Parenchymal renal rupture due to an obstructive ureteric calculus in an incompletely duplicated renal pelvis and ureter.

Introduction: Parenchymal renal rupture due to a ureteric calculus is extremely rare and an emergency. Case presentation: A 54-year-old man was brought to the emergency room with left back pain without trauma. Computed tomography showed left parenchymal renal rupture with an incompletely duplicated renal pelvis, ureter, and an 11-mm ureteric calculus in the ureterovesical junction. A ureteral stent was placed, and the patient was treated conservatively as his vital signs were stable. We performed transurethral lithotripsy after resolution of the perirenal hematoma. Conclusion: To best of our knowledge, this report is the first to present a case of parenchymal renal rupture due to a ureteric calculus in an incompletely duplicated renal pelvis and ureter. Ureteric calculus within an incompletely duplicated renal pelvis and ureter is at risk of parenchymal renal rupture. Therefore, the aggressive treatment of ureteric calculus could be important.

A Spontaneous Renal Calyceal Rupture Mimicking Physiologic Changes of Pregnancy and Other Common Pathologies.

A spontaneous renal calyceal rupture in pregnancy is extremely rare and can be challenging to identify as its presentation can mimic other more common diagnoses, which can lead to a delay in management. Here, we describe an unusual case of renal calyceal rupture in a 24-year-old G2P0010 female with pregnancy at 26.5 weeks gestation age (WGA) who was admitted to the antepartum ward due to left flank pain and uterine contractions. A renal sonogram was performed, which revealed severe left hydronephrosis and the absence of the ipsilateral ureteral jet. Urinalysis was within normal limits, and her renal function was preserved. Laboratories were remarkable for elevated liver enzymes. Finally, an abdominopelvic MRI revealed the culprit, a calyceal rupture. Once the diagnosis was clear, a double J-stent was inserted using limited fluoroscopy with the goal of reducing intrarenal pressure and decreasing disease morbidity. The patient's symptoms significantly improved after double J-stent placement and resolved the following day. The patient further developed preeclampsia with severe features, which has previously been documented to occur in pregnant patients with renal tract ruptures. The diagnosis of a renal calyceal rupture in pregnancy is not straightforward, in part because of a lack of awareness of this pathology. Nevertheless, early identification can prevent unnecessary interventions and adverse outcomes. Its diagnosis can be made with MRI, and its management with ureteral stent placement shouldn't be delayed, and its association with preeclampsia should be further explored.

Delayed bilateral spontaneous renal rupture after surgery for unilateral upper ureteral calculi: a case report.

Spontaneous renal rupture is a rare clinical condition characterized by spontaneous bleeding in the renal subcapsular and perinephric spaces in patients without a history of trauma. It occurs mainly in pathologic kidneys and after some renal surgeries. We report a 40-year-old male patient admitted with a diagnosis of gallstones with cholecystitis due to fever and abdominal pain after unilateral ureteral calculi. The patient developed delayed right renal rupture hemorrhage during treatment, controlled after selective arterial embolization (SAE). Still, the patient developed spontaneous left renal rupture due to a systemic inflammatory response. Finally, the patient's life was saved after several selective embolizations of the renal artery. We retrospectively analyzed this case to improve our understanding of the disease.

Retroperitoneal Hemorrhage Due to Spontaneous Renal Rupture as the First Presentation of Antiphospholipid Syndrome: A Case Report.

Spontaneous renal rupture (SRR) with retroperitoneal hemorrhage is an extremely rare medical emergency and is rather challenging for the surgical team. Management of SRR often requires surgical intervention and nephrectomy as it is life-threatening. Antiphospholipid syndrome (APLS) is an autoimmune disease that affects several organs, including kidneys, causing significant abnormalities. Current data suggest that APLS can result in renal artery stenosis, renal vein thrombosis, arterial hypertension, thrombotic microangiopathy, and antiphospholipid syndrome nephropathy where there is renal involvement. Here, we report the case of a 49-year-old man who presented to the Emergency Department with sudden-onset abdominal pain in the context of retroperitoneal bleeding due to SRR. The patient developed hemodynamic instability and underwent a total nephrectomy. The surgical specimen revealed APLS-related lesions. Serological tests confirmed the diagnosis of APLS, which was managed with acenocoumarol and hydroxychloroquine. Since then, he has not experienced any thromboembolic or hemorrhagic episodes. This article aims to present for the first time a case of SRR as the first presentation of APLS as well as to analyze the possible associated mechanisms.

Spontaneous renal rupture due to renal calculi: A case report and literature review.

Spontaneous renal parenchymal rupture is a rare clinical emergency. The formation of benign and malignant tumors is the most common underlying cause of spontaneous rupture of renal parenchyma. To the best of our knowledge, 15 cases of renal parenchymal rupture have been reported to date. This report describes a rare case of renal parenchyma rupture in the lower left kidney caused by kidney calculi. Furthermore, previously published cases and articles were reviewed. The patient underwent four extracorporeal shockwave lithotripsy procedures within 2 years. The renal parenchyma rupture caused by the stones was successfully treated by removing the stones and repairing the kidney. However, a large hematoma was discovered around the lower pole of the left kidney, suggesting the possibility of a renal tumor. Therefore, radical nephrectomy was performed. Postoperative pathology revealed the lesion to be consistent with an intrarenal stone, where no malignancy, infection or vascular disease was observed. The present case highlights the requirement to also take into account the patient's clinical history in cases where imaging cannot completely identify the underlying cause of renal parenchymal rupture. Accurate identification of the underlying etiology of spontaneous renal rupture may determine the best treatment for the patient. The purpose of the present report is to facilitate the identification of the disease and reduce the rate of clinical misdiagnosis.

Spontaneous renal tract rupture from obstructing vesico-ureteric junction calculus.

Spontaneous or non-traumatic rupture of the renal tract is an infrequent presentation, and it is most frequently caused by ureteric obstruction. Rupture could occur at any level of the upper urinary tract. However, it is most common at the renal calyces and complications that could arise include; urinoma, and or hematoma collection which could progress to abscess formation and sepsis. We report a 77-year-old male patient who attended the emergency department following referral from his general practitioner with a 6-day history of progressively worsening left sided abdominal pain. Due to his co-morbidities, presenting blood pressure and age, he was suspected of having an aortic dissection or ruptured abdominal aortic aneurysm and subsequently had a CT (computed tomography) Angiogram. This showed extravasation of contrast from the left kidney with a 12 mm obstructing vesico-ureteric junction calculus necessitating urgent urology referral and prompt review. He was worked up for a ureteric double J stent insertion, however, the procedure was unsuccessful due to complex multiple urethral strictures. The patient subsequently had a nephrostomy inserted and was planned for optical urethrotomy, rigid cystoscopy, rigid/flexible ureteroscopy, and laser stone fragmentation of left obstructing vesico-ureteric junction calculus.

Spontaneous intraperitoneal renal rupture with urinoma formation in the fetus.

Spontaneous intraperitoneal renal rupture with urinoma formation in fetuses is an unusual condition that is caused by upper or lower urinary tract obstruction. We report the case of a neonatal male infant who presented with a spontaneous intraperitoneal right renal rupture accompanying ipsilateral ureterovesical junction obstruction (UVJO). Fetuses with UVJO accompanying contralateral multicystic dysplastic kidney should be observed carefully because of the risk of spontaneous renal rupture.

Klebsiella pneumoniae infection secondary to spontaneous renal rupture that presents only as fever: A case report.

BACKGROUND: Spontaneous renal rupture is a rare disease in the clinic. The causes of spontaneous renal rupture include extrarenal factors, intrarenal factors, and idiopathic factors. Reports on infection secondary to spontaneous renal rupture and the complications of spontaneous renal rupture are scarce. Furthermore, there are few patients with spontaneous renal rupture who present only with fever. CASE SUMMARY: We present the case of a 52-year-old female patient who was admitted to our hospital. She presented only with fever, and the cause of the disease was unclear. She underwent a contrast-enhanced computed tomography (CT) scan, which showed that the left renal capsule had a crescent-shaped, low-density shadow; the perirenal fat was blurred, and exudation was visible with no sign of calculi, malignancies, instrumentation, or trauma. Under ultrasound guidance, a pigtail catheter was inserted into the hematoma, and fluid was drained and used for the bacterial test, which proved the presence of Klebsiella pneumoniae. Two months later, abdominal CT showed that the hematoma was absorbed, so the drainage tube was removed. The abdominal CT was normal after 4 mo. CONCLUSION: Spontaneous renal rupture due to intrarenal factors causes a higher proportion of shock and is more likely to cause anemia.

Multiple renal ruptures after flexible ureteroscopic lithotripsy with holmium laser.

The authors present a case report of multiple renal ruptures after flexible ureteroscopic lithotripsy (FURL) with holmium laser. Multiple renal ruptures following flexible ureterorenoscopy have not been reported so far. The etiology remains unclear. We like to share this case to make urologists aware of this unusual complication and discuss possible causes and therapeutic approaches.

Perinephric urinoma following spontaneous renal rupture in the third trimester of pregnancy: a case report and brief review of the literature.

BACKGROUND: Spontaneous formation of urinoma is a rare condition, especially for pregnant women. We report a patient in the third trimester of pregnancy with a spontaneous renal rupture who then develops a urinoma from urine leaking into the perinephric space. CASE PRESENTATION: A 23-year-old primagravida was diagnosed with a spontaneous renal rupture and acute left loin pain accompanied by hematuria when she was 35 weeks pregnant. A sub-capsular perinephric cyst then developed to a size of 319 × 175 × 253 mm, and because of discomfort to the patient, we performed Cesarean section. After a healthy male newborn was delivered, fluid was suctioned from a large perirenal cyst that had an estimated size of 300 × 200 × 300 mm. A percutaneous nephrostomy tube was left in the cyst until CT showed no remaining fluid. In the six-month follow-up, the patient showed no perirenal extravasation according to an ultrasound scan, and the urine analysis and renal function tests were normal. CONCLUSION: Close follow-up should be recommended for the patient who has renal rupture after conservative therapy, especially for pregnant woman. CT or MRI should be considered in addition to utilizing ultrasound in the management of pregnant women who present with urinomas. Percutaneous nephrostomy is suggested as an appropriate treatment for large urinomas.

Spontaneous Subcapsular Renal Haematoma : A Case Report.

Spontaneous subcapsular renal haematoma is a rare condition with wide range of presentation; it poses a dilemma for diagnosis and management. We present a case of 38-year-old female who presented with right flank pain (continuous, dull aching) for a week with right renal angle tenderness and high blood pressure (though she was not known hypertensive). On imaging, there was right renal subcapsular collection. She did not respond to conservative management except that her blood pressure was controlled with single drug Angiotensin Converting Enzyme (ACE) inhibitor. Right double J stent was placed (in view of urinoma) and patient was followed for six weeks. Repeat computed tomography scan showed persistence of right renal subcapsular collection but the cause was not found. Except hypertension, no definitive cause for the condition could be found. Patient was intervened surgically with right subcostal exploration and subcapsular haematoma was found and drained. Patient was asymptomatic thereafter.

Sudden onset flank pain: Spontaneous renal rupture.

BACKGROUND: Undifferentiated abdominal pain is a common condition encountered in the emergency department. While a patient's age, risk factors, and comorbidities often aid in risk stratification and guide emergency department evaluation, atypical presentations of serious disease may still occur suddenly in young otherwise healthy patients. CASE REPORT: In this vignette we discuss a case of spontaneous, atraumatic renal rupture with large retroperitoneal hemorrhage (Wunderlich's Syndrome) in a 22year old male. DISCUSSION: Emergency physicians regularly encounter uncommon causes of abdominal pain. Wunderlich's syndrome is rare but proper understanding of the disease process will aid in decision making and improve disposition and outcomes for patients. Likely presentations and risk factors for atraumatic renal rupture will be discussed as well as ED management and definitive treatment options.

[SPONTANEOUS RENAL RUPTURE TREATED BY TRANSCATHETER ARTERIAL EMBOLIZATION: A CASE REPORT].

We describe our experience with a case of spontaneous renal rupture. A 43-year-old man visited our hospital with a chief complaint of left back pain with no identifiable triggering factors. A CT scan showed a rupture involving the left renal parenchyma and hematoma around the kidney. However, there were no apparent causes of the renal rupture, such as tumors and vascular lesions. Based on these findings, he was diagnosed with spontaneous renal rupture. Due to progression of anemia during the course, he underwent transcatheter arterial embolization of the kidney. He continues to undergo imaging examinations on a regular basis and has shown no development of apparent neoplastic lesions for 13 months.

Spontaneous subcapsular renal hematoma: A case report and review of literature.

Spontaneous subcapsular renal hematoma is not a common entity. We report a 38-year-old lady presenting with sudden onset right flank pain with uncontrolled hypertension and she was found to have subcapsular collection in the right kidney on ultrasonography. Finding was confirmed on computed tomography. Except hypertension, no particular cause for the condition could be found. Symptoms and size of the collection decreased on conservative treatment. They completely disappeared on ultrasonography at 6 months follow-up. She was asymptomatic at 18 months follow-up.

Fatal Renal Rupture as a Rare Complication of Percutaneous Nephrolithotomy / 대한마취과학회지

Percutaneous nephrolithotomy (PNL) is a safe and effective procedure commonly performed to remove renal stones. Although PNL is associated with low morbidity, unexpected complications may occur. We describe here a 44-year-old male patient with recurrent renal stones who experienced a renal rupture and massive bleeding following PNL. Left nephrectomy and intensive treatment did not improve the patient's condition, and he died 14 days later as a result of multi-organ failure.

Spontaneous Renal Rupture in Patients on Chronic Hemodialysis / 대한신장학회잡지

BACKGROUND: Because of high incidence of acquired renal cyst and renal malignancy, it is suggested that spontaneous renal rupture more frequently occurs in patients receiving long-term hemodialysis than general population. This study was performed to evaluate the clinical characteristics of spontaneous renal rupture in hemodialysis patients. METHODS: This retrospective study enrolled 12 hemodialysis patients who developed spontaneous renal rupture. We investigated primary renal disease, duration of dialysis, clinical symptoms and signs, radiologic findings, treatment modalities, and histologic findings. RESULTS: The mean age of the patients was 54+/-10 years old and the number of male was 9. Primary renal disease consisted of autosomal dominant polycystic kidney disease (PCKD) (n=5), chronic glomerulonephritis (n=2), diabetic nephropathy (n=1), hypertensive nephropathy (n=1), unknown cause (n=3). Presenting symptoms and signs were sudden onset of flank pain in 9 patients and gross hematuria with mild flank pain in 3 patients. Mean duration from initiation of hemodialysis to development of spontaneous renal rupture was 53+/-36 months. Abdominal computed tomography showed subcapsular or perinephric hematoma in all patients. Of the 7 non-PCKD patients, 6 patients had multiple acquired renal cysts. Surgical exploration was undertaken in 9 patients. Pathologic examination demonstrated small sized-renal cell carcinoma in 2 of 9 patients. Three patients were only treated with conservative management including blood transfusion. All 12 patients recovered without recurrence. CONCLUSION: This study demonstrated that genetic or acquired renal cyst was an important cause of spontaneous renal rupture in hemodialysis patients and presenting manifestations were sudden onset of flank pain and gross hematuria.

Spontaneous Rupture of the Kidney Due to Metastatic Choriocarcinoma during Pregnancy / 대한비뇨기과학회지

A spontaneous rupture of the kidney due to a metastatic choriocarcinoma, which is associated with a normal pregnancy, is very rare. A 33-year-old female patient presented with sudden colicky right flank pain on the 5th day after a Cesarian Section. An abdominal CT scan showed evidence of a right renal rupture with a perirenal hematoma. Under the impression of a spontaneous rupture of right kidney, an exploratory laparotomy with a radical nephrectomy was performed. The pathologic findings revealed a renal parenchymal rupture due to a metastatic choriocarcinoma.
