title: Ultrasonography versus urography as preoperative investigation prior to hysterectomy.
abstract: Ultrasonography (US) has been compared with urography (IVU) as a preoperative investigation prior to hysterectomy in 62 patients. In 38 patients the urinary tract was deemed normal by both US and IVU. US and IVU coincided in varying degrees of hydronephrosis in 8 patients and disagreed in one. Of 5 double ureters, US missed 2. IVU showed expansile lesions in 5 kidneys where US showed benign cysts. No severe contrast media reactions were observed. We recommend that preoperative urography should be replaced by preoperative ultrasonography when a screening examination of the upper urinary tract morphology is deemed necessary prior to hysterectomy.
