RESUMEN
OBJECTIVE: To assess quality of life after continent ileal reservoir diversion in children and adolescents. MATERIAL AND METHODS: Nine boys and 9 girls (10.8-18 years old at surgery) were operated with a Kock reservoir and followed for 5-12 years. They participated in an interview using a questionnaire based on the Swedish self-esteem inventory, "I think I am". The questionnaire consisted of 76 questions that covered medical, physical, psychological, social, body image and sexual aspects. RESULTS: Six of 18 patients had some difficulties on catheterization. Five complained of pain or bleeding during evacuation. Two patients had slight urinary leakage between evacuations and 6 had mucus secretion. Ten patients had diarrhea with different frequencies. Physical activities were not hampered by the operation in any patient. Instead, activities such as full day outside home, friend at home overnight, using all types of clothes, and participation in camps were increased in 8, 6, 5 and 5 patients, respectively. All patients but 2 had an excellent relation with friends and family members. More than half of patients had excellent positive self-esteem and body image and the rest had very good self-esteem. However, some patients were concerned about how they looked and felt that life was unfair to them. CONCLUSIONS: The patients were satisfied with their operation. They were physically active and declared a positive perspective regarding self-esteem and body image. The medical problems related to the operation did not have any negative influence on the self-esteem or body image. The choice of the operation can only be determined on the basis of an attentive dialogue between surgeon, child and parents.

OBJECTIVE: To study Kock reservoir maturation in children and adolescents and its effects on the kidneys and upper urinary tract. METHODS: Ten boys and 10 girls, aged 10.8-18 years, had Kock reservoir surgery for congenital urinary incontinence. They were followed for 3-10 years, divided into 3 different periods, and assessed with urography and enterocystography, the findings of which were correlated to renal function as measured by (51)Cr EDTA clearance, reservoir endoscopy and patient's history. RESULTS: The reservoir was located in the pelvis and remained in this position throughout the whole follow-up in 75% of patients and in the lower or midabdomen in 25%. Angled efferent nipple seen on enterocystoscopy or enterocystography coincided with nipple dysfunction, reservoir malposition or infrequent reservoir emptying. Upper urinary tract dilatation was detected in 84% of patients 3 months after surgery, 25% at 1 year and 30% at 2-10 years. The dilatation was improved in 56% of patients and unchanged in 25% after 1 year. The situation continued to improve at late follow-up. New focal renal scars were radiologically detected in 1 of 19 at early and in another 1 of 17 patients at late follow-up. Progression of old scars was detected in 1 of 19 at early and in 4 of 17 at late follow-up. Eight of 19 cases had deterioration of renal function with a change in the split renal function. Of these 8 patients, 7 reported infrequent reservoir evacuation. CONCLUSIONS: Kock reservoir is a useful form of urinary diversion in children and adolescents with congenital urinary incontinence. Radiological examinations are good methods of follow-up of the maturation of the pouch and its effects on the urinary tract and for detection of complications. Urinary tract dilatation is a frequent finding early after surgery but it subsides in most cases 3-12 months after surgery. Long-term efferent nipple dysfunction may be the result of angulation, reservoir stones, malposition and/or overdistension. Permanent renal damage may be due to pyelonephritis, stones, infrequent reservoir emptying or urinary obstruction. A strict regime of reservoir evacuation to avoid overdistension and nipple dysfunction and to decrease the possibility of renal function deterioration is strongly advisable in these patients. It is imperative that their own management of the reservoir is continuously supervised.

The aim of this study was to evaluate Kock reservoir function in children and adolescents operated for congenital urinary incontinence and to determine the complication rate. Reservoir function was investigated in 13 children (age range 10.8-16 years) and 7 adolescents (age range 16-18 years) through enterocystometry, enterocystoscopy and patient history. Patients were followed up for 3-10 years. The follow-up was reported as early (3 months-2 years) and late (2-10 years) postoperative periods. At early follow-up reservoir capacity was high in four patients and normal in the remaining patients. A low reservoir pressure was accompanied by high capacity and compliance. On enterocystometry first sensation for emptying was experienced in 82% of patients at early follow-up and 92% at late follow-up. Reservoir contractions were recorded in 60% of patients at early follow-up and 65% at late follow-up. The contractions were recorded at an average reservoir capacity of 270 ml at early follow-up and 340 ml at late follow-up. The complication rate was high in the child group compared with that in adolescents. Of 13 patients with at least one reservoir complication 10 were from the child group. Nipple dysfunction (angled nipple, prolapsed or stenosed stoma) occurred in 35% of patients, stones in 40% and bleeding during catheterization in 15%. Revision was performed in 38% of the child group and 15% of the adolescents. Reservoir perforation was observed in two patients at 6 and 9 years postoperatively. At late follow-up continence was excellent in 17 of 19 patients and good in 2. We conclude that the Kock reservoir is a good modality for urinary diversion, but the complication incidence is high in the child group (<16 years). Stability of the reservoir in terms of volume and low internal pressures was achieved one year after operation, except in the patients with infrequent reservoir emptying. A time-related increase in the reservoir sensitivity and contractility was reported on enterocystometry. Nipple dysfunction is common during the first two years after surgery, particularly in the child group. Stones may form 3-4 years after surgery. Satisfactory continence was achieved in all patients, although a revisional operation was necessary in some patients in order to obtain permanent continence.

OBJECTIVE: To assess the early and late metabolic effects of urinary diversion in children and adolescents with a Kock urinary reservoir. PATIENTS AND METHODS: Thirteen children (aged 10.8- 16 years) and seven adolescents (aged 16-18 years; 10 girls and 10 boys), underwent surgery for congenital urinary incontinence. They were followed for 3-10 years (mean 6.5), divided into an early (3 months to 2 years) and a late (2-10 years) period, and assessed for renal function and any metabolic effects. RESULTS: At the early and late follow-up, one of 19 and three of 16 patients, respectively, had metabolic acidosis. Hyperchloraemia was present in four of 20 patients at the early and in eight of 18 at the late follow-up. Serum creatinine was increased in four of 20 patients at the early and eight of 18 at the late follow-up. In patients with infrequent reservoir emptying (=4 times/day), the serum creatinine level was increased in seven of 13 at the early and eight of 10 at the late follow-up (P<0.05). The glomerular filtration rate was below normal in four of 20 patients preoperatively, in six of 19 at the early and in eight of 18 at the late follow-up. CONCLUSIONS: The continent ileal reservoir in children and adolescents produces similar changes to those previously reported in adults. However, almost all patients with metabolic disorders were younger than 16 years at operation. The pre-existing impairment of renal function, together with associated congenital anomalies, mental and/or physical disorders, young age, recurrent urinary tract infections and infrequent reservoir emptying, leads to deterioration in renal function after the Kock operation. Even with this risk, the Kock pouch remains a viable alternative to other forms of continent urinary diversion, because it has a wide calibre stoma, allowing large-bore catheters, and is therefore especially suitable for individuals with weak hand function, e.g. quadriplegic or meningomyelocele patients. However, as shown by these results, the child with a Kock pouch requires continuous medical attention.
