Introduction:
We report outcomes in men with impaired detrusor contractility (IDC) treated with KTP laser ablation (KTPLAP) or transurethral resection of the prostate (TURP).
Materials & Methods:
This was a retrospective study of consecutive patients with IDC who underwent KTPLAP or TURP. IDC was defined as bladder contractility index <100 or detrusor contraction of insufficient duration to empty bladder. Pre-operative uroflow(Qmax), post-void residual volume(PVR), videourodynamics, and cystoscopy were obtained. Post-operative Qmax, PVR, clean intermittent catheterization(CIC) need, and Patient Global Impression of Improvement(PGII) score were obtained.
Results:
56 men aged 29-91 years (mean=67) were included. Mean preop BCI, BOOI, and PVR for entire cohort was 51(SD=30), 31(SD=30), and 670(SD=559) respectively. Mean preop IPSS and bladder capacity for the entire cohort was 14(SD=8) and 904mL (SD=605mL) respectively. 5(96%) subjects were available at 1 year follow-up and 53/56(95%) subjects completed PGII. 41(73%) had successful outcomes (PGII score=1 in 20, 2 in 21). 6(11%) had little to no improvement (PGII score=3 in 2, 4 in 4), 6(11%) were worse (PGII score=5 in 1, 6 in 3, 7 in 2) and 11 still required CIC. Pre- and postop data is shown below.
Conclusions: 80% of patients with IDC who underwent KTPLAP/TURP had excellent outcomes based upon PGII and Objective improvement in PVR, Qmax, and need for CIC. TURP/KTPLAP is viable for properly selected patients with IDC.
