Table 2 Study characteristics and results
Author | Study Design | Location | Sample Numbers | Exposure | Comparator | Outcome | Results |
|---|---|---|---|---|---|---|---|
Pyun et al. (2017) [12] | Retrospective Cohort | South Korea | 227 patients | Patients with detrusor dysfunction (56 with detrusor overactivity and 33 with detrusor underactivity) that underwent HoLEP (n = 89) | Patients only with bladder outlet obstruction (BOO) (n = 138) | IPSS, Quality of Life, Qmax, and PVR | Patients in BOO-only group had greater IPSS improvement than detrusor dysfunction group (p = 0.023). Post-operative IPSS voiding (4.5 vs 7.0) and Qmax (18 vs 13.7) is significantly better in BOO-only group than detrusor underactivity group |
Choi et al. (2011) [13] | Retrospective Cohort | South Korea | 371 patients | Patients with bladder outlet obstruction (BOO) and detrusor underactivity (DU) that underwent PVP (n = 132) | Patients with bladder outlet obstruction (BOO) that underwent PVP (n = 132) | IPSS, Qmax, and PVR | There is no significant difference in group with DU or not in outcome parameter at 1 and 12 months after the operation |
Cho et al. (2016) [14] | Retrospective Cohort | South Korea | 1423 patients | Holmium laser enucleation of the prostate (HoLEP) divided into groups without detrusor underactivity (B1) (n = 329) or with detrusor underactivity (B2) (n = 423) | Photoselective vaporisation of the prostate (PVP) divided into groups without detrusor underactivity (A1) (n = 239) or with detrusor underactivity (A2) (n = 432) | IPSS, uroflowmetry component (Qmax and PVR) and prostate-specific antigen (PSA) | After one month follow up, A1 and BI group had higher increases in maximum flow rate than A2 or B2. B2 had better improvements in maximum flow rate and IPSS score than A2 |
Woo et al. (2017) [15] | Retrospective Cohort | South Korea | 56 patients | Holmium laser enucleation of the prostate (HoLEP) n = 24) | Transurethral resection of prostate (TURP) (n = 32) | IPSS, Qmax, and PVR | After six months follow up, HoLEP group subjects had higher Qmax (p = 0.005) and lower PVR values (P = 0.022) than TURP group |
Jaeger et al. (2014) [16] | Retrospective Cohort | United States of America | 103 patients | Holmium laser enucleation of the prostate (HoLEP) (n = 72) | Photoselective vaporisation of the prostate (PVP) (n = 31) | AUA Symptom Index (AUASI), Qmax, PVR, catheter-free rate | After six months follow up, HoLEP group subjects (99%) had higher catheter-free rate (p < 0.01) than PVP group (74%). There was improvement in AUASI, maximum urinary flow rate and PVR in both groups |
