Outpatient Simultaneous Treatment of Benign Prostatic Hyperplasia and Bladder Lithiasis with GreenLight™ and Holmium Laser

Outpatient 180 W XPS GreenLight™ Laser Photoselective Vaporization of the Prostate: Seven Year Experience

PURPOSE

GreenLight XPS Laser System (GL-XPS) photoselective vaporization of the prostate (PVP) is not only non-inferior to Transurethral resection of the prostate (TURP), but with shorter rates of hospital stay and length of catheterization. Scarce literature has been published about the feasibility and safety of performing GL-XPS PVP in an outpatient setting. Our aim is to report our seven-year experience with outpatient GL-XPS PVP.

METHODS

Medical charts of all patients that underwent GL-XPS PVP between 2013 and 2020 were reviewed. Patients were discharged after careful monitoring in the recovery room and the catheter was removed either at home or at a schedule hospital visit. We used the Shapiro-Wilk test to assess for normal distribution, and the evaluation of homoscedasticity was performed with the SD Test. For qualitative variables, the comparison between groups was carried using the Chi-Square test and for the quantitative variables we used the non-parametric Mann Whitney U test.

RESULTS

A total of 537 patients were treated, 517 in an outpatient basis. Median age was 68 years (IQR 62-76), median prostate volume 50 cc (IQR 40-70). 22.8% were on anticoagulants or antiplatelet therapy. Median operative time was 100 minutes (IQR 75-125), length of hospital stay 5 hours (IQR 4-6.45), mean length of catheterization 48 hours (SD 14.92). Readmission rate within 90 days of surgery was 11.7%, 58 (10.8%) for surgical-related complications. Median time for readmission was 4 days (IQR 2-24). Immediate readmission (within 10 days) was recorded in 7.6% of patients, urinary retention was the main cause. No significant differences were found trying to find perioperative predictors for readmission.

CONCLUSIONS

Our experience suggests that outpatient GL-XPS PVP could be performed safely with a predefined outpatient pathway. With a low readmission and complication rate.

A prospective evaluation of high- and low-power holmium laser settings for transurethral lithotripsy in the management of adults with large bladder calculi

PURPOSE

To prospectively investigate the efficacy and safety of high-power (100 W) vs low-power (20 W) laser settings for transurethral laser lithotripsy in the management large vesical calculi (> 4 cm).

METHODS

All patients with vesical calculi > 4 cm in the maximum dimension and scheduled for transurethral holmium laser lithotripsy were invited to participate in the study. Every alternate patient was treated with either the low- or high-power laser settings. We used a continuous irrigation resectoscope with laser bridge or a laser working element (Karl Storz) for laser lithotripsy of bladder stones. We compared the operative time, intra-operative/post-operative complications (up to 1 year), and stone-free rates between the treatment groups using IBM SPSS Statistics 24 software. Comparisons between treatment groups for continuous variables were assessed using the Welch test, while categorical variables were compared with either the Chi-square or Fisher's exact test. A p value < 0.05 was considered statistically significant.

RESULTS

Twenty patients with ten in each cohort were recruited. Preoperative data and mean bladder stone size were comparable in both groups. The duration of surgery was significantly reduced from 70.80 ± 25.28 min in low-power cohort to 40.90 ± 15.01 min in the high-power group (p = 0.005). There were no significant intra-operative complications in either group. All patients were stone-free following the procedure.

CONCLUSION

High-power laser setting of up to 100 W results in a significant reduction in duration of surgery without any increase in the complication rate for treatment of large bladder stones.

The safety and feasibility of the simultaneous use of 180-W GreenLight laser for prostate vaporization during concomitant surgery

OBJECTIVES

To explore the safety and feasibility of photo-selective vaporization of the prostate (PVP) with GreenLight XPS 180 Watt laser (GL-180- W XPS) combined with other surgical procedures.

MATERIAL AND METHODS

Data on patients in whom GL-180-W XPS was performed to relieve lower urinary tract symptoms/ benign prostatic hyperplasia (LUTS/BPH) symptoms were extracted from a multi-institutional database (2011-2016). Patients were stratified into two groups. In the first all patients who had GL-180-W XPS with a concomitant procedure during the same surgical session were included as cases while those who underwent GL-180-W XPS PVP only were included as control.

RESULTS

A total of 487 patients were included. Fifty-eight (11.9%) patients underwent concomitant procedures. Multivariable linear regression models failed to find an association between concomitant procedures and longer laser time (p = 0.4). Similarly, multivariable linear regression models failed to find an association between concomitant procedures and laser time even when the analyses were repeated and stratified into endoscopic (p = 0.6) and open/laparoscopic (p = 0.4) procedures. Multivariable logistic regression models failed to demonstrate any association between concomitant procedures and early complications (OR:1.39, CI: 0.379-2.44, p = 0.2), late complications (OR:1.84, CI:0.78-3.98; p = 0.1) and acute urinary retention (OR:1.84, CI:0.78-3.98; p = 0.1). When the analyses were repeated and the concomitant procedures stratified into endoscopic and open/laparoscopic ones, they yielded virtually the same results.

CONCLUSIONS

GL-180-W XPS PVP could be safely performed in concomitant endoscopic or open/laparoscopic surgery. These results should be taken into consideration in the counseling of the patient who might choose to undergo simultaneous procedures.

[Introduction of the photoselective vaporization of the prostate in an outpatient setting: Outcomes after the first 100 cases]

BACKGROUND AND OBJECTIVES

Our objective was to describe the progressive introduction of photoselective vaporization of the prostate (PVP) in an academic department of urology in an outpatient care setting and report our outcomes after the first 100 cases.

PATIENTS AND METHODS

Since May 2014, XPS GreenLight™ (Boston Scientific-AMS, USA) PVP in the treatment of benign prostatic hyperplasia was introduced in our department. A prospective local registry was opened to collect patients' demographics, preoperative characteristics and surgical outcomes including operative time, length of stay, catheterization time, and postoperative complications as well as functional outcomes. We also assessed limitations to the outpatient care setting.

RESULTS

Conversion to TURP was reported in 6 % for uncontrolled bleeding. Overall, 21 % patients needed more than 1-day catheterization. After 6 months of follow-up, 3 patients (prostate volume 50, 117, and 178mL) had reintervention (second PVP). Ninety days' complications were reported to be up to 6 % (3 urinary obstructions, 1 prostatitis, 1 transfusion and a severe sepsis). After 8 months, an 80 % plateau of outpatient care setting was achieved. Anesthesiologists counter-indicated outpatient care in 59 % of the cases.

CONCLUSIONS

A progressive introduction of the PVP in an outpatient care setting is associated with a low complication rate. A plateau was achieved in less than 100 procedures. The major limitation of the outpatient care setting was patients' competitive comorbidities and not disease characteristics.

Comparison of Ho:Yag laser and pneumatic lithotripsy combined with transurethral prostatectomy in high burden bladder stones with benign prostatic hyperplasia

OBJECTIVES

To compare the efficacy and reliability of Ho:YAG laser lithotripsy (HLL) and pneumatic lithotripsy (PL) in the treatment of bladder stones in patients with benign prostatic hyperplasia and stones ≥ 20 mm who were transurethrally treated in the same surgical session.

METHODS

We studied the data of patients with benign prostatic hyperplasia and ≥20 mm bladder stones who were treated with transurethral resection of the prostate and cystolithotripsy in the same session, obtained between January 2010 and February 2014 from three urology clinics. All patients underwent bipolar plasmakinetic (PK) transurethral resection of the prostate. For treatment of the bladder stone, either HLL or PL was applied. A total of 62 patients were divided into two groups: PK-PL (Group 1, n = 29) and PK-HLL (Group 2, n = 33). The data of both groups were analyzed for stone dimensions, stone fragmentation time, total operating time, hospitalization duration, prostate dimensions, success rates, and complications.

RESULTS

Group 1 included 29 patients with a mean age of 70 ± 7.6 (range, 57-85) years, whereas Group 2 included 33 patients with a mean age of 67.5 ± 10.5 (range, 45-84) years. In Group 1, five patients had mucosa injury, one patient had residual stone, and one patient had bladder perforation. In Group 2, three patients had mucosa injury, three patients had postoperative fever, and one patient had residual stone. Total operation time and stone fragmentation time were significantly lower in Group 2 (p < 0.05). The remaining analyzed data were similar (p > 0.05).

CONCLUSION

PK-HLL using a single shaft without the need for repeated access has the advantages of shorter fragmentation and operation time.

Safety and feasibility of concomitant surgery during holmium laser enucleation of the prostate (HoLEP)

PURPOSE

To determine the feasibility and outcomes associated with performing simultaneous surgical procedures during holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic hyperplasia and concomitant urologic conditions.

METHODS

A retrospective review of patients that underwent a HoLEP was performed. Patients undergoing a concomitant procedure at the time of HoLEP were selected and stratified based on complexity of the secondary procedure (simple, intermediate, and complex) and matched based on age and prostate volume to patients undergoing only a HoLEP. Baseline characteristics, preoperative, operative, and postoperative outcomes were collected.

RESULTS

A total of 372 HoLEPs were performed. Thirty-eight (10.2 %) patients underwent concomitant procedures at the time of HoLEP. Compared to the simple and intermediate secondary surgical procedures, the matched control group that underwent a HoLEP alone did not demonstrate statistically significant differences in the preoperative, operative, or postoperative outcomes. Patients with a complex secondary surgical procedure at the time of HoLEP had statistically significant differences in operative time (221 vs. 65 min, p = 0.007), estimated blood loss (92 vs. 33 mL, p = 0.012), catheter time (8.5 vs. 1 day, p = 0.041), and length of hospitalization (2 vs. 1 day, p = 0.032) compared to the control group.

CONCLUSIONS

Obstructive voiding symptoms secondary to BPH are common in older patients and may coincide with other concomitant lower urinary tract pathology that may require surgical intervention. Rather than staging surgical interventions, it appears that definitive treatment for BPH with HoLEP is safe and efficacious in those patients that also require secondary procedures.
