Efficacy and safety of TURP, HoLEP, and PVP in the management of OAB symptoms complicating BPH in patients with moderately enlarged prostates: A comparative study

INTRODUCTION

We aimed to compare the effectiveness and safety of transurethral resection of the prostate (TURP), holmium laser enucleation of the prostate (HoLEP), and photoselective vaporization of the prostate (PVP) in management of storage and overactive bladder (OAB) symptoms complicating benign prostatic hyperplasia (BPH) in patients with moderately enlarged prostates.

METHODS

The charts of patients with moderately enlarged prostates and BPH complicated by storage and OAB symptoms who were treated by TURP, HoLEP, and PVP at University of Cincinnati hospitals between March 2012 and December 2020 were retrospectively reviewed and analyzed for changes in storage and OAB symptomatology, International Prostate Symptom Score (IPSS), peak flow rates (Qmax), presence of detrusor overactivity (DO), and postvoid residual (PVR) from baseline to up to six months postoperatively.

RESULTS

A total of 204 patients with moderately enlarged prostates and BPH complicated by storage and OAB symptoms were divided into three groups: group 1 (patients who underwent TURP, 89 patients), group 2 (those who underwent HoLEP, 64 patients), and group 3 (those who underwent PVP, 51 patients). TURP, HoLEP, and PVP were associated with significant improvement in urodynamics study (UDS) parameters, patient storage and OAB symptomatology, and IPSS from preoperatively to both three and six months postoperatively in BPH patients with moderately enlarged prostates, with relatively low procedure complication rate and postoperative need for either anticholinergic or procedure.

CONCLUSIONS

TURP, HoLEP, and PVP are effective and reliable surgical procedures that can be relied upon for BPH patients with moderately enlarged prostates and storage or OAB symptoms, with comparable efficacy and relatively low procedure complication rate and postoperative need for anticholinergic or additional procedure.

Is Holmium Laser Enucleation of Prostate equally effective in management of benign prostatic hyperplasia patients with either voiding or storage lower urinary tract symptoms? A comparative study

OBJECTIVE

To evaluate and compare the effectiveness and safety of holmium laser enucleation of prostate (HoLEP) in relieving either voiding or storage lower urinary tract symptoms (LUTS) in benign prostatic hyperplasia (BPH) patients.

MATERIALS AND METHODS

The charts of patients with BPH who underwent HoLEP for either predominant voiding or predominant storage LUTS at University of Cincinnati hospitals in the period between February 2015 and December 2020 were retrospectively reviewed and analyzed for changes in voiding symptomatology, storage symptomatology, hematuria, International Prostate Symptom Score (IPSS), peak flow rates (Qmax), presence of detrusor overactivity (DO), and post-voiding residual urine (PVR) from baseline to up to 6 months postoperatively.

RESULTS

A total of 132 patients were included in the analysis. Patients were divided into two groups: Group 1 included BPH patients with predominant voiding LUTS (68 Patients) while group 2 involved those with predominant storage LUTS (64 Patients). HoLEP was equally effective in management of both groups with significant improvement in urodynamics study (UDS) parameters, patient voiding and storage symptomatology, and IPSS from preoperatively to up to 6 months postoperatively with relatively low procedure complication rate and postoperative need for medication or procedure.

CONCLUSIONS

HoLEP is a safe, effective, and reliable minimally invasive surgical modality that can be relied on for BPH patients with either predominant voiding or predominant storage symptoms with relatively low procedure complicat.

Primary versus deferred ureteroscopy for management of calculus anuria: a prospective randomized study

Introduction

Obstructive anuria can be managed by primary ureteroscopy (URS) or deferred URS after initial ureteral stenting. We want to compare the primary URS and deferred URS in the management of calculus anuria regarding the feasibility and clinical outcome.

Material and methods

Between January 2012 and December 2014, 150 patients with anuria due to ureteral calculi were prospectively randomized according to the timing of ureteroscopic intervention into two groups; deferred URS group (69 patients who were treated initially by ureteral stenting) and primary URS group (81 patients who were treated by emergency URS). Follow-up was at least 6 months postoperatively.

Results

Complete stone clearance was 87 % and 75.3% for deferred and primary URS groups, respectively (p = 0.097). Renal function normalized in 94.2% of deferred URS vs. 97.5% of primary URS (p = 0.414). Deferred URS group had a 2.9 % overall complication rate in comparison to 9.9 % for the primary URS group (p = 0.109). Ureteral perforation/pyelonephritis was noted in 6.2% of the primary URS group only (p = 0.043). The median number of maneuvers required until stone clearance was one (range 1–5) for primary URS vs. two (range 2–3) for deferred URS (p <0.001). The cost of primary URS was significantly less (p <0.001). On a multivariate analysis, lower ureteral calculi (OR 13.03, 95% CI 4.07– 41.7, p <0.001) and deferred URS (OR 2.84, 95% CI 1.07–7.49, p = 0.035) were independent predictors for an eventless and successful URS.

Conclusions

Primary URS for calculus anuria is feasible and cost-effective. It has a short hospital stay, but is still technically demanding. The perioperative complications are comparable to URS in normouric patients.

Primary versus secondary ureteroscopy for pediatric ureteral stones

OBJECTIVE

To evaluate the outcome of primary versus secondary ureteroscopy for pediatric ureteral stones.

PATIENTS AND METHODS

A retrospective chart review study that included 66 children aged less than 12 years, who were subdivided into two groups: Group A, which included 42 children who had undergone primary ureteroscopy without pre-stenting; and Group B, which included 24 children who had undergone ureteroscopy after ureteric stenting. Kidneys, ureters and bladder radiographs were done on the first postoperative day to assess the degree of stone clearance and stent position.

RESULTS

Age, gender, stone location and stone size were not significantly different between both groups. In Group A, 31 (73.8%) children required ureteric dilation, 13 (31%) had a tight ureter that failed to respond to dilation, 25 (59.5%) displayed complete stone clearance, and of these, 13 (52%) needed postoperative stenting. One child experienced ureteric injury during stone disintegration and was stented for two weeks. Children in Group B experienced a 95.8% complete stone clearance rate, with no ureteric injury reported; postoperative stenting was performed in three (12.5%) children..

CONCLUSION

Secondary ureteroscopy is preferable over primary ureteroscopy in pediatric populations because of a significantly lower need for ureteric dilation, shorter procedure time and better stone clearance rate..

Management of calculus anuria in children: experience of 54 cases

OBJECTIVE

To evaluate the outcome of different treatment plans for calculus anuria in children.

PATIENTS AND METHODS

Patients were subdivided into three groups, A, B and C. Group A included patients who were critically ill, had serum creatinine> or =3.5mg/dl, blood urea> or =100mg/dl, serum potassium> or =7meq/l and/or blood pH< or =7.1; and they were treated initially by peritoneal dialysis. Patients in groups B and C were stable with serum creatinine<3.5mg/dl, blood urea<100mg/dl, serum potassium level<7meq/l and blood pH>7.1. In group B, the obstructing stone could not be localized, and they were treated either by percutaneous nephrostomy or JJ stent. In group C, stone level was confidently determined and patients were treated by open surgery.

RESULTS

Fifty-four patients were included. All patients regained normal serum creatinine levels within 72-120h. Overall complication rate in groups A and C was 26% and 13%, respectively. In group B, overall complication rate was 66% for percutaneous nephrostomy and 50% for internal stent.

CONCLUSIONS

Urinary diversion in children is associated with a high complication rate while dialysis is highly effective in children. Formal surgery in compensated children is associated with a low complication rate with good outcome and early recovery.

New concept in urethral advancement for anterior hypospadias

OBJECTIVE

We report on our experience with urethral mobilization and advancement as a treatment for anterior hypospadias.

PATIENTS AND METHODS

From January 2004 to March 2007, 55 out of 160 children with anterior hypospadias were managed by urethral mobilization and advancement; 46 had a mean follow-up period of 25 months (range 6-38) and are the subjects of this report. Their ages ranged from 2.5 to 12 years with mean age 4.5 years. The dissection began proximally in the avascular plane above the tunica albuginea covering each corpus cavernosum medially until reaching beneath the corpus spongiosum up to the hypospadiac meatus. Tension-free urethral anastomosis was achieved. The ventral glans was incised deeply at the interballanitic groove. The two glans wings and ventral glanular mucosal flaps were mobilized laterally. Interrupted sutures were placed through the tunica albuginea of corpus spongiosum to the corpora cavernosa. The mobilized urethra was wrapped by dartos fascia. The urethral stent was removed 24h postoperatively.

RESULTS

Three-fold urethral mobilization was sufficient to achieve tension-free urethral anastomosis. A slit-like orthotopic meatus, with conically shaped glans and straight penis, was achieved in all but one subcoronal case with mid-glans meatal retraction during our early experience. Postoperative urethral fistula was not recorded in any patient. Satisfactory urinary stream for parents and child was reported in 42/46. Peak flow rate was within normal range (upper 50% percentile) in all.

CONCLUSION

Urethral mobilization should begin proximally. Three-fold penile urethral mobilization, deep interballanitic incision and wide dissection of the glans can provide a slit-like orthotopic meatus with conical glans and straight penis in cases of anterior hypospadias without hypoplastic distal urethra and persistent ventral curvature after penile skin degloving, regardless of the presence of unhealthy, narrow urethral plate, shallow glanular groove, and flat or small glans.
