Seminal vesicle congestion as a cause of postprostatectomy dysuria.

A series of benign prostatic hypertrophy patients were routinely evaluated, including transrectal echography, before and at regular intervals following surgery. Five patients had persistent symptoms of dysuria at 14-30 months after surgery. There was no infection, residual urine or malignancy to explain their symptoms. The seminal vesicles (SVs) were severely dilated on transrectal echography, a finding which was definitely not present on initial examination. The patients were treated by transrectal echo-guided aspiration of the SVs by the perineal approach. The fluid aspirated was examined, and antibiotics were directly injected into the SVs. In 4 of the patients, there was a dramatic relief of symptoms with prolonged improvement. In only 1 case, following transurethral resection, there was but slight improvement. Dilated, obstructed SVs after prostatectomy, clearly diagnosed on transrectal echography, may be the cause of persistent irritative urinary symptoms. Treatment can be instituted by echo-guided aspiration of the fluid with simultaneous injection of a potent antibiotic, resulting in probable immediate relief.
