Huge Perirenal Urinomas in a Woman during the Postpartum Period / 대한비뇨기과학회지

Urinary tract dilation is one of the most common side effects during pregnancy. This is primarily a physiologic phenomenon that is typically more prominent on the right side, and it is caused by hormonal changes and mechanical obstruction. Occasionally, urinary tract dilation leads to more serious urinary tract problems such as infection, obstructive renal failure and urinomas. Urinomas are also known as pararenal pseudocysts, and they generally occur as a result of urinary system disruption, but they only rarely occur with pregnancy. We report here on an unusual case of extremely large bilateral perirenal urinomas that were detected during the postpartum period. This was successfully resolved by percutaneous drainage and ureteral stents.

Retroperitoneal Lymphangioma Following Pyeloplasty in Child / 대한비뇨기과학회지

A lymphangioma is a rare benign congenital tumor of the lymphatic system, resulting from the failure of lymphatic drainage into the venous system, which is due to atresia or the insufficiency of an efferent lymphatic channel. A lymphangioma usually occurs in the neck or axillary region. A retroperitoneal lymphangioma is very rare. Herein, a case of a retroperitoneal lymphangioma incidentally found four months after performing pyeloplasty on a child, is reported.

Comparative Analysis of Extracorporeal Shock Wave Lithotripsy: Does Sonolith Praktis Have Any Advantage over EDAP LT-02? / 대한비뇨기과학회지

PURPOSE: We wanted to compare the effectiveness, safety and cost of performing extracorporeal shock wave lithotripsy (ESWL), and so we reviewed the outcomes of patients with urinary calculi that were treated with the EDAP LT-02 lithotriptor (LT-02) and the Sonolith Praktis lithotriptor (Sonolith). MATERIALS AND METHODS: 2,141 cases treated with the LT-02 and 198 cases treated with the Sonolith were retrospectively reviewed. The success rate and the number of sessions, according to the size and location of the stones, were statistically analyzed. Auxiliary measures, other treatment modalities, complications and the running cost of the entire treatment were also reviewed. RESULTS: The success rate (stone free or residual fragments <4mm in diameter) between the LT-02 and Sonolith, according to the stone size and location, showed no significant difference. The overall success rate was 96.4% and 96.5%, respectively. The mean number of treatment sessions was 3.0 for the LT-02 and 2.0 for the Sonolith. The efficiency quotient was 45.5 for the LT-02, which was lower than 54.0 for the Sonolith. No significant difference was observed in the occurrence rate of complications and the auxiliary measure rate between the LT-02 and the Sonolith. The cost of overall treatment was 1.33x10(6) won for LT-02 and 1.12x10(6) won for Sonolith. CONCLUSIONS: The results suggest that the efficacy of the Sonolith is approximately equal that of the LT-02. However, the Sonolith has superiority in reducing the number of treatment sessions and lowering the overall treatment cost.
