Imaging of the Kock continent ileal urinary reservoir.
The Kock continent ileal urinary reservoir (Kock pouch) is a new urinary bypass system that can overcome some of the principal complications associated with other forms of urinary diversion. It is important to understand the anatomy and radiology of this new technique since radiologists play an important role in evaluating the function of the Kock pouch as well as assessing its complications. The authors review the clinical and radiographic findings in 193 patients who had undergone Kock pouch urinary diversion. Patients are evaluated radiographically in the immediate postoperative period and at regular postoperative intervals for as long as 3 years. Routine evaluation consists of Kock pouch cystography followed by intravenous urography. When indicated, computed tomography, ultrasound, and interventional radiologic procedures are used. The normal anatomy as well as the radiographic appearance of the Kock pouch is presented. In addition, the radiographic appearance of pouch complications and their frequency are reviewed.
