This study compared the efficacy and safety of BATV and BH for managing KC, indicating that BATV is superior in improving bladder capacity and urodynamic outcomes compared to BH.
Background: To illustrate the bladder autoaugmentation by transurethral vesicomyotomy (BATV) and compare the efficacy and safety of BATV to bladder hydrodistention (BH) for managing ketamine cystitis (KC). Methods: We retrospectively analyzed clinical data for 53 patients with KC who received surgical intervention between 2014 and 2019 at our hospital. Of these, 41 (77.4%) underwent BH and 12 (22.6%) were subjected to BATV, with a minimum of 1-year follow-up. These groups were compared with reference to urodynamic parameters, subjective symptom scores as well as all complications. Results: Both groups were matched in age, addiction time, preoperative urodynamic parameters, postvoid residual urinary volume (PVR), and symptom scores. All urodynamic parameters including maximum cystometric capacity (MCC), maximum detrusor pressure (P-det max), compliance, maximum urinary flow rate (Q(max)) and symptom scores had improved significantly in two groups whether at 3 or 12 months. Moreover, the MCC was significantly increased after BATV than BH, at a mean [standard deviation (SD)] of 281.0 (25.7) vs. 213.5 (35.6) mL (P<0.001) at 12-month follow-up. The Q(max) and the Pelvic Pain and Urgency/Frequency (PUF) symptom score were still noted better in the BATV group at 3 months after surgery. Additionally, patients in both groups had similarly low rates of complications. Conclusions: BATV is superior to BH with increased bladder capacity and urodynamic outcomes, although showing equivalent in symptom relief and a similar rate of complications.
