Demonstration of 2 unusually large pelvic lymphocysts by lymphangiography

Lymphocele after pelvic lymphadenectomy for urologic cancer

Pelvic lymphadenectomy is used widely for staging prostatic or bladder carcinoma. In 9 of 187 patients (4.7 per cent) who underwent bilateral pelvic lymphadenectomy for urologic cancer pelvic lymphocele diveloped. The management of these patients is presented along with review of causes, clinical features, diagnosis, and treatment. Pelvic CT scan is a noninvasive modality which aids in the diagnosis of this complication. Minidose heparin used for prophylaxis of thromboembolic complications may increase lymphocele formation.

Perivesical mass and vertical bladder caused by massive prostatic enlargement

Massive prostatic enlargment may present with the radiographic appearance of a perivesical mass and pear-shaped bladder. An explanation of this appearance, based on the compouted tomographic findings, is offered. We discuss the differential diagnosis.

Lymphocyst: ultrasound diagnosis and urologic management

Three cases of lymphocysts occurred in a series of 97 patients undergoing extension pelvic urological operations, an incidence rate of 3.1 per cent. This is the first report of this complication after urological lymphadenectomy. Awareness of the entity is important to urologists since lymphatic staging operations for prostate and bladder carcinoma are widely used to help plan definitive therapy. Athough this complication is rare after renal transplantation it may cause significant interference with graft function. The etiology, symptoms, findings, diagnosis and treatment of this condition are reviewed. Echography is presented as an ideal technique to diagnose the condition and to guide in its management.
