Catheterisation should not be done in case of acute retention of urine due to -: (A) Benign prostatic hyperplasia (BPH), (B) Ca prostate, (C) Stricture urethra, (D) All
Answer is C. Ans. is 'c' i.e. Stricture urethra In cases of urethral stricture, if a patient has gone into retention because of a urethral stricture, the urethra will be too narrow to allow even a tiny catheter to pass safely. Urethral rupture is a relative conraindication of catheterisation, because injudicious urethral catheterisation will conve a paial tear into a complete transection of the urethra.
