- To study Kock reservoir maturation in children and adolescents and its effects on the kidneys and upper urinary tract.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.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.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.

- OBJECTIVE: The aim of this study was to describe the clinical characteristics of early onset prostate cancer, with special reference to family history as a possible prognostic factor.MATERIAL AND METHODS: We identified all cases of prostate cancer diagnosed before the age of 51 in the Southern health care region in Sweden between 1958 and 1994. Clinical data were collected retrospectively from medical records. Data about family history of prostate cancer were also collected from the parish authorities and the Regional Cancer Registry.RESULTS: In all, 89 cases were included. The median time of follow-up was 17 years. During the time of follow-up, 65 patients died, 57 of whom died from prostate cancer. At diagnosis, 34% of the patients had localized, 22% had locally advanced, and 40% had metastatic tumours. The tumours were well differentiated in 30% of the cases, moderately differentiated in 38%, and poorly differentiated in 28%. Information on tumour grade and stage was missing in 3 cases. The cause-specific survival was 48% at 5 years and 29% at 10 years. The 18 patients with a family history of prostate cancer had a somewhat better prognosis than the patients with a negative family history, though the difference did not reach statistical significance (p = 0.08).CONCLUSIONS: Early onset prostate cancer is a serious disease with high mortality. The proportions of patients with poorly differentiated and metastatic tumours appeared to be larger than for cases diagnosed later in life, but this could be explained by selection bias since younger men may have a lower probability of having asymptomatic localized tumours diagnosed. Family history of prostate cancer was not significantly associated with prognosis.
