Spontaneous renal pelvis rupture (SRPR) is extremely uncommon and thought as a nontraumatic leakage of the urine from the renal pelvis. It is usually secondary to calculus causing obstruction. A clear differentiation between the forniceal rupture and upper ureter/ renal pelvis becomes very important as both course and treatment are different. Around seventy percent of ureteric stones are present in the distal ureter. Effective treatment of distal ureteric stone is by keeping the patient under observation and medication. These stones usually pass spontaneously under observation: however, some causes complication like urinary tract infection, hydronephrosis and abnormal renal function. Spontaneous perforation of the renal pelvis is a rare condition that leads diagnostic and therapeutic problems. We present a case report of male patient who is under conservative treatment presenting as spontaneous rupture of the renal pelvis with urinoma formation.
