A Comparison of Treatment Outcomes of Bladder Stone between Open Suprapubic Cystolithotomy and Transurethral Cystolithotripsy in Chomthong Hospital, Chiang Mai

Abstract

            The research aimed to compare the treatment outcome and complication of bladder stone surgery between open suprapubic cystolithotomy and transurethral cystolithotripsy in Chomthong hospital, Chiangmai. This study was retrospective review in patients who underwent bladder stone surgery from March, 2008 to February, 202. The basic information was analyzed using the descriptive statistic. The differences between groups were analyzed using the Independent t–test, Mann–Whitney U test และ Chi–square test. The propensity score was used to eliminate the influence of confounding factors.     

            There were totally 276 patients with bladder stone, 52 had open surgery and 224 had transurethral procedure. The complications were significantly more common in open suprapubic cystolithotomy than transurethral cystolithotripsy included fever, wound infection, urine leakage and vesico–cutaneous fistula (p < 0.001). Transurethral cystolithotripsy had the duration of hospital stay, postoperative indwelling urinary catheter, operative time and postoperative pain score significantly less than those with open suprapubic cystolithotomy (p < 0.001). The bladder stone size and stone free rate between two methods not different. T he stone free rate in open suprapubic cystolithotomy and transurethral cystolithotripsy were 100% and 96.43%, respectively.

            The stone free rate and recurrent rate in 1 year in bladder stone treatment by transurethral cystolithotripsy did not different from open suprapubic cystolithotomy but the transurethral cystolithotripsy method, had fewer duration of hospital stay, operative time, postoperative indwelling urinary catheter, postoperative pain score and complications.
