Bladder Sparing Extirpation of Pelvic Mass With Ureteral Reimplantation: A Case Report on Pelvic Lipomatosis Treatment.

Pelvic lipomatosis is a proliferative disease characterised by excessive fat growth in retroperitoneal space leading to inadequate bladder drainage and ureteral compression. Cystitis glandularis, cystitis cystica, or cystitis follicularis can be found in the majority of patients with the disease. We report a case of a 63-year-old man diagnosed outside our hospital with pelvic lipomatosis after finding a pelvic mass behind the bladder causing severe bilateral hydronephrosis. A bladder-sparing excision of the pelvic lipomatosis mass with bilateral ureteric reimplantation was performed, thereby avoiding the need for urinary diversion. Our case supports the hypothesis that pelvic fat mass extirpation and ureteral reimplantation is an effective surgical treatment strategy for pelvic lipomatosis.
