Risk factors for delayed hematuria following photoselective vaporization of the prostate

Predictive Value of Voiding Efficiency After Active Void Trial in Men Undergoing BPH Surgery

OBJECTIVES

To determine the predictive value of voiding efficiency on acute urinary retention after discharge from BPH surgery.

MATERIALS AND METHODS

We performed a prospective observational cohort study of three surgeons' practices from 2019 to present. All men included underwent trial of void on post-operative day one after transurethral resection of prostate or Holmium enucleation of prostate . Active filling void trials were performed on all patients and voiding efficiency (percent of bladder volume emptied) was calculated. Multivariable logistic regression was performed to determine predictors of developing acute urinary retention.

RESULTS

During the study period, 188 men met inclusion criteria. 110 (59%) men underwent Holmium enucleation of prostate , and 78 (41%) underwent transurethral resection of prostate. The median age of our cohort was 70 (IQR 65-75). The median prostate size was 100g (IQR 61-138g). Nineteen patients (10%) returned after discharge with acute urinary retention requiring catheterization. On post-operative day one, the median voiding efficiency was 75% (IQR 55%-94%). On multivariable analysis, patients with a voiding efficiency less than 50% were 3.8 times more likely (95% confidence interval 1.1-12.8) to develop subsequent retention compared to a voiding efficiency of greater than 75%. Increasing pre-operative prostate size was associated with lower risk of urinary retention after discharge (aOR 0.8, 95%CI 0.6-0.9).

CONCLUSIONS

Voiding efficiency after an active void trial helps stratify risk of urinary retention in patients undergoing benign prostate surgery. High-risk patients include those with voiding efficiencies less than 50% and smaller pre-operative prostate sizes (<80g).

Risk Factors of Emergency Room Visits for Bleeding Complications Following Transurethral Procedures in the Treatment of Benign Prostatic Hyperplasia: A Retrospective Cohort Study

Purpose

Transurethral procedures, including transurethral resection of the prostate (TURP) and laser prostatectomy, are often linked to emergency room (ER) visits for postoperative bleeding. Although some studies have been conducted, the risk factors associated with these ER visits are not completely understood. This retrospective cohort study identified potential risk factors associated with ER visits for postoperative bleeding.

Patients and Methods

Preoperative assessment data and operational and postoperational parameters recorded at Chang Gung Memorial Hospital, Taiwan between December 2015 and January 2017 for patients who underwent elective transurethral procedures were analyzed to identify potential risk factors. The primary endpoint was ER visits for gross hematuria within three months following operation, and the secondary endpoint was ER visits for blood clot-induced urinary retention (clot retention) within three months following operation.

Results

A total of 665 patients who underwent elective transurethral procedures were enrolled. The transurethral procedures included monopolar transurethral resection of the prostate (M-TURP), bipolar TURP (B-TURP), greenlight photoselective vaporization of the prostate (PVP), thulium laser enucleation of the prostate (ThuLEP) and thulium laser transurethral vaporesection of the prostate (ThuVARP). Regarding ER visits for clot retention within three months, multivariable logistic regression revealed significantly lower rates of clot retention in patients who received B-TURP than in those who underwent ThuVARP (AOR, 0.18; 95% confidence interval [CI], 0.04–0.82, p = 0.027). Moreover, significantly higher clot retention was observed in patients who underwent two or more rounds of manual irrigation (AOR, 9.51; 95% CI, 1.66–54.43, p = 0.011).

Conclusion

Multiple manual irrigations shortly after operation can be considered a novel predictor of postoperative clot retention-related ER visits. Among the transurethral procedures, ThuVARP was associated with a higher risk of clot retention-related ER visits than was B-TURP.

[Evaluation of postoperative symptoms after Greenlight™ photovaporization of the prostate through a dedicated questionnaire]

AIMS

To evaluate postoperative symptoms after Greenlight™ photovaporisation of the prostate (PVP), through a dedicated questionnaire.

METHODS

A retrospective study has been conducted between 2008 and 2014. The questionnaire had 5 sections about pain while voiding, hematuria, urgency, incontinence and urinary stream, and was filled at one-month postoperative. The main outcome criterion was pain while voiding. Descriptive statistical analyses were done to identify predictive factors for pain while voiding.

RESULTS

Out of 169 patients, 22% had no pain while voiding, 37% had moderate pain, 30% acceptable pain and 11% intense pain. Patients with pain were significantly older, (P=0.012), had more urgency (P=0.01) and more often hematuria (P=0.0001). Only 7% of patients had no symptoms of urgency, and urgency was painful or bothering in 57% of cases. Hematuria was frequent, with clots in 21% of cases. Ninety three percent felt improvement of urinary stream.

CONCLUSIONS

Systematic evaluation of symptoms through a dedicated questionnaire one month after PVP has shown that 41% of patients felt pain while voiding, 57% had urgency and 39% significant hematuria. These results should encourage a more accurate patient information and further studies to better understand postoperative healing after PVP.
