in all patients. Patients perform self-catheterization every 3-5 hours during the day and 0-2 times at night for volumes ranging up to 800 ml. With regard to volume capacity and pressure characteristics, the ileal patch type reservoir seemed to be superior to the Heineke-Mikulicz type pouch as a receptacle for urine. Over-all, 12 of 14 patients (86 per cent) have acceptable continence. The remaining 2 patients have significant daytime leakage requiring pads or a cutaneous bag. Followup examination with excretory urography showed no upper tract obstruction and X-rays of the pouch showed no reflux. Indiana pouch is a relatively simple continent urinary reservoir, since the steps of this technique already are familiar to urologists. It may be an alternative form of continent urinary diversion.

Acute, late presentation of colo-continent urinary reservoir fistula.

Complications associated with continent urinary reservoirs are well recognised. Fistulae between the pouch and colon are rare but are documented. This uncommon complication is reported in the early post-operative period in patients who have previously received pelvic radiotherapy. Colonic fistulae are normally secondary to malignancy or diverticular disease. We present the first literature report of a late, acutely presenting colo-pouch fistula secondary to neither malignancy nor diverticular disease. We highlight the need for medical staff to be aware that not all stomas are incontinent and the possible dangers to be aware of when an acutely unwell, debilitated patient is unable to convey this fact.

[Detubularized right-hemicolonic continent urinary reservoir with plicated terminal ileum].

A continent urinary reservoir which consists of 1) detubularized caecum, ascending colon and the right half of transverse colon. 2) anastomosis of ureter and ascending colon with antireflex technique, and 3) plicated terminal ileal segment for continence and catheter insertion was created in 12 patients after radical cystectomy for urothelioma. Our method to create a continent urinary reservoir is simple and technically easy. It can, therefore, provide patients' satisfaction with low incidence of complication. However, such continent urinary reservoir diversion should be performed only for carefully selected patients, taking into consideration the physical status and the character and social status of the patient. This is because some patients who have had such surgery may change their mind to keep a balloon catheter to avoid the intermittent self-catheterization every 3 to 4 hours after surgery.

Conversion of an incontinent urinary conduit to a continent urinary reservoir (Miami Pouch).

OBJECTIVE: External urinary or gastrointestinal appliances can impair a patient's quality of life. We report on the feasibility of converting an incontinent colonic urinary diversion to a continent urinary reservoir (Miami Pouch). CASE: We describe the case of a 66-year-old white female with a history of stage Ib(2) cervical cancer treated by radical abdominal hysterectomy and adjuvant radiation therapy. The patient developed severe radiation cystitis with a neurogenic bladder and bilateral ureteral obstruction. After failing conservative management, a urinary diversion with a transverse colon conduit was performed. The patient remained without evidence of disease for 2 years and led an active lifestyle with regular tennis games. After 7 months of an external appliance for the urinary conduit, the patient presented to the University of Miami for conversion to a continent urinary mechanism which would not require an appliance. We performed an exploratory laparotomy, conversion of a transverse colon conduit to a continent ileo-colonic urinary reservoir (Miami Pouch). There were no postoperative complications. The patient remains disease-free and performs self-catheterization with no need for an external appliance. The patient has been able to resume an active life including sports. CONCLUSIONS: Successful conversion of an incontinent urinary conduit to a continent urinary reservoir is possible in a select case resulting in a perceived improvement of quality of life.

Urinary immunoglobulins in patients with continent urinary reservoirs and ileal conduits.

BACKGROUND: Although bowel segments are commonly used for reconstructing the urinary tract, a high incidence of bacteriuria is observed in patients with urinary intestinal diversion. The normal gastrointestinal tract possesses a potent mucosal immune system characterized by secretory immunoglobulin A (sIgA) as the major humoral defense factor. However, the significance of urinary IgA secretion as the mucosal defense mechanism in patients with urinary intestinal diversion has remained obscure. In this study, urinary levels of sIgA as well as serum-type IgA were measured in patients with continent urinary reservoirs (Kock and Indiana pouches) and ileal conduits. METHODS: Twenty-four-hour urine samples were collected in a total of 80 patients with urinary intestinal diversion (22 Kock pouch patients, 21 Indiana pouch patients and 37 ileal conduit patients). The amount of sIgA and serum-type IgA were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: Urinary IgA levels showed great inter- and intra patient variability in all three groups. Indiana reservoir urine contained significantly greater amounts of sIgA (mean 32.0 mg/24 hrs) than Kock reservoir urine (11.9 mg) and conduit urine (4.9 mg), whereas Kock reservoir urine contained significantly more sIgA than conduit urine. However, the corresponding difference was not observed in regard to serum-type IgA. In none of the three modes of urinary diversion did 24-hour sIgA excretion show any correlation with the length of time after surgery. CONCLUSIONS: Since the amounts of sIgA in these patients were much greater than reported in urinary tract infection as well as in normal subjects, the major portion of urinary sIgA seemed to be secreted by the intestinal segments. Long-term sIgA secretion in urinary intestinal diversion, especially continent urinary reservoirs, may be an important host defense system.

Utilization of ileal conduit in construction of continent urinary reservoir.

Two patients with ileal conduits underwent planned urinary undiversion; in both patients, the previously constructed ileal conduit was utilized to augment the continent urinary reservoir. Both patients are totally continent with stable upper urinary tracts; neither individual suffers from diarrhea or intestinal absorption abnormalities. This variation in the construction of the continent urinary reservoir allows for the usage of less terminal ileum, and as a result, the risk of intractable diarrhea as well as folate and vitamin B12 malabsorption should be diminished. The criteria that must be met to utilize the ileal conduit in the construction of the continent urinary reservoir include: (1) adequate remaining conduit length after mobilization, and (2) a normal-appearing conduit with sufficient mesenteric length after mobilization.

[Quality of life of the patients with continent urinary reservoir].

To improve the quality of life (QOL) of patients requiring urinary diversion, various surgical techniques including those employing a continent urinary reservoir (CUR), such as Kock pouch or Indiana pouch, and those using the conventional ileal conduit have been advocated. In this study we asked patients who had undergone a CUR operation to complete a questionnaire, consisting of 106 questions relating to the QOL during the disease-free period. A total of 81 questionnaires were sent out, and 60 (74.1%) CUR patients responded. The average age was 61 and the male to female ratio was 49 to 11. The time elapsed from the operation was 42 months. Twenty-nine questions addressed the patients physical condition and on the whole it was kept in good quality. Because they were unwilling to show their stoma, they were reluctant to bathe together with family members. However, 59% of them went to a public bathhouse (common in Japan). Other physical abilities related to exercise were not significantly hampered by this operation. Eighty per-cent of them were not bothered by having a stoma. Twenty four questions were related to social life. The operation had a bad influence in 20-30% of them concerning their interaction with friends and hobbies. Twenty two percent of the patients who had a job prior to the operation stopped working. Only a few patients abandoned travelling. Concerning their sex life (7 questions), males suffered impotence at a very high rate, but only 26% of the patients lost interest in sex. Symptoms related to the operation (41 questions) were mild. Overall, 94% of the patients would choose the same operation again if it were required.(ABSTRACT TRUNCATED AT 250 WORDS)
