Spontaneous retroperitoneal hemorrhage secondary to subcapsular renal hematoma: MRI findings.

Spontaneous retroperitoneal hemorrhage is a rare intraabdominal bleeding. In this report we present a case of a nontraumatic retroperitoneal hemorrhage secondary to spontaneous subcapsular renal hematoma. A 54-year-old patient who was under warfarin therapy, developed subcapsular right renal hematoma. Subcapsular and retroperitoneal hemorrhage were low signal on T1- and T2-weighted images consistent with acute stage of blood. The source of subcapsular hematoma was shown to be the rupture of hemorrhagic renal cyst on MRI. Extension of hemorrhage into the retroperitoneal space anterior to right psoas muscle was also successfully shown on MRI. Patient underwent nephrectomy and retroperitoneal blood was evacuated.

Removal of urolume endoprosthesis using holmium:YAG laser.

A potential complication of UroLume endoprosthesis is migration, which may necessitate removal of the stent. Stent removal may be associated with complications such as urethral injury, bleeding, and external sphincter trauma. We report a patient in whom a holmium:yttrium-aluminium-garnet (Ho:YAG) laser was used to cut the UroLume endoprosthesis into fragments, which led to easy and uneventful stent removal.

Bladder involvement in Behçet's syndrome.

PURPOSE: We report our clinical experience with Behçet's syndrome and bladder involvement. MATERIALS AND METHODS: From April 1991 through July 1996, 7 men and 1 woman 25 to 53 years old with Behçet's syndrome were evaluated for lower urinary tract symptoms (7) or hematuria (1). Of 8 patients 5 had neurological involvement. Evaluation consisted of history, physical examination, urinalysis and urine culture, excretory urography, urodynamic studies, urethrocystoscopy, bladder biopsies and histopathological examination. RESULTS: Cystoscopy revealed bladder ulcer in 1 patient and an indurated, hypervascular lesion in another with bilateral hydronephrosis. The most common urodynamic finding was detrusor overactivity. Of 4 patients with poor compliance 1 had additional sphincteric deficiency. Common histopathological features were moderate and marked thickening of bladder vessel walls. Lymphocytic vascular reaction was present in 2 patients and lymphocytic vasculitis in 1. Clamshell augmentation ileocystoplasty was performed in 3 patients, including 1 who also underwent a sphincter enhancement procedure. The remaining 5 patients received various nonsurgical treatment. CONCLUSIONS: Various types of voiding dysfunction relating to bladder and sphincteric components in both phases of micturition can be seen in Behçet's syndrome. Voiding dysfunction can be due to either neurological or direct bladder involvement. Augmentation ileocystoplasty is a good treatment option for Behçet's syndrome with severe bladder involvement.
