Diagnosis is made by contrast-enhanced computed tomography or retrograde pyelography, and management may be active or conservative. We present the case of a 79-year-old woman who developed SRPR of the left kidney on the fifth postoperative day of a right laparoscopic nephroureterectomy with endoscopic bladder cuff resection. Active management was decided and a ureteral catheter was placed. Symptoms improved and the patient did not develop any complications during follow-up. This case report explores SRPR, a condition with traumatic and non-traumatic causes, including urethral calculi and congenital abnormalities. SRPR is the result of a sudden increase in intraluminal pressure, often exceeding 20–75 mmHg, causing tissue tearing at the weakest urinary tract point, the fornix. In this instance, the patient experienced contralateral renal pelvic rupture following nephroureterectomy with no apparent cause for elevated intrarenal pressure. We propose that bladder irritation after ureteral cuff resection induced spasms, triggering the rupture. Diagnostic challenges arise as initial symptoms mimic renal colic, later manifesting as a urinoma. Imaging techniques, such as ultrasonography and contrast-enhanced CT, aid in the diagnosis. Treatment options encompass ureteral stenting and conservative management, with the choice depending on the patient’s condition. This case underscores the significance of early recognition and management of SRPR, especially following nephroureterectomy. In conclusion, SRPR is an entity that requires immediate management. It is important to evaluate if there are any features that require active treatment.

Diagnosis and treatment of spontaneous rupture of renal pelvis caused by pelviureteric junction obstruction in infants

Objective To analyze the clinical features of spontaneous rupture of the renal pelvis (SRRP) in infants caused by UPJO. Methods A retrospective analysis of 7 cases of SRRP in infants caused by UPJO in our hospital from October 2013 to October 2018 was performed. All the patients included 5 males and 2 females. The average age was(12.0±6.1) months(ranging 2 days-25 months). 3 cases suffered renal rupture in left side and 4 cases suffered renal rupture in right side. 2 cases had grade Ⅲ hydronephrosis and 5 cases had grade Ⅳ hydronephrosis. Other symptoms included fever in 4 cases, digestive symptoms in 3 cases, oliguria in 2. 7 cases were revealed RBC(+ + + )with urinary occult blood positive in urine test. 6 cases were found the white blood cells in urine was more than 8/μl. 3 cases had the elevated blood C-reactive protein.3 cases suffered with renal function insufficiency, which the creatinine was more than 110 μmol/L. The 2 cases of urinary extravasation was found in the posterior abdominal cavity and 2 in posterior abdominal cavity and abdominal cavity by CT enhanced scan. 4 cases performed open pyeloplasty, nephrostomy and perirenal drainage.2 cases performed pyeloplasty, nephrostomy, abdominal and perirenal drainage. 1 case performed perirenal drainage and retrograde indwelling Double-J stents. Results All operation performed successfully. The median operation time was 84 min (ranging 45-90 min). The estimate blood loss was 15 ml (ranging 10-35 ml)without any transfusion. The median time of postoperative perirenal drainage tube was 3 d (ranging 2-5 d), The median time of the abdominal drainage tube was 5 d (ranging 3-7 d), the median time of nephrostomy was 12 d (ranging 10-14 d). The median hospital stay was 14 d (ranging 10-21 d). The median follow-up was 18 months (ranging 3-36 months). One performed the second stage pyeloplasty after double-J stents removed, and the renal function gradually recovered. Conclusions The SRRP in infants caused by UPJO is rare and easily misdiagnosed. The degree of hydronephrosis and inflammation may be important factors affecting the spontaneous rupture of pediatric renal pelvis. When it occurs, it requires active intervention by the operation, while treating the stenosis of the UPJ and draining the extravasation of urine.

Spontaneous Rupture of Renal Pelvis: A Rare Complication of Obstructive Ureteral Stone

Spontaneous Rupture of Renal Pelvis: A Rare Complication of Obstructive Ureteral Stone

Spontaneous rupture of renal pelvis as a rare complication of ureteral lithiasis.

Spontaneous rupture of renal pelvis with urine extravasation is a rare condition and usually associated with obstructing ureteric calculus. It poses diagnostic and therapeutic dilemmas, while a stepwise approach for the confirmation of diagnosis, treatment and follow up is needed. We present a case of a 75-year old male patient who had a renal pelvis rupture with perirenal extravasation of urine due to a 4 mm stone located at the right ureterovesical junction. Diagnosis was confirmed by computed tomography, while the patient was treated successfully with the placement of a percutaneous nephrostomy. A week later a CT- nephrostomography showed the healing of renal pelvis with no extravasation and no evidence of the obstructing stone.

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

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.

Spontaneous Renal Pelvis Rupture Due To Ovarian Carcinoma: Case Report

Peripelvic extravasation related to spontaneous rupture of the renal pelvis is a rare occurrence, but is commonly associated with obstructing calculus. Spontaneous renal pelvis rupture and urinoma due to a tumor is very rare. In this case report, clinical presentation and radiological imaging findings of a case with development of renal pelvis rupture and peripelvic extravasation due to ovarian carcinoma is discussed.

The importance of gray scale and color Doppler ultrasonography in the diagnosis of spontaneous renal pelvis rupture: case report

Peripelvic extravasation associated with spontaneous rupture of renal pelvis is a rare occurrence, caused mostly by the obstruction due to calculus. However, the presence of renal anomalies increases the risk of rupture. Urinary extravasation leads to flank pain and may cause acute abdominal symptoms. Especially, the displacement of viscera by extravasated urine and the presence of gastrointestinal symptoms arising through intestinal reflex stimulation renders diagnosis more difficult. Ultrasonography, intravenous urography and computed tomography are the most efficient diagnostic tools in the diagnosis of pelvic renal rupture. In the present study, pre- and post-treatment radiological imaging findings of a case with renal pelvis rupture due to right ureter stone and the use of gray scale and color Doppler ultrasonography in the diagnosis has been discussed.

Spontaneous Rupture of Renal Pelvis

Spontaneous renal pelvis rupture is a rare situation. It is nearly always related to underlying renal abnor-malities caused by calculus, infection, tumor or pregnancy, resulting in hydronephrosis. In some situations, it is iatrogenic, such as fluid overload during diagnostic or therapeutic interventions. Here, we present a case of spontaneous renal pelvis rupture with no predisposing factor found.

Spontaneous Rupture of Renal Pelvis during Postobstructive Diuresis

A case of spontaneous rupture of the renal pelvis during postobstructive diuresis following spontaneous relief of anuria in a patient with postpyelolithotomy retroperitoneal fibrosis, is described. The unusual etiopathological setting which predisposed to the occurrence of such a rare phenomenon and its treatment implications are discussed.
