Bilateral triple renal pelvis: a case report.

INTRODUCTION: Triple renal pelvis is an extremely rare variation of the renal collecting system. To the authors' knowledge, bilateral triple renal pelvis has not yet been described in the literature. CASE REPORT: A 55-year-old man was hospitalized due to papillary bladder cancer, detected on ultrasonography. As incidental finding, intravenous urography revealed bilateral triple renal pelvis. Six weeks after transurethral resection of the bladder tumor (TURB) the patient was admitted again, for the second TURB. Computed to mography-urography confirmed the presence of bilateral triple renal pelvis. CONCLUSION: The unique case of bilateral triple renal pelvis was presented as an extremely rare variation of the renal collecting system.

The dissolution of multiple renal uric acid stones via percutaneous nephrostomy in the patient with a solitary kidney.

INTRODUCTION: The dissolution of urinary stones could be performed in the patients with urinary obstruction caused by phosphate, or uric acid stones, through the percutaneous nephrostomy (PCN). CASE REPORT: A 27-year-old woman with complete obstruction of the solitary left kidney due to uric acid stones is presented. The woman was admitted in emergency unit due to anuria. Five days after PCN, irrigation with 1.6% sodium bicarbonate solution was initiated. Due to complete ureteral obstruction, the "Y" extension with the valve was connected to PCN and to the urinary bag, which enabled the patient to perform intermittent self-irrigation. After 12 days of irrigation, all the stones dissolute and ceased. CONCLUSION: In the era of ESWL, PCNL and ureterorenoscopy, PCN-dissolution of urinary stones is rare procedure. However, this minimally invasive procedure could be successfully performed in selected cases.
