Evaluation of a novel technique of bladder neck and supramontanal sparing ejaculatory preserving transurethral prostatectomy.

World J Urol 2021 Jun 6. Epub 2021 Jun 6.

Department of Urology, Menoufia University Hospitals, Shebeen el kom, Egypt.

Purpose: Transurethral resection of the prostate (TURP) can achieve highly satisfying symptomatic and functional outcomes but the loss of antegrade ejaculation represents a major reason for the avoidance of surgical treatment to preserve normal ejaculation and paternity. We present a novel technique to duplicate both bladder neck sparing and supramontanal sparing with resection of apical tissues to improve voiding and antegrade ejaculation.

Methods: A prospective study done from June 2018 to June 2020 on 60 consecutive male patients with normal sexual activity diagnosed with benign prostatic enlargement. These patients were randomized into two groups; 30 patients in each group. Group 1 underwent bladder neck and supramontanal sparing ejaculatory preserving transurethral bipolar resection of prostate (ep-TUBRP) and Group 2 underwent classic transurethral bipolar resection of prostate (c-TUBRP). All patients were evaluated pre- and postoperatively (after 3 months) using IPSS, Qmax and by IIEF-5.

Results: In both groups, there were significant improvements 3 months postoperative in Qmax [7.97 mL/s to 18.47 mL/s (group A) and 7.8 to 20.7 mL/s (group B)] and in micturition symptoms according to reductions in IPSS score [24 to 7.5 (group A) and 25 to 8.5 (group B)]. IIEF-5 score improved significantly from a mean of 12.9 to 18.6 (group A) and from 11.6 to 16.4 (group B). Antegrade ejaculation reported in 80% of patients in group A and 27% in group B which was significant (p < 0.001). Postoperative period did not reveal acute urinary retention, stress urinary incontinence, or serious adverse events.

Conclusions: On short-term results, bladder neck and supramontanal ejaculation preserving transurethral bipolar resection of the prostate is superior to classic TURP in preservation of forward ejaculation with comparable efficacy in micturition parameters.

Relation of baseline prostate volume to improvement of lower urinary tract symptoms due to tamsulosin monotherapy in benign prostatic hyperplasia: An exploratory, multicenter, prospective study.

Urol Ann 2020 Jul-Sep;12(3):271-275. Epub 2020 Jul 17.

Department of Urology, Cairo University, Cairo, Egypt.

Aims: The aim of the study was to investigate the relation between baseline prostate volume (PV) and the improvement of lower urinary tract symptoms (LUTS) induced by tamsulosin monotherapy after 2-year follow-up in Egyptian benign prostatic hyperplasia (BPH) patients.

Settings And Design: This was a prospective comparative multicenter study.

Subjects And Methods: Three hundred and eighty-one BPH patients were included in the study from January 2014 to January 2017. The patients were divided according to their PV into two groups. Group A included patients with small-sized prostate (≤40 ml) and Group B included those with PV larger than 40 ml. Full evaluation was done at presentation. The patients are followed up at 6, 12, and 24 months of continued medical treatment with tamsulosin 0.4 mg once daily.

Statistical Analysis Used: Data were coded and entered using the Statistical Package for the Social Sciences version 24. Data were summarized using mean and standard deviation in quantitative data. Comparisons between quantitative variables were done using unpaired -test or the nonparametric Mann-Whitney test. A comparison between paired measurements in the same person was done using paired -test (Chan, 2003). P < 0.05 was considered as statistically significant.

Results: The mean age was 60.1 ± 7.2 years. The mean value of the International Prostate Symptom Score (IPSS) was recorded for the 381 patients at presentation. In Group A, the mean value of IPSS was 20.44 ± 3.18, whereas in Group B, the mean value of IPSS was 21.23 ± 3.5. There was a significant improvement in symptoms (Q-IPSS) in both groups, but we found that this improvement was significantly better in Group A ( = 0.017).

Conclusions: PV is an important prognostic factor affecting the improvement of the LUTS by α1-blocker monotherapy. Tamsulosin monotherapy may not be enough for large prostate (>40 mg) to maintain adequate symptom relief, and it is better to start with other medical options such as combined therapy or early nonmedical therapy. Starting α1-blocker monotherapy in smaller prostates may be of benefit in symptomatic patients without considering watchful waiting.

The safety of ureteral stenting with the use of potassium citrate for management of renal uric acid stones.

Urol Ann 2020 Jan-Mar;12(1):37-41. Epub 2019 Nov 7.

Department of Urology, Menoufia University, Al Minufiyah, Egypt.

Objectives: The objective is to evaluate the relative risks of ureteric stents application while managing uric acid stones with potassium citrate in terms of stone encrustations and urinary tract infection (UTI).

Patients And Methods: We prospectively enrolled patients with renal uric acid stones who received K citrate from 2013 to 2018. Patient's demographics were collected. All patients were evaluated using noncontrast computed tomography (CT) scan to measure the stone size and density. JJ ureteric stent was inserted prior to the initiation of treatment. At follow-up, all patients underwent urine analysis for pH and to detect UTI. CT was repeated at 1 month and those patients who showed incomplete stone resolution underwent another course of treatment for another month. CT was repeated prior to stent removal. The presence of encrustations was inspected and collected.

Results: We collected 59 patients with a median age of 36 years (18-73) and median stone burden of 26 mm (15-50). The median stone density was 310 HU (175-498). Twenty-one patients (35.6%) received K citrate treatment for 1-month, while the remaining patients had 2 months treatment. Sixteen patients (27.1%) had a complete stone dissolution, 41 patients (69.5%) had more than 50% decrease of stone burden while only 2 patients (3.4%) had stones with poor dissolution. Four patients (6.8%) experienced UTI while 2 patients (3.4%) had visible JJ encrustations. Most of these complications occurred when the treatment was offered for the 2 month.

Conclusion: Short-term use of ureteral stents is safe during the management of uric acid stones with K citrate.

Ciprofloxacin infusion versus third generation cephalosporin as a surgical prophylaxis for percutaneous nephrolithotomy: a randomized study.

Cent European J Urol 2019 14;72(1):57-61. Epub 2019 Jan 14.

Menoufia University, Faculty of Medicine, Department of Urology, Shbeen el Kom, Egypt.

Introduction: Percutaneous nephrolithotomy (PCNL) is considered a clean-contaminated surgical procedure. The American Urological Association has recommended different preoperative antimicrobial prophylaxis for various urological procedures to prevent surgical site infections, postoperative fever, and possible sepsis. The European Association of Urology (EAU) antibiotic guidelines endorse giving either a second or third-generation cephalosporin, trimethoprim-sulfamethoxazole, fluoroquinolone or aminopenicillin with a β-lactamase inhibitor. The aim of the present study is to prospectively compare two different protocols of antibiotic prophylaxis in PCNL.

Material And Methods: Successfully consented patients with sterile urine preoperatively who were awaiting percutaneous nephrolithotomy were randomized into two groups. The first group (n = 41) was given a single dose of 200 mg ciprofloxacin infusion, while group two (n = 43) was given 2 mg of cefotaxime divided into 2 doses; during induction of anesthesia and 12 hours later. The occurrence of perioperative infection-related events would be compared in both groups.

Results: Both groups had similar age, sex, Body Mass Index, and stone composition. No statistical difference was found regarding stone size, stone culture, irrigation fluid volume, operative time and urine pelvis culture result in both groups (Table 2). Two patients (5%) developed postoperative fever in the 1 group compared to 12 patients (28%) in the second group (p = 0.02).

Conclusions: A prophylactic regimen consisting of a single dose ciprofloxacin infusion during induction of surgery showed a higher efficacy as a preoperative antibacterial preparation, compared to cefotaxime, in protection against postoperative fever in patients undergoing PCNL.

Microscopic subinguinal varicocelectomy in 100 consecutive cases: Spermatic cord vascular anatomy, recurrence and hydrocele outcome analysis.

Arab J Urol 2018 Mar 1;16(1):181-187. Epub 2018 Feb 1.

Department of Urology, Menoufia University, Menofia Governorate, Egypt.

Objective: To evaluate the detailed vascular anatomy of the spermatic cord during subinguinal microscopic varicocelectomy and to assess the outcome of the cases with regard to varicocele recurrence and hydrocele formation.

Patients And Methods: In all, 100 varicocele cases including 74 left-sided and 26 bilateral, comprising 126 spermatic cord units with clinically palpable varicoceles underwent microscopic subinguinal varicocelectomy. Detailed description of vascular anatomy of the spermatic cords was reported. The number of spermatic, cremasteric, and inguinal veins was recorded. A record of testicular arteries and lymphatics was noted. Testicular delivery was done in all the cases and assessment of the gubernacular veins was reported. The patients underwent clinical evaluation, as well as scrotal Doppler ultrasonography, to detect varicocele recurrence and hydrocele formation. The mean (range) postoperative evaluation period was 6 (3-12) months.

Results: The mean number of spermatic veins was 14 on both sides. The mean number of spermatic arteries on both sides was 1.3. For lymphatics, the mean number was around three on both sides. The gubernacular veins were noted in 75% of the cases on the left side (mean number of 1.2) and in 85% on the right-side, (mean number of 1). The mean number of cremasteric veins on the left and right sides was 1.4 and 1.2, respectively. Finally, inguinal floor vessels were noted in 9% on the left-side and were not seen in the right-side cases. The incidence of varicocele recurrence was 2% and for hydrocele that was not clinically significant was 0.07%.

Conclusion: Microscopic subinguinal varicocelectomy accurately evaluated the detailed vascular anatomy of the spermatic cord, achieving excellent surgical outcome with minimal varicocele recurrence and hydrocele formation. Microscopic subinguinal varicocelectomy should be the 'gold standard' for varicocelectomy.

Prognostic Factors for Hormone Sensitive Metastatic Prostate Cancer: Impact of Disease Volume

Asian Pac J Cancer Prev 2018 Apr 27;19(4):1113-1118. Epub 2018 Apr 27.

Department of Clinical Oncology and Nuclear Medicine,Faculty of Medicine, Menoufia University, Egypt. Email:

Background and Aim: The optimal management of metastatic hormone-sensitive prostate cancer has been controversial in recent years with introduction of upfront chemohormonal treatment based on results of several Western studies. This changing landscape has renewed interest in the concept “disease volume”, the focus of the present study is the Egyptian patients. Methods: Patients with hormone sensitive metastatic prostate cancer presenting at Menoufia University Hospital, Egypt, during the period from June 2013 to May 2016, were enrolled. All received hormonal treatment. Radiologic images were evaluated and patients were stratified according to their disease volume into high or low, other clinical and pathological data that could affect survival also being collected and analyzed. Results: A total of 128 patients were included, with a median age of 70 years (53.9% ≥70). About 46% had co-morbidities, 62% having high volume disease. During the median follow up period of 28 months about half of the patients progressed and one third received chemotherapy. On univariate analysis, disease volume, performance status (PS), prostate specific antigen level (PSA) and presence of pain at presentation were identified as factors influencing overall survival. Multivariate analysis revealed the independent predictor factors for survival to be PS, PSA and disease volume. The median overall survival with 27 months was high volume versus 49 with low volume disease (hazard ratio 2.1; 95% CI 1.2 - 4.4; P=0.02). Median progression free survival was 19 months in the high volume, as compared with 48 months in the low volume disease patients (hazard ratio, 2.44; 95% CI, 1.42 – 7.4; P=0.009). Conclusions: Disease volume is a reliable predictor of survival which should be incorporated with other important factors as; patient performance status and comorbidities in treatment decision-making.

Management of equivocal (early) Fournier's gangrene.

Ther Adv Urol 2016 Oct 28;8(5):297-301. Epub 2016 Jun 28.

Urology Department, Farwaniya Hospital, Kuwait.

Background: Fournier's gangrene (FG) is an acute progressive necrotizing fasciitis of the genital area and perineum with possible extension to the abdominal wall. Surgical debridement is the gold standard management modality of established patients. Equivocal (early) FG represents a challenge in diagnosis. The objective of this study was to compare conservative management and early exploration in cases of equivocal (early) FG.

Methods: This was an observational study where data of all patients diagnosed as early FG in our departments over 4 years (2011-2015) were enrolled. Patients were divided into two groups: group 1 with conservative treatment, and group 2 managed with urgent exploration with longitudinal hemiscrotal incision starting from external inguinal ring. All patients' demographics, vital signs, laboratory finding and clinical findings were reported.

Results: A total of 28 patients were enrolled in the study. Group 1 was managed with conservative treatment (17 patients) and group 2 underwent urgent exploration (11 patients). Overall, four patients (23.5%) out of 17 patients of group 1 showed a good response to conservative management without any surgical debridement. A total of 13 patients (76.5%) developed gangrenous discoloration and needed surgical debridement later. In group 2, four patients (36.4%) underwent scrotal exploration and release incision only without debridement and showed an excellent clinical outcome. A total of four patients (36.4%) underwent debridement with excision of doubtful deep subcutaneous and fascial tissues. The remaining three patients (27.2%) underwent debridement of necrotic fascia. The hospital stay was significantly shorter in group 2 patients than group 1 (7.5 ± 3.75 13.4 ± 5.19 days < 0.05). The mean number of debridement sessions was 3.74 ± 0.69 in group 1 1.82 ± 0.34 in group 2.

Conclusions: Early exploration and debridement in equivocal (early) FG has a better clinical outcome with reduced hospital stay and number of debridement sessions than conservative treatment with delayed debridement.
