Top-down holmium laser enucleation of the prostate (HoLEP) versus traditional HoLEP for the treatment of benign prostatic hyperplasia (BPH): 1-year outcomes of a randomized controlled trial.

BACKGROUND: The top-down holmium laser enucleation of the prostate (HoLEP) technique recently emerged as a safe and effective modification of traditional HoLEP. In our randomized controlled trial, we compared intraoperative and postoperative outcomes of traditional and top-down HoLEP for the treatment of benign prostatic hyperplasia (BPH) in patients with a prostate size ≥80 g. METHODS: One-hundred patients with BPH and a prostate volume ≥80 cc participated in this prospective randomized controlled trial. Outcome measures were collected and compared, including IPSS, QoL, flow rate, PVR, IIEF-15, PSA, and TRUS prostate volume changes. Perioperative complications were also recorded. All patients were followed up at 1, 3, 6, and 12 months. RESULTS: There were no significant differences in preoperative baseline characteristics between the two surgical groups. The median prostate volume for the traditional and top-down HoLEP groups was 107 and 102 cc, respectively. The operative parameters and postoperative outcomes were comparable for both cohorts. The median enucleation time for traditional HoLEP was 60 min, which was not significantly longer than that of top-down HoLEP (52 min) (p = 0.07). At 3 months follow-up, there was no statistically significant difference in transient stress urinary incontinence (SUI) in the traditional HoLEP (4.1%) versus the top-down HoLEP group (2.2%), (p = 0.61). There were no significant differences in functional and sexual outcomes between the two groups at 12 months. CONCLUSIONS: The HoLEP procedure significantly improves patients' urinary functional outcomes and has comparable postoperative outcomes regardless of the technique utilized.

Holmium laser enucleation versus bipolar resection in the management of large-volume benign prostatic hyperplasia: A randomized controlled trial.

OBJECTIVES: To compare the mid-term safety and efficacy of holmium laser enucleation of the prostate versus bipolar transurethral resection of the prostate in the management of large-volume benign prostatic hyperplasia. METHODS: From December 2016 to March 2018, patients with benign prostatic hyperplasia (≥80 cc) were randomized (block randomization, computer-generated random list) to holmium laser enucleation of the prostate (57 patients) or bipolar transurethral resection of the prostate (55 patients). Patients were excluded if they had an International Prostate Symptom Score <13, a maximum urinary flow rate >15 mL/s or presence of prostate cancer, bladder stone, urethral stricture, neurogenic bladder, or previous prostate surgery. The primary outcome was hemoglobin loss. The analysis was intention-to-treat. Postoperative findings (36 months) were compared to baseline characteristics. Univariate and logistic regression analyses were performed for risk factors predicting hemoglobin loss or operative time in all patients. RESULTS: There was no significant difference in baseline characteristics between the two groups. Holmium laser enucleation of the prostate was associated with significantly better operative time (P = 0.019), operative efficiency (P < 0.001), hemoglobin loss (P < 0.001), catheterization duration (P < 0.001) and hospital stay (P < 0.001) compared to bipolar transurethral resection of prostate. Both procedures were safe, with no significant difference in total complications (P = 0.128). Blood transfusion (P = 0.026) and capsular perforation (P = 0.239) were reported only in the bipolar transurethral resection of the prostate group. There was no significant difference in rates of urinary tract infections (P = 0.714), urethral strictures (P = 0.359), or transient stress incontinence (P = 0.717). At the last follow-up (3 years), holmium laser enucleation of the prostate was associated with significantly better International Prostate Symptom Scores, prostate-specific antigen levels and maximum urinary flow rates compared to bipolar transurethral resection of the prostate (P < 0.05). In logistic regression analyses, prostate size and bipolar transurethral resection of the prostate were associated with significantly greater hemoglobin loss, whereas prostate size, capsular perforation, and bipolar transurethral resection of the prostate were associated with significantly longer operative time. CONCLUSION: Holmium laser enucleation of the prostate and bipolar transurethral resection of the prostate are effective and safe for the management of moderate-to-severe lower urinary tract symptoms attributable to large-volume benign prostatic hyperplasia (≥80 cc). However, if both techniques are available, holmium laser enucleation of the prostate is preferred due its better efficacy and safety profile.

Holmium Laser Enucleation vs Bipolar Plasmakinetic Enucleation of a Large Volume Benign Prostatic Hyperplasia: A Randomized Controlled Trial.

Objectives: To compare safety and efficacy of bipolar plasmakinetic enucleation of prostate (BPEP) vs holmium laser enucleation of prostate (HoLEP) for management of large benign prostatic hyperplasia (BPH) (>80 g). Patients and Methods: Patients with failed medical treatment, International Prostate Symptom Score (IPSS) >13, peak urinary flow rate (Qmax)<15 mL/s and prostate size ≥80 g were enrolled in this randomized controlled trial from November 2016 to February 2018 and managed by HoLEP (Group A; 33 patients) or BPEP (Group B; 31 patients). Patients on anticoagulants (AC) were not excluded. Patients were followed up for 12 months. Perioperative data were compared between both groups using Student's-t, Mann-Whitney, Paired-t, Wilcoxon signed rank, chi-square, or Fisher-exact tests as appropriate. Results: There was no significant difference between both groups in age, rate of presentation with urinary retention, recurrent hematuria, frequency of patients on ACs/antiplatelets, prostate size, prostate specific antigen (PSA), Qmax, IPSS, quality of life (QoL), and post-void residual urine (PVRU). Operative time was significantly longer in BPEP (p = 0.003) and catheterization duration (p = 0.019). Other perioperative parameters including level of Na+ and hemoglobin, resected tissue weight, hospital stay, and complications were not significantly different between both groups. There was no need for blood transfusion in all patients. There was significant postoperative improvement in IPSS, PVRU, QoL, PSA, and Qmax in each group. However, there was no significant difference between both groups in these parameters. Conclusion: HoLEP and BPEP are comparable regarding safety and efficacy for treatment of BPH (>80 g) including patients on ACs. However, BPEP required a longer catheterization duration and operative time. ClinicalTrials.gov Identifier: NCT03998150.

Clinical versus Pathologic staging of Renal Tumors: Role of Multi-Detector CT Urography.

INTRODUCTION: Our ability to diagnose renal cell carcinoma (RCC) has increased in the past 30 years as a result of the extensive application of imaging techniques, such as ultrasonography, computed tomography, and magnetic resonance imaging. Multi-detector computed tomography (MDCT) remains the most appropriate imaging modality for the diagnosis and staging of RCC. The aim of this work was to compare the findings of MDCT with surgical pathology to determine the accuracy of delineating tumor size, localization, organ confinement, lymph node metastases, and the extent of tumor thrombus in the renal vein and inferior vena cava. METHODS: The clinical, surgical, and anatomo-pathologic records of 99 patients treated by nephrectomy (radical or partial) for solid renal tumors at Theodor Bilharz Research Institute and Nasser Institute from 2005 to 2011 were reviewed retrospectively. All cases were staged pre-operatively with abdominal MDCT (pre- and post-contrast enhancement) in addition to the routine biochemical, hematological, and radiological work-up. The tumors' histologic types were determined according to the WHO classification of renal tumors in adults in 2004, and staging was updated to the TNM 2010 system. Data were analyzed using the t-test. RESULTS: The mean age was 52 (range 21-73). Seventy-eight patients were males, and 21 patients were females (Male/Female ratio: 3.7:1). There were no significant differences in the mean tumor size between radiographic and pathologic assessments in different tumor stages. The overall incidence of lymph node invasion in surgical specimens was 76%, whereas MDCT showed a positive incidence in 68.4% of cases (false negative result in 7 cases, 7.6%). CONCLUSION: Our findings indicated that MDCT urography is an accurate method to estimate renal tumor size, lymph node, vascular and visceral metastases preoperatively. Also, preoperative staging of renal tumors with MDCT represents a valuable and accurate tool.

Low-dose bacille Calmette-Guérin for non-muscle-invasive bladder cancer: Results of a prospective study.

OBJECTIVE: To evaluate the efficacy and safety of low-dose (45 mg) intravesical bacille Calmette-Guérin (BCG) therapy in the treatment of patients with non-muscle-invasive bladder cancer (NMIBC), as intravesical BCG is the most acceptable adjuvant therapy for NMI transitional cell carcinoma of the bladder. However, in the standard regimen, undesirable effects are the main cause of treatment discontinuation. PATIENTS AND METHODS: The present study included 37 men with primary NIMBC. All patients underwent complete TURB and 2 weeks later, a 6-week course of 45 mg BCG diluted in 50 mL isotonic saline was instilled into the bladder and retained for 2 h. Patients were evaluated for BCG efficacy (recurrence with or without progression) and safety by documentation of minor and/or major side-effects. RESULTS: There were no major or severe side-effects and no treatment discontinuations. Local adverse effects occurred in 20 patients, while systemic effects, in the form of fever, occurred in six patients (16.2%). There was recurrence in 14 patients (37.8%) after 18-34 months, with disease progression (muscle invasion) in four (10.8%) after 6-18 months. The recurrence index was 0.39/100 patients/month and the mean (range) tumour-free period was 30.97 (7-36) months. CONCLUSION: Low-dose BCG intravesical therapy is an effective adjuvant treatment in NMIBC. However, this needs to be validated in future studies and in comparison with other proposed doses and/or regimens.

LAPAROSCOPIC MANAGEMENT OF DISTAL URETERIC STONE IN BILHARZIAL URETER: RESULTS OF A SINGLE CENTER PROSPECTIVE STUDY.

No doubt, Bilharzial ureters are complicated by distal stricture due to precipitation of Bilharzial ova in distal ureter. These cases are associated with poorly functioning and grossly hydronephroic kidneys that hinder endoscopic manipulation of the coexistent distal, high burden, long standing impacted stones. Thus, laparoscopic uretrolithotomy was performed in 51 bilharzial patients with distal ureteric stones 4 trocars were used. The ureter was opened directly over the stone and the stone was extracted. A double-J stent was inserted into the ureter which was closed by 4-0 polyglactin running suture. The results showed that among 51 cases 33 males and 18 females; the mean age was 40.13 years. the mean stone size was 2.73 cm. Conversion to open surgery was in only one case; the mean operative time 92.05 (range 75-120 minutes); postoperative pain score ranged from 20 to 60, the mean number of PO analgesic request was 1.72 (range 1-3); it was once in 21, twice in 23 and thrice in 7 cases. Hospital stay ranged from 2 to 5 with a mean of 2.74 days; total duration of follow up ranged from 7 to 12 with a mean of 9.68. Stone recurrence reported in 4 cases; ureteric stricture reported in 2 cases. Stone free rate was reported to be 100%.

Laparoscopic management of distal ureteric stones in a bilharzial ureter: Results of a single-centre prospective study.

OBJECTIVE: To determine the efficacy and safety of the laparoscopic management of an impacted distal ureteric stone in a bilharzial ureter, as bilharzial ureters are complicated by distal stricture caused by the precipitation of bilharzial ova in the distal ureter. These cases are associated with poorly functioning and grossly hydronephrotic kidneys that hinder the endoscopic manipulation of the coexistent distal high burden of, and long-standing, impacted stones. PATIENTS AND METHODS: We used laparoscopic ureterolithotomy, with four trocars, to manage 51 bilharzial patients (33 men and 18 women; mean age 40.13 years) with distal ureteric stones. The ureter was opened directly over the stone and the stone was extracted. A JJ stent was inserted into the ureter, which was then closed with a 4-0 polyglactin running suture. RESULTS: The mean stone size was 2.73 cm. Conversion to open surgery was required in only one patient. The mean operative duration was 92 min, the postoperative pain score was 20-60, the mean (range) number of analgesic requests after surgery was 1.72 (1-3), comprising once in 21 patients, twice in 23 and thrice in seven. The mean hospital stay was 2.74 days, and the total duration of follow-up was 7-12 months. The stone recurred in four patients and a ureteric stricture was reported in two. All patients were rendered stone-free. CONCLUSION: Laparoscopy is a safe and effective minimally invasive procedure for distal ureteric stones in a bilharzial ureter with hydronephrosis.
