Hypertonic Saline Injection For Urinary Incontinence

Patients were in the lithotomy position for the procedure. After preparation, topical Lidocaine gel was instilled around the meatus and a 16 F probe was attached. The catheter balloon was inflated to localize the bladder neck and to ensure that injections were performed in the correct anatomical plane. Hypertonic saline (10% NaCl) was injected to the alignment of the urethral meatus in the order of 3-6-9-12 hours of the clock (5 cc to each site, totaling 20 cc). Syringes with 27 Gauge (0.40 mm) outer diameter were used to ensure controlled injection. Since the female urethra is about 4 cm in length, the needle was advanced about 3 cm. Due to the possibility of significant pain with hypertonic saline, 2 cc of Lidocaine hydrochloride was added into the solution.
