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.

Idiopathic Spontaneous Renal Rupture

Spontaneous renal rupture is a rare, but important, clinical problem that heralds a variety of kidney abnormalities. Tumors are the most common cause, followed by vascular disease, infection, nephritis and blood dyscrasia. In some cases, no underlying abnormality of the kidney can be found. The patients usually present with an acute onset of flank pain, a tender mass, and common symptoms and signs of shock. In most cases rapid surgical intervention is necessary and nephrectomy remains the treatment of choice in cases of a ruptured tumor. A 47 year-old female, who had been in good health previously, was hospitalized because of a sudden onset of left flank pain for one day. There was no history of trauma. Physical examination revealed marked tenderness and guarding over the left flank abdomen. A perirenal hematoma on the left side was seen with abdominal sonography. Computerized tomography demonstrated a large perirenal hematoma and a kidney rupture caudally. Selective renal angiography demonstrated an active bleeding over the lower pole, so a coil embolization and nephrectomy were performed. The histological examination of the kidney revealed no underlying abnormality. We report a case of idiopathic spontaneous renal rupture, along with a literature review.

Two cases of spontaneous rupture of the kidney / 대한비뇨기과학회지

Spontaneous rupture of the kidney with subcapsular or perinephric hemorrhage usually occurs secondary to various kinds of underlying diseases such as benign malignant tumor. vascular disease and infection etc. We experienced 2 cases of spontaneous rupture of the kidney secondary to renal cell carcinoma in a 44-year-old female and adult Wilms' tumor in a 17-year-old male.

A case of adult Wilms' tumor associated with spontaneous renal rupture / 대한비뇨기과학회지

Wilms' tumor is composed of a mixture of epithelial, stromal and blastematous elements in varing proportions. Adult Wilms' tumor, unlike that of childhood is a rare disease. Spontaneous rupture of the kidney with subcapsular or perirenal hematoma also is rarely seen in malignant renal tumor. A case of adult Wilms' tumor in 65-year old female is here reported, associated with spontaneous renal rupture, which was treated with radical nephrectomy and chemotherapy (vincristine, actinomycin D and doxorubicin).

Two Cases of Spontaneous Rupture of the Kidney / 대한비뇨기과학회지

Two cases of spontaneous kidney rupture with literatural review was presented at first in Korea. 1) 56 years male patient and 25 years male patient admitted to our department of Urology through Emergency Room after onset of 2 and 1 day. after treatment at local clinic. 2) Chief complaints were one side flank pain which was followed by total gross hematuria. 3) Preoperative diagnoses were kidney rupture due to necrotic pelvic tumor in 56 years male and hypernephroma in 25 years male patient. 4) Operation was procedured at 8 days and 4 days after admission respectively. 5) The operative procedure were nephrectomy in both cases. 6) The pathological diagnoses were pelvis rupture due to renal stone and parenchymal rupture due to renal infarction in each case.
