Ureteral stent insertion is a common procedure in the urologic field. Although the migration of ureteral stent is uncommon, it can be serious complication. We report the migration of Thermo-Expandable Stent (Memokath) from upper ureter to renal pelvis, and which was managed by surgical removal after failed rigid and flexible ureteroscopic manipulation.

Pyelo-caliceal diverticulum refers to a cystic cavity containing urine the renal parenchyme, which is lined by transitional epithelium and communicates with the renal pelvis or a calyx through a narrow channel. Pyelo-caliceal diverticulum is a relatively uncommon entity and are usually quite small in size, averaging 0.5 cm to 5cm. Huge pyelo-caliceal diverticulum is presented with review of literatures.

Following results were obtained from the study on the distribution of segment arteries, the shape of collecting system and the correlation between collecting system and segment arteries using latex cast technique in normal kidneys of Korean. 1. In the cast of renal artery in normal kidney, renal artery divides into an anterior and posterior division. The anterior division gives rise to 3 segment arteries, i. e., upper, middle and lower segment arteries, while the posterior one continues and supplies only the posterior segment artery. 2. In the cast of collecting system, renal pelvis shows cone shape in general and it may be classified as fusiform and cylindrical forms. Major and minor calyces can be also classified as fusiform and cylindrical forms. 3. In the relationship between the cast of segment artery and that of collecting system, anterior branches divided from 3 segment arteries run in radiating from the anterior portion of pelvis, while posterior segment anterior portion of pelvis, while posterior segment artery crosses posterior portion of pelvis and supplies around superior major calyces. 4. In the view of above findings care should be given for the possibility of the injury to the posterior segment artery in the exposure of posterior portion of pelvis when pelvis, major and minor calyces reveal cylindrical forms on I.V.P.

In 200 patients with renal stone and upper and midureter stone, we have tried 241 sessions of percutaneous nephrolithotripsy. The success rate of nephrolithotripsy for different location and type was as follows. For renal pelvis stone 96.5%, staghorn stone lOO%, calyceal stone 84.4%, UPJ and upper ureter stone 76.8%, midureter stone 66.7%. We were successful in most of cases after preliminary report of earlier experience with 50 cases. And improvement of the result in removal of calyceal stone and upper ureter stone was especially conspicuous. In addition, we have complied experience with percutaneous removal of stone in patient with solitary kidney and of staghorn stone, and the result was satisfactory. Based on the accumulated experience, it was possible to remove almost all renal stones and most of upper and midureter stones by percutaneous approach although residual stones were present in large pelvis stone and staghorn stone. Thus in future, even when ESWL is widely utilized, endourologic management must be included in the algorithm of treatment of stone diseases to expect better success rate and less complications.

Ureteropelvic junction avulsion caused by blunt trauma is a rare condition which is often diagnosed after some delay. Herein, we report a case of traumatic ureteropelvic junction avulsion which has been treated successfully by end to end pyeloureterostomy.
