Presentation transcript:

Abnormal prostate and posterior urethra: cystograms and urethrograms Abnormal prostate and posterior urethra: cystograms and urethrograms. Upper left: Benign prostatic hyperplasia. Gross enlargement of prostate gland producing marked elevation (arrows) of the bladder base. The bladder shows small diverticula and slight trabeculation. Excretory urogram (cystogram) in a 65-year-old man with history of obstructive voiding symptoms. Upper right: Foreign body (eyeliner pencil cover) lodged in bladder and prostatic urethra, with urethrorectal fistula. Radiopaque medium enters rectum and sigmoid colon (S) through fistula (arrow) from prostatic urethra. Retrograde urethrogram in a 43-year-old man. Lower left: Rhabdomyosarcoma of prostate. Lobulated filling defects (large arrow) encroaching on widened prostatic urethra. Voiding cystourethrogram in a 5-year-old boy with voiding difficulties. Small arrow = penile urethra. Lower right: Posterior urethral valves. Marked dilatation and elongation of prostatic urethra (P), with reflux into prostatic ducts (straight arrow) secondary to posterior urethral valves (curved arrow) with bilateral vesicoureteral reflux into dilated ureters (U). Voiding cystourethrogram in a 10-day-old boy. Source: Chapter 6. Radiology of the Urinary Tract, Smith & Tanagho's General Urology, 18e Citation: McAninch JW, Lue TF.
