Abstract Objectives: Testicular torsion is the most common surgical cause of an acute scrotum. Manuel detorsion renewed attention as a practical initial treatment, particularly in the COVID-19 pandemic. This study aims to systematically review and meta-analyze the current literature to determine whether manual detorsion offers a viable alternative to immediate surgery in improving testicular salvage rates. Methods: A systematic review and meta-analysis were conducted in accordance with PRISMA guidelines and registered with PROSPERO (CRD420251039489). Studies including ≥30 male patients comparing manual detorsion and surgical exploration were included. Searches were performed in PubMed/MEDLINE, Scopus, TR Index, and… More >

Abstract Background: Tuberculosis (TB) is a globally prevalent infectious disease, including in Taiwan. Prostatic TB is a rare manifestation of genitourinary tuberculosis (GU-TB), which is the third most common extrapulmonary form of the disease. However, due to its insidious onset and non-specific symptoms, prostatic TB is often diagnosed late. Case Description: We report a case of a 72-year-old male patient who presented with lower urinary tract symptoms (LUTS) and painful scrotal swelling. Following transurethral resection of the prostate (TURP), histopathological examination revealed prostatic TB. The patient subsequently had abdominal cramping and diarrhea. A colonoscopy detected an ulcer-like More >

Abstract Mammalian fertilization involves the migration of spermatozoa through the female reproductive system. Early embryonic development is a consequence of several steps and signaling pathways being activated, as well as biochemical and morphological modifications of spermatozoa that enable them to penetrate the membrane of mature oocytes.
There are some crucial steps known to clearly explain the process of fertilization, starting with hyperactivation of spermatozoa, mutual recognition, and binding of gametes mediated by receptors located on the surface membranes of both gametes. The final step is followed by oocyte activation, which is primarily triggered via sperm-derived factors, inducing a More >

Abstract Overview: Surgical management of benign prostatic hyperplasia (BPH) has evolved significantly, incorporating various minimally invasive procedures aimed at reducing morbidity and optimizing patient outcomes. Despite advancements, transurethral approaches continue to pose risks such as urethral strictures and urinary incontinence due to mechanical and thermal stress. To address these limitations, the Suprapubic Transvesical Adenoma Resection of the Prostate (STAR-P) was developed, offering a direct suprapubic route that bypasses the urethra entirely. Recent studies have validated STAR-P as both feasible and safe, emphasizing advantages such as enhanced visualization of the urinary sphincter, minimized urethral trauma, effective hemostasis,… More >

Abstract Varicocele (VC) is widely recognized as a prevalent and clinically significant cause of male infertility. However, the comprehensive pathogenic mechanisms underlying VC development and progression remain incompletely understood, creating an important knowledge gap in the field of andrology. This review establishes that VC pathogenesis centers on abnormal vascular remodeling and integrates multiple contributing elements, including anatomical abnormalities, biochemical disturbances, genetic factors, low body mass index (BMI), age, and specific sports habits, while secondary varicoceles are primarily induced by compressive pathologies.

Abstract Background: Ureteroenteric anastomotic stricture is a common complication after ureteral diversion with radical cystectomy, which leads to hydronephrosis, infection, and chronic renal failure. Although ureteroneocystostomy is reliable, its high degree of invasion often causes great damage and postoperative complications in patients. Therefore, we offer a new endoscopic approach with relatively limited invasion for severe obstructions such as ureteroenteric anastomotic atresia. Case Description: A 65-year-old man underwent radical cystectomy and urinary diversion of orthotopic neobladder and standardized chemotherapy for high-risk non-muscle-invasive bladder cancer.

Case Description: A 10-year-old girl presented with recurrent abdominal pain and ultrasound evidence of left hydroureteronephrosis. Magnetic resonance imaging (MRI) and three-dimensional (3D) reconstruction revealed a 30 cm blind-ending ureter. Robotic-assisted excision (Da Vinci Xi) was performed safely, preserving adjacent structures. Histology confirmed a nonfunctional ureteral remnant. Conclusions: DBU is a rare duplication variant.

Abstract Background: Penile augmentation through injectable substances is becoming increasingly common. A growing number of aesthetic clinics are developing penile enlargement procedures using various injectable materials. Although these procedures are now performed in more controlled and medically supervised environments, their long-term outcomes remain poorly understood. The promotion of such medical treatments contributes to an increasing interest among adult males in self-injection as a method to alleviate psychological distress associated with penile size concerns. At the same time, access to injectable substances through unofficial or unregulated sources has become increasingly easy. Tor our knowledge, we report the… More >

Abstract Background: We present a case of two major complications following insertion of a nephrostomy managed in a minimally invasive way. Our case is the first in the literature to describe this minimally invasive treatment technique for colon perforation in a completely asymptomatic patient. Case Description: A 75-year-old female patient with a history of bilateral obstructive uropathy secondary to bilateral radiation-induced ureteric strictures attended for bilateral nephrostomy placement. The patient had a history of endometrial cancer, treated previously by total hysterectomy and bilateral salpingo-oophorectomy with adjuvant chemo-radiotherapy and brachytherapy. Her recovery had been further complicated by the… More >

Abstract Background: Prostate cancer is a common malignancy, with many men on active surveillance for localized, low-risk disease also experiencing lower urinary tract symptoms (LUTS) from benign prostatic hyperplasia (BPH). Water Vapor Thermal Therapy (WVTT) is a minimally invasive BPH treatment, but its safety and efficacy in this setting are unclear. Case Description: We report three men with localized PCa on active surveillance who underwent WVTT for LUTS. Conclusions: WVTT appears safe and potentially effective in treating LUTS, especially in those with lower-risk disease and smaller prostate volumes. Further research is needed to confirm safety, efficacy, and More >
