Abstract
- Pyelocaliceal diverticula are eventrations of the upper collecting system, lying within the renal parenchyma and communicating with the main collecting system via a narrow channel. They may be detected in as many as 0.5% of excretory urograms but are usually small(<1cm in diameter) and asymptomatic. Urinary stasis may predispose patient to infection or stone formation. Rarely, transitional cell carcinoma originates within the diverticulum. Symptomatic, complicated diverticula should be treated by 5 different therapeutic alternatives which is open surgery, a percutaneous approach, shock wave lithotripsy ureterorenoscopy and retroperitoneoscopy. We report a incidentally found calculi-containing type I pyelocalyceal diverticulum patient who initially presented with epigastric pain.
