URINARY OBSTRUCTION Urinary obstruction can be a presentation of benign or a serious condition. Obstruction can occur anywhere in the urinary tract: Kidneys, ureter (the tube between the kidney and the bladder), bladder, prostate (in men), urethra (the tube between the bladder and the outside) Signs and symptoms of urinary obstruction inability to pass urine (urinary retention) weak stream of urine interrupted stream blood in the urine pain in either flank (side) or in the back abdominal pain and/or swelling

Important in the etiology of cystitis.

ACQUIRED Primary or Secondary to retroperitoneal lesion that invade or compress the urinary passages – Urethral strictures secondary to infection or injury – Benign prostatic hyperplasia or prostatic CA – Vesical tumor involving the bladder neck or one or both ureteral orifices – Local extension of CA of prostate or cervix into the base of bladder occluding the ureters – Compression of the ureters at the pelvic brim by metastatic nodes from CA of prostate or cervix – Retroperitoneal fibrosis or malignant tumor – pregnancy Neurogenic dysfunction affects bladder Infection secondary to ureterovesical obstruction Severe constipation bilateral hydroureteronephrosis Elongation and kinking of the ureter secondary to vesicoureteral reflux
PROSTATIC CA Possible signs of prostate cancer include a weak flow of urine or frequent urination. Weak or interrupted flow of urine. Frequent urination (especially at night). Trouble urinating.

One-third of the cases are secondary to: malignancy medication (methysergide, hydralazine, beta blockers) aortic aneurysm certain infections.
