Spontaneous Renal Pelvis Rupture: Unexpected Complication of Urolithiasis Expected to Passage with Observation Therapy

Abstract

Seventy percent of ureteral stones are located at distal ureter. Effective and safe passage of distal ureter stones is mediated by observation or medical expulsive treatment. Most of stones located at distal ureter pass spontaneously under observation; however, some are complicated with urinary tract infection, hydronephrosis, and renal function disturbances. Spontaneous perforation of the upper ureter is a rare condition that poses diagnostic and therapeutic problems. This case is reported, because the patient developed an unexpected spontaneous renal pelvis rupture (SRPR), while she was under observation and expected to pass her right ureteral stone spontaneously through hydration and analgesic treatment.
