Spontaneous intraperitoneal extravasation of urine is rare. Urinary ascites occurs mostly in patients with the common primary obstructive lesion being posterior urethral valves. The second most common cause of urinary ascites is hydronephrosis due to congenital ureteropelvic junction obstruction. We report a case of urinary ascites with urinoma resulting from a ureteropelvic junction obstruction in an infant.

Spontaneous intraperitoneal extravasation of urine is rare. Perirenal urinoma may develop when obstruction to urinary flow creates sufficient back pressure to produce extravasation of urine. Urinary ascites most commonly indicate a disruption to the integrity of the urinary tract. We report a case of urinary ascites with urinoma resulting from an ureteropelvic junction obstruction in a neonate.

Retroperitoneal fibrosis is a fibroproliferative process involving the retroperitoneum. It may be idiopathic or can be caused by methysergide ingestion, perianeurysmal inflammation, a leaking aneurysm, urinoma or irradiation. The symptoms and signs of retroperitoneal fibrosis are variable, and for diagnosis, imaging is therefore essential. The typical imaging finding is a fibrotic lesion in front of the lower vertebrae with ureteral obstruction. Atypical lesions, however, may occur in other parts of the retroperitoneum. The aim of this report is to describe the clinical features and various imaging findings of etroperitoneal fibrosis.

Spontaneous ureteral rupture is rare, and refers to leakage in the absence of prior ureteral manipulation, external trauma, previous surgery, or any destructive kidney disease. It presents a major diagnostic challenge due to the diversity at presentation. Here, we present a rare case of spontaneous ureteral rupture in a 62-year-old man with a history of fungal pyonephrosis (Candida) on maintenance hemodialysis, causing a large infected urinoma and abscess and a review the literature.

Ureteral injuries after external violence are rare, occurring in less than 4% of penetrating traumas and 1% of blunt traumas. Most of the ureteral injuries are traumatic in origin and tend to occur as a result of shootings, or stabbings, or during various intraabdominal or retroperitoneal operations. Most are localized in the upper one third of the ureter. Ureteral injury after blunt trauma is rare and can be missed because patients often do not present hematuria. Therefore, in case of blunt trauma exhibiting flank pain, fever, abdominal distention, and leukocytosis, an abdominal CT scan and other diagnostic tools must be used. We describe a case of blunt abdominal trauma that resulted in a ureteral injury with urinoma.

Urinary tract dilation is one of the most common side effects during pregnancy. This is primarily a physiologic phenomenon that is typically more prominent on the right side, and it is caused by hormonal changes and mechanical obstruction. Occasionally, urinary tract dilation leads to more serious urinary tract problems such as infection, obstructive renal failure and urinomas. Urinomas are also known as pararenal pseudocysts, and they generally occur as a result of urinary system disruption, but they only rarely occur with pregnancy. We report here on an unusual case of extremely large bilateral perirenal urinomas that were detected during the postpartum period. This was successfully resolved by percutaneous drainage and ureteral stents.

Ureteroileocecal sigmoidostomy is a method of continent urinary diversion which can protect the upper urinary tact from urinary reflux and infection, without external collecting devices and concomitant catheterization as in other forms of urinary diversion. Recently, we experienced 7 cases of ureteroileocecal sigmoidostomy in bladder cancer. Of them, 3 cases of immediate complications (retroperitoneal urinoma, wound disruption and ureteral obstruction ) were developed, but they could be corrected with prolonged placement of rectal tube or corrective surgery. And then, ureteral reflux, upper urinary tract infection and incontinence were not observed. So, ureteroileocecal sigmoidostomy is an attractive method of continent urinary diversion in selected cases.

Urinothorax occurs when urine leakes into thoracic cavity and it was first reported by Correie in 1968. The mechanism of its occurrence is an accumulation of urine in thoracic cavity by retroperitoneal urinoma formed by urinary tract obstruction or trauma. Retroperitoneal inflammation, malignant neoplasm, kidney transplantation, and kidney biopsy can also induce urinothorax. The diagnosis of urinothorax may be delayed due to its rare incidence rate, but if diagnosis is confirmed the treatment is possible by urinary diversion. We report our experience of a case of urinothorax associated with retroperitoneal urinoma followed by blunt renal trauma with review of literatures.

PURPOSE: This study is designed to evaluate the usefulness of (99m)Tc-MAG3 renal scan in the diagnosis of early surgical complication of renal transplantation comparing with that of ultrasonography. METHODS: 203 renal transplantations, from January 2000 to December 2004, were studied retrospectively. (99m)Tc-MAG3 renal scan and ultrasonography were performed routinely for evaluation of allograft kidney at postoperative day 3, 7, 14 and 21 or 28 respectively. RESULTS: Thirteen early surgical complications (6.4%) from 203 recipients were developed during the first one month after transplantation. Six cases of urological complications were noticed. And six cases of hematoma and one case of lymphocele were also developed. (99m)Tc-MAG3 renal scan showed abnormality in ten cases (76.9%) of thirteen early surgical complications. (99m)Tc-MAG3 renal scan revealed all of six urologic complications (100%), and four of six hematomas (66.7%). But one lymphocele was not detected by (99m)Tc-MAG3 renal scan. Ultrasonography showed abnormal findings in eight cases of 13 early surgical complications (61.5%): one of four urine leakage (25%), two of two urinomas (100%), four of six hematomas (66.7%), and one lymphocele (100%). CONCLUSION: (99m)Tc-MAG3 renal scan is more sensitive than ultrasonography in detection of earlysurgical complications of renal transplantation. Then (99m)Tc-MAG3 renal scan is useful test for screening and follow-up of early surgical complications after renal transplantation.
