OBJECTIVE: Very limited data are available exploring the potential influence of gender on Retrograde Intrarenal Surgery outcomes. This study investigates the gender-specific influence of ShuoTongureteroscopy (ST-urs) and Flexible Ureteroscopy (F-urs) surgeries on operation efficacy and patient recovery in a sample of the Somali population. MATERIALS AND METHODS: We enrolled 390 participants. Participants were stratified into four gender-specific subgroups based on ureteroscopy operation type: 27...

The treatment paradigm for high risk localized and advanced kidney cancer has been characterized by ongoing changes, with the introduction of vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR TKIs) and later with immune checkpoint blockade. In this article, we review how current evidence informs our decision-making on post-checkpoint inhibitor systemic therapies, the role of adjuvant and/or neoadjuvant therapies, and the role of cytoreductive nephrectomy in the evolving systemic therapy landscape...

AIM: To review our 10 years of experience with the endoscopic treatment of vesicoureteral reflux (VUR) in children, emphasizing the long-term efficacy of the "combined STING-HIT" technique. MATERIALS AND METHODS: A retrospective study was performed including all children with symptomatic VUR undergoing the cystoscopic injection of bulking agents from January 2013 to December 2022 in our pediatric tertiary referral center. Three different endoscopic techniques were adopted: the "combined STING-HIT" technique, the STING technique, and the HIT technique...

BACKGROUND: Since its introduction over two decades ago, the surgical laser has served in the lithotripsy of urinary calculi, resection of bladder tumours, bladder neck incisions, and prostate enucleation. Concerns regarding the safe use of holmium lasers have resulted in potentially excessive and overly precautious theatre regulations. We aimed to evaluate the preconceived impressions and practice patterns at a single site surrounding laser use in endourology. METHODS: We designed a three-part online questionnaire that could be accessed using a smart device or computer...

Primary bladder large cell neuroendocrine carcinoma (LCNEC) is a rare, aggressive neoplasm with high recurrence rates and poor prognosis. Traditional management has heavily relied on radical cystectomy, which, despite its aggressiveness, often results in unsatisfactory outcomes. Emerging evidence suggests the potential for less invasive, bladder-sparing approaches, yet detailed reports and long-term outcomes remain scarce. We report a groundbreaking case of a 59-year-old male diagnosed with primary bladder LCNEC, managed through a pioneering bladder-sparing multimodal treatment...

We report rare case of concomitant left nutcracker syndrome and right ureteropelvic junction obstruction (UPJO) on adult female patient diagnosed by CT urogram after she presented with intermittent bilateral flank pain. For this we did Anderson-Hynes pyeloplasty for right ureteropelvic obstruction, it was laparoscopic initially but due to difficulty of stenting it is changed to open. She had smooth post-op course then discharged on 3rd post-op day. Symptoms of nutcracker syndrome are not that much bothersome for the patient so we planned to follow her conservatively...

PURPOSE: Contact laser vaporization of the prostate (CVP) for benign prostatic hyperplasia is a widely accepted and safe procedure for elderly patients because of its lower bleeding risks. However, CVP lacks a postoperative pathological examination for prostate cancer. Concomitant prostate biopsy and CVP may complement this disadvantage; however, the risk of bleeding associated with this procedure remains unclear. This study aimed to evaluate the safety of a concomitant prostate biopsy and CVP...

OBJECTIVE: To assess the correlation of attenuation value measured as HU in Non-contrast computed tomography, stone size, location, fibre size and stone composition with Holmium: yttrium-aluminium garnet (Ho: YAG) laser parameters including, cumulative laser energy and final laser time. MATERIALS AND METHODS:  We prospectively analyzed 118 patients undergoing flexible/semirigid ureteroscopy and Holmium: YAG laser lithotripsy from October 2022 to October 2023 at Mogadishu Urological Centre...

About 75% of bladder cancers are detected as non-muscle invasive. High-risk patients have high progression risk. Although the standard is transurethral resection of bladder tumor plus full dose intravesical BCG for one to 3 years, due to the high risk of progression, radical cystectomy may be considered in specific cases. Although radical cystectomy is still the best approach for high-grade NMIBC from an oncological perspective, its high morbidity and impact on quality of life motivate studies of new strategies that may reduce the need for cystectomy...

PURPOSE: This study aimed to report the outcomes of hypospadias repair performed at a tertiary-level hospital during 2018 to 2021. METHODS: A retrospective chart review of 119 patients was performed. RESULTS: The most frequent coronal hypospadias cases were distal. However, the most common scrotal hypospadias cases were proximal. The average age at the time of the first surgery was 2.4 years (standard deviation, ±2.3 years). The tubularised incised plate technique was performed for 57 of these 119 patients...

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a histopathological diagnosis characterized by the increase in stromal cells and epithelial cells of the prostate gland in the transitional zone surrounding the urethra. Obesity is the risk factor of BPH. The most frequent cause of obesity is a high-fat diet (HFD). Obesity and HFD lead to pro-inflammatory conditions. One of the pathomechanisms for the occurrence of BPH is a low-degree inflammatory factor, one of which is the level of monocyte chemoattractant protein-1/MCP-1...

Acute kidney injury (AKI) is a common complication after surgery and the more complex the surgery, the greater the risk. During surgery, patients are exposed to a combination of factors all of which are associated with the development of AKI. These include hypotension and hypovolaemia, sepsis, systemic inflammation, the use of nephrotoxic agents, tissue injury, the infusion of blood or blood products, ischaemia, oxidative stress and reperfusion injury. Given the risks of AKI, it would seem logical to conclude that early identification of patients at risk of AKI would translate into benefit...

OBJECTIVE: Evaluation of the outcome of the miniaturized percutaneous nephrolithotomy in the treatment of nephrolithiasis with a lateral position based on the principle of a right triangle under the guidance of a C-Arm without contrast fluid. MATERIALS AND METHODS: Sixty-nine cases of Mini-PCNL with the assistance of a vacuum-assisted sheath in the lateral position were performed at Central Hospital from March 2021 to August 2022. Percutaneous renal access was under the guidance of a non-rotational C-arm without contrast medium, and we determined the puncture location and depth of the needle based on the principle of right triangles...

PURPOSE: This study examines the readability of online medical information regarding cloacal exstrophy (CE). We hypothesize that inappropriate levels of comprehension are required in these resources, leading to poor understanding and confusion amongst caregivers. METHODS: The Google and Bing search engines were used to search the terms "cloacal exstrophy" and "cloacal exstrophy treatment". The first 100 results for each were collected. Each webpage was analyzed for readability using four independent validated scoring systems: the Gunning-Fog index (GFI), SMOG grade (Simple Measure of Gobbledygook), Dale-Chall index (DCI), and the Flesch-Kincaid grade (FKG)...

BACKGROUND: With widespread adoption of technological advancements in everyday life, patients are now increasingly able and willing to obtain information about their health conditions, treatment options, and indeed expected outcomes via the convenience of any device than can access the worldwide web. This introduces another aspect of patient care in the provision of healthcare for the modern doctor. ChatGPT is the first of an increasing number of self learning programs that have been released recently which may revolutionize and impact healthcare delivery...

BACKGROUND: Many emerging uropathogens are currently identified by multiplex polymerase chain reaction (M-PCR) in suspected UTI cases. Standard urine culture (SUC) has significantly lower detection rates, raising questions about whether these organisms are associated with UTIs and truly cause inflammation. OBJECTIVE: To determine if microbes detected by M-PCR were likely causative of UTI by measuring inflammatory biomarkers in the urine of symptomatic patients. DESIGN SETTING AND PARTICIPANTS: Midstream voided urine was collected from subjects ≥60 years presenting to urology clinics with symptoms of UTI (n = 1132) between 01/2023 and 05/2023...

Lower urinary tract dysfunction not only interferes with the health-related quality of life of patients but may also lead to acute kidney injury and infections. To assess the bladder, urodynamic studies (UDS) have been implemented but the use of catheters leads to discomfort for the patient. Catheter-free long-term UDS would be useful and a potential solution could be ambulatory wireless devices that communicate via telemetry. Such sensors can detect pressure or volume. Numerous types of potential catheter-free sensors have been proposed for bladder monitoring...

OBJECTIVE: This study investigates the efficacy of physical therapy in treating chronic prostatitis grounded on the glandular duct blockage theory. METHODS: The study includes patients who were diagnosed and treated for chronic prostatitis between November 2022 and July 2023 at Renhui clinic in Jiangmen, Guangdong and Renhui frontline clinic in Shenzhen Guangdong. The recorded data includes the frequency of physical therapies including prostate massages, rectal probe high-frequency vibration treatment, and low-intensity extracorporeal shockwave therapy (Li-ESWT)...

BACKGROUND: Prostate cancer is often considered a disease of older men and this indeed fits with its peak incidence between 65-79 years of age. Reports of prostate cancer in men younger than 40 years of age and the outcomes of this age group following treatment are few in the literature. Here, we present the case of an unusual diagnosis of high grade prostate cancer in a very young man and outline early outcomes following treatment with robotic-assisted radical prostatectomy. CASE PRESENTATION: A 35-year-old male, intermittently taking finasteride for hair loss, was found to have an elevated prostate-specific antigen (PSA) of 12...

PURPOSE: This study aimed to evaluate what objectives are most important to men undergoing radical prostatectomy to allow treating physicians to personalize perioperative counselling and improve patient quality of life outcomes. MATERIALS AND METHODS: A predefined search protocol of the Medline and Embase databases was performed from database inception to May 2023. The search was limited to English language and full text. All articles with a specific consideration of patient objectives, preferences or reasons for decision to undergo radical prostatectomy were included for review...
