The present study was performed to compare the results of radiologic examination and endoscopy in 156 patients with continent ileostomy reservoirs. Data from clinical follow-up and findings at revisional surgery were used for confirmation of diagnosis. One hundred and one patients had the clinical diagnosis nonspecific inflammation, 48 had symptoms of valve dysfunction, and 7 were studied because of suspected valve-shunting fistulas. For moderate and severe inflammation the findings on radiographs and at endoscopy were in accordance, whereas slight inflammation was more frequently reported by radiology than endoscopy. Radiology overdiagnosed slight inflammation. One disadvantage of endoscopy in patients with inflammation was that the afferent ileal segment could be reached in only 56%. By radiology 41 of 44 defective valves were identified (93%), whereas endoscopy disclosed only 24 defective valves (55%). The combined efforts of radiologic examination and endoscopy only managed to diagnose three of the seven patients with valve-shunting fistulas (two by radiologic and one by endoscopic examination). In conclusion, the retrograde double-contrast examination is a valuable complement in the assessment of patients with continent ileostomies and appears to be superior to endoscopy in the diagnosis of valve dysfunction and in depicting the afferent ileal segment.

Drainage of the Upper Urinary Tract as Recorded with Renography in Patients with a Continent Urostomy (Kock Pouch)

Scandinavian Journal of Urology and Nephrology (1987)

The drainage from the upper urinary tract was studied by the use of renography in thirteen patients with well functioning continent ileal reservoirs for urinary diversion (Kock-pouch). Renography was performed with empty reservoir and with submaximal or maximal filling of the reservoir. The reservoir pressure was continuously recorded when renography was performed with a full reservoir. When the reservoir was empty renography showed normal drainage in all patients. When the reservoir was full the renography was normal in eight patients, these having a mean reservoir volume of 715 ml but showed a delay in five patients, these having a mean reservoir volume of 930 ml. When the renography was repeated in the latter group of patients with submaximal filling (mean reservoir volume 544 ml) there was no delay of the drainage phases on the renograms. In these five patients the considerable “over-filling” of the reservoir had resulted in volumes greatly exceeding the previously recorded maximal reservoir capacity and also in pressures exceeding considerably those usually recorded in ileal reservoirs. These results show that the pressure in the bladder substitute is of great significance for the drainage from the upper urinary tract and that the low pressure ileal reservoir under ordinary circumstances does not obstruct the flow from the upper urinary tract.
