[Predictive value of comprehensive preoperative evaluation for the outcome of TURP]

To evaluate preoperative comprehensive examinations of the IPSS-voiding to storage subscore ratio (IPSS-V/S), maximum urinary flow rate (Qmax), intravesical prostatic protrusion (IPP) and postvoid residual urine volume (PVR) in predicting the outcome of transurethral resection of the prostate (TURP) for BPH.

This retrospective study included 103 cases of BPH treated by TURP in Yixing People's Hospital from December 2018 to December 2019. The patients averaged 71.92 ± 7.73 years of age, with a mean prostate volume of (58.34 ± 15.59) ml, preoperative IPSS of 23.38 ± 3.36, voiding score of 14.38 ± 2.69, storage score of 9 (8－10), V/S ratio of 1.67 (1.43－1.88), Qmax of 7 (5－8) ml/s, IPP of 4 (0－5) mm, and PVR of (117.03 ± 20.51) ml. The TURP operations were completed by the same surgeon, with mean operation time of (83.65 ± 14.31) min and intraoperative blood loss of (55.32 ± 18.92) ml. The patients were followed up for 3 months after surgery for evaluation of the outcomes based on the IPSS and quality of life (QOL) scores.

The postoperative IPSS was significantly improved in all the patients compared with the baseline (5.36 ± 1.95 vs 23.38 ± 3.36, P < 0.05). Based on the criteria of IPSS < 7 and general satisfaction with QOL, satisfactory results were achieved in 71 (68.93%) of the patients (aged 71.04 ± 7.23 years, prostate volume: ［59.68 ± 15.79］ ml, IPSS: 23.87 ± 3.42, voiding score: 14.87 ± 2.34, storage score: 9 ［8－10］, V/S ratio: 1.67 ［1.47－1.86］, Qmax: 6 ［4－7］ ml/s, IPP: 5 ［0－6］ mm, PVR: 110.53 ± 17.69 ml, operation time ［85.37 ± 12.28］ min, intraoperative blood loss: ［58.08 ± 14.61］ ml), and unsatisfactory results in the other 32 (31.07%) (aged 76.91 ± 8.25 years, prostate volume: ［55.38 ± 14.73］ ml, IPSS: 22.53 ± 3.25, voiding score: 13.53 ± 3.21, storage score: 9 ［8－12］, V/S ratio: 1.36 ［1.03－1.95］, Qmax: 8 ［7－9］ ml/s, IPP: 0 ［0－5］ mm, PVR: ［129.61 ± 20.62］ ml, operation time: ［78.85 ± 10.04］ min, intraoperative blood loss: 48.76 ± 12.19 ml).

TURP yields better results in younger BPH patients, with baseline IPSS dominantly in urinary symptoms, greater IPP, lower PVR, and lower Qmax.
