Article Synopsis
- Non-obstructive azoospermia (NOA) is a prevalent and complex issue with varied treatment options and no definitive guidelines, leading to differing management practices internationally.
- A comprehensive survey with 336 responses from specialists in 49 countries explored current medical and surgical strategies for NOA, analyzing results against existing guidelines and offering expert recommendations.
- Key findings included diverse approaches to hormonal therapy, significant variation in sperm retrieval success rates, and differing protocols around varicocele repair and follicle-stimulating hormone cutoff levels for sperm retrieval.
Article Synopsis
- * Conducted from July to September 2022, a questionnaire gathered responses from 367 doctors in 49 countries, focusing on how they diagnose NOA through methods like hormone tests and genetic analyses.
- * The survey identified that while many practices align with guidelines, significant differences in approaches were found, underscoring the need for standardized, evidence-based international guidelines for NOA evaluation.
Article Synopsis
- The meta-analysis investigates the effects of varicocele repair on semen parameters in infertile males, combining data from diverse studies without language restrictions.
- A total of 351 studies were analyzed, revealing significant improvements in several semen parameters post-repair, including semen volume, sperm concentration, total sperm count, motility, and morphology, while sperm vitality showed no improvement.
- This research is the largest of its kind and highlights the benefits of varicocele repair for male infertility, contributing valuable insights for clinical practice.
Introduction: To evaluate the efficacy and safety of intraprostatic injections of onabotulinumtoxinA (onaBoNT-A) to treat refractory chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).
Materials And Methods: Prospective two-group controlled study. Treatment group included adult men with refractory category-III nonbacterial CP/CPPS who underwent transurethral intraprostatic injections of onaBoNT-A (200 U).
Background: Renal cell carcinoma (RCC) is a seventh ranked malignancy with poor prognosis. RCC is lethal at metastatic stage as it does not respond to conventional systemic treatments, and there is an urgent need to find out promising novel biomarkers for effective treatment. The goal of this study was to evaluate the biomarkers that can be potential therapeutic target and predict effective inhibitors to treat the metastatic stage of RCC.

View Article and Find Full Text PDFThe S100A8 and epidermal growth factor receptor (EGFR) proteins are proto-oncogenes that are strongly expressed in a number of cancer types. EGFR promotes cellular proliferation, differentiation, migration and survival by activating molecular pathways. Involvement of proinflammatory S100A8 in tumor cell differentiation and progression is largely unclear and not studied in kidney cancer (KC).
View Article and Find Full Text PDFObjective: To examine the hypotheses that clinical varicoceles affect baseline serum total testosterone levels (T) and varicocelectomy improves T.
Materials And Methods: This prospective, nonrandomized, controlled study involved 4 groups of adult men. Varicocele-infertile treatment group (VIT) included 66 men who underwent varicocelectomy.
Background/aim: The proinflammatory protein S100A8, which is expressed in myeloid cells under physiological conditions, is strongly expressed in human cancer tissues. Its role in tumor cell differentiation and tumor progression is largely unclear and virtually unstudied in kidney cancer. In the present study, we investigated whether S100A8 could be a potential anticancer drug target and therapeutic biomarker for kidney cancer, and the underlying molecular mechanisms by exploiting its interaction profile with drugs.
View Article and Find Full Text PDFBackground And Objectives: The Gleason grading of prostate carcinoma (PCa) in needle core biopsies is a major determinant used in management planning. The objective of this study was to evaluate the concordance between general pathologists Gleason grading and that of a urologic pathologist in our community.
Design And Setting: Retrospective review conducted at three tertiary care hospitals in Jeddah and Riyadh for all prostatic biopsies with carcinoma from January 2002 to January 2011.
Objective: We evaluated the safety and efficacy of photoselective vaporization of the prostate (PVP) using GreenLight 120-W lithium triborate (LBO) laser to treat symptomatic small-to-medium sized benign prostatic hyperplasia (BPH).
Methods: This prospective non-controlled observational study included symptomatic BPH men ≥50 years with international prostate symptom score (IPSS) ≥14, prostate volume (PV) ≤80 cc and maximum flow rate (Q-max) ≤15 mL/s. PVP was performed using the GreenLight 120-W LBO laser machine.
Background: Randomized controlled trials (RCTs) addressing varicocele treatment are scarce and have conflicting outcomes.
Objective: To determine whether varicocele treatment is superior or inferior to no treatment in male infertility from an evidence-based perspective.
Design, Setting, And Participants: A prospective, nonmasked, parallel-group RCT with a one-to-one concealed-to-random allocation was conducted at the authors' institution from February 2006 to October 2009.
Objective: To determine the clinicopathologic patterns of prostatic diseases in Saudi patients, with special emphasis on prostate cancer (PCa).
Methods: The records of patients who underwent histopathological examinations of their prostatic specimens in King Abdulaziz University Medical City and King Faisal Specialist Hospital, Jeddah, Kingdom of Saudi Arabia, between June 2003 and June 2008 were reviewed retrospectively. The age, indications for biopsy, histological diagnosis, and Gleason grading of cancer patients, were studied.
Objective: To demonstrate the efficacy of shock wave lithotripsy (SWL) in the primary treatment of 1647 patients with renal calculi using a Dornier Doli U/50 lithotripter.
Methods: One thousand and six hundred forty-seven patients underwent SWL as day-cases at King Abdulaziz University Hospital in Jeddah, Saudi Arabia between October 2001 and July 2007, using intravenous sedation (Pethidine 1mg/kg and Midazolam 5-10mg) for analgesia in 85.5% of the patients.
