A 35-year-old female with chronic recurrent UTIs is admitted to the hospital for diagnostic testing of an upper urinary tract problem. You know that incomplete emptying of the bladder due to bladder outlet obstruction can cause what?
A) Hydronephrosis
B) Nephritic syndrome
C) Pylonephritis
D) Nephrotitis
Ans: A
Feedback: If voiding dysfunction goes undetected and untreated, the upper urinary system may be compromised. Chronic incomplete bladder emptying from poor detrusor pressure results in recurrent bladder infection. Incomplete bladder emptying due to bladder outlet obstruction (such as benign prostatic hyperplasia), causing high-pressure detrusor contractions, can result in hydronephrosis from the high detrusor pressure that radiates up the ureters to the renal pelvis. Therefore options B, C, and D are incorrect.
