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.

Comparing non contrast computerized tomography criteria versus dual X-ray absorptiometry as predictors of radio-opaque upper urinary tract stone fragmentation after electromagnetic shockwave lithotripsy.

The objective of this study was to assess the value of dual X-ray absorptiometry (DXA) in comparison to non contrast computed tomography (NCCT) density as possible predictors of upper urinary tract stone disintegration by shock wave lithotripsy (SWL). This study included 100 consecutive patients, with solitary renal stone 0.5-2 cm or upper ureteral stone up to 1 cm. DXA to calculate stone mineral density (SMD) and stone mineral content (SMC) was done. NCCT was performed to measure Hounsfield units (HU). SWL was performed with an electromagnetic lithotripsy, plain X-ray documented disintegration after SWL. Successful treatment was defined as stone free or complete fragmentation after 1 or 2 sessions of SWL. The impact of patients age, sex, body mass index, stone laterality, location, volume, length, mean SMC and SMD, HU and Hounsfield density (HD), skin to stone distance (SSD) and number of shock waves were evaluated by univariate and multivariate analysis. Only 76 patients were available for follow-up. Success of disintegration was observed in 50 out of 76 patients (65.8 %). On multivariate analysis, SMC and number of shock wave were the significant independent factors affecting SWL outcome (p = 0.04 and p = 0.000, respectively). SMC as detected by DXA is a significant predictor of success of stone disintegration by SWL. SMC measured by DXA is more accurate than HU measured by CT. Patients with high stone mineral content (SMC greater than 0.65 g) should be directly offered another treatment option.

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.
