Combined prostatic urethral lift and remodeling of the prostate and bladder neck: a modified transurethral approach in the treatment of symptomatic lower urinary tract obstruction

Urinary and sexual function changes in benign prostatic hyperplasia patients before and after transurethral columnar balloon dilatation of the prostate

BACKGROUND

Transurethral columnar balloon dilatation of the prostate (TUCBDP) is a new surgical treatment, but its efficacy remains controversial because of limited clinical application.

AIM

To investigate the clinical effect of TUCBDP for benign prostatic hyperplasia (BPH).

METHODS

Overall, 140 patients with BPH who underwent surgical treatment were included in the study. A random number table was used to divide the participants into study and control groups (n = 70 per group). The study group underwent TUCBDP. The prostate resection surgical time, intraoperative blood loss, bladder irrigation time, catheter indwelling time, length of hospital stay, International Prostate Symptom Score (IPSS), maximum urine flow rate (Qmax), residual urine volume (RUV), changes in the International Erectile Function Score (IIEF-5) score, serum prostate-specific antigen (PSA), quality of life (QOL) score, and surgical complications were compared in both groups.

RESULTS

The operation time, intraoperative blood loss volume, bladder flushing time, urinary catheter indwelling time, and length of hospital stay were significantly lower in the study group than in the control group (P < 0.05). There were no significant differences in the IPSS, Qmax, and RUV measurements between the study and control groups (P > 0.05). However, at 3 mo post-surgery, the IPSS and RUV measurements were both lower (P < 0.05) and Qmax values were higher (P < 0.05) compared to the pre-surgery results in both groups. The IIEF-5 scores before and 3 mo after surgery were not significantly different between the study and control groups (P > 0.05). At 1 mo after surgery, the IIEF-5 score was higher in the study group than in the control group (P < 0.05). The serum PSA levels and QOL scores before treatment and at 1 and 3 mo after treatment were not significantly different between the study and control groups (P > 0.05). However, lower serum PSA levels and QOL scores were observed after 1 and 3 mo of treatment compared to pre-treatment levels in the study group (P < 0.05). The surgical complication rate of the study group (4.29%) was lower than that of the control group (12.86%; P < 0.05).

CONCLUSION

TUCBDP for BPH and transurethral resection of the prostate can achieve better results, but the former method is associated with less surgical trauma.

[Sophisticated surgical management of distinctive patients with benign prostatic hyperplasia (BPH)]

Herein we describe four clinical scenarios. For the standard patient (prostate volume 30-80 ml, life expectancy >10 years) transurethral resection of the prostate (TURP) remains the standard of care, while endoscopic enucleation is a valuable alternative. Patients with a relevant middle lobe profit most from TURP, endourological enucleation procedures, or laser vaporization. In the case of the absence or a moderate-sized middle lobe and the absence of severe bladder outlet obstruction (BOO), minimally invasive procedures such as Rezūm®, UroLift® or prostate artery embolization (PAE) can be offered. Patients have to be informed that long-term data on this specific indication are lacking. Particularly younger men requiring BPH surgery are interested in preserving ejaculatory function. In the presence of severe BOO, ejaculatory-protective TURP or endoscopic enucleation by preserving the pericollicular region or aquablation are the methods of choice providing an antegrade ejaculation in 60-90% of cases. Rezūm®, AquaBeam®, and UroLift® enable preservation of ejaculation in almost 100%; data on PAE with this respect are more controversial. For patients with a small prostate and significant post void residual, a thorough preoperative work-up, including urodynamics and bladder/detrusor wall thickness measurement, is of great importance. Desobstructive surgery provides satisfactory short- and midterm outcome, yet the long-term outcome is disappointing and remains to be determined in greater detail. The broad spectrum of therapeutic options enables today an individualized minimally invasive or surgical management of BPH considering patient wishes, anatomical factors or urodynamic factors. The time of a "one therapy fits all" strategy is definitely history.
