  1. Instrumental Exam, Interventional Urology

  2. Instrumental Examination • Exploartion of urethra with a catheter or other instruments is a valuable diagnostic measure. • Passage may be blocked by a stricture or tumor • Spasm – makes passage difficult • Residual urine is common in bladder neck obstruction, cystocoele, neurogenic bladder. • Residual urine is absent with urethral stricture

  3. Cystoscopy Cystoscopy is a procedure that uses a flexible fiber optic scope inserted through the urethra into the urinary bladder. The physician fills the bladder with water and inspects the interior of the bladder. The image seen through the cystoscope may also be viewed on a color monitor and recorded on videotape for later evaluation.

  4. Interventional Uroradiology • In the presence of a true obstruction: A. Whitaker test • Percutaneous insertion of a canula into the renal pelvis with perfusion of contrast at a rate of 10 ml/minute and simultaneous recording of pressure in the renal pelvis and bladder to identify the presence of obstruction in doubtful cases. • In children, the examination is performed under general anaesthetic and instead of a canula two fine needles are inserted The infusion of contrast allows a simultaneous antegradepyelography B. Isotope Renagam
