Background: Laparoscopic ureterolithotomy (LU) is a standard intervention for large proximal ureteral stones. A significant technical consideration is whether to suture the ureterotomy site or utilize a sutureless approach to potentially minimize operative time and surgical morbidity. This study aimed to compare the perioperative outcomes and safety profiles of sutureless vs conventional sutured transperitoneal LU.Methods: We conducted a retrospective comparative study of 60 patients with proximal ureteral stones >15 mm who underwent transperitoneal LU between January 2023 and March 2025. Patients were divided into two groups: a sutured group (n=30), where the ureterotomy was closed with interrupted sutures, and a sutureless group (n=30), where the site was left unsutured over a Double-J stent. Primary and secondary outcomes included operative time, urinary leakage volume (measured via drain output), hospital stay, and postoperative renal function.Results: Baseline demographics and stone characteristics were comparable between the groups. The sutureless technique was associated with a significantly shorter mean operative time (2.2±0.3 h vs 2.7±0.4 h; p<0.001). While the duration of ureteral stenting was statistically longer in the sutureless group (17.7±4.4 days vs 16.1±5.2 days; p=0.050), this difference was clinically marginal. There were no significant differences in the volume of postoperative urinary leakage (p=0.066), hospital stay, or changes in serum creatinine and hemoglobin levels. No cases of urinoma or ureteral stricture were observed in either cohort during the early follow-up period.Conclusions: The sutureless technique for laparoscopic ureterolithotomy is a safe and efficient alternative that significantly reduces operative time without increasing the risk of major complications. Although it involves a statistically longer stenting period, the overall clinical outcomes are comparable to the sutured technique. The choice of approach should be individualized based on surgeon expertise and patient-specific anatomical factors.

Background: Percutaneous nephrolithotomy (PCNL) is the gold standard for managing large renal calculi; however, data on its long-term efficacy in resource-limited settings such as Yemen are scarce. We evaluated the outcomes and complications of PCNL surgery in resource limited settings over a nine-year period in a high-volume centre in Ibb City, Yemen.Methods: We conducted a retrospective analysis of 1,458 patients who underwent PCNL between October 2016 and June 2025. Data included patient demographics, stone characteristics, surgical techniques (standard, mini-PCNL, and supine), and outcomes. The stone-free rate (SFR) was defined as the absence of fragments greater than 4 mm on follow-up imaging at three months. Complications were classified using the Clavien-Dindo system.Results: The cohort comprised 763 (52.3%) males and 695 (47.7%) females with a mean age of 43.8±17.5 years (range: 2-87 years). Staghorn calculi were present in 647 cases (44.4%). Prone lower-pole access was the predominant approach (58.2%), with a progressive institutional shift toward mini-PCNL (5.7%), supine PCNL (3.1%), and ultrasound-guided access (1.4%) in later years. The primary stone-free rate after a single session was 76.0%, increasing to a final SFR of 92.6% following auxiliary interventions including repeat PCNL, ureteroscopy (2.8%), ESWL (1.5%), and conservative management of clinically insignificant residual fragments (6.0%). Major complications (Clavien-Dindo Grade III-V) occurred in 1.44% of cases, including colonic perforation (0.41%) and conversion to open surgery (0.62%). Mortality rate was 0.14% (n=2). Minor complications (Grade I-II) affected 17.4% of patients, predominantly postoperative pain (7.3%) and transient fever (5.3%).Conclusions: This large series demonstrates that PCNL can be performed with high stone-free rates and acceptable morbidity in resource-limited settings despite a high prevalence of complex staghorn calculi. The progressive adoption of miniaturized and supine techniques reflects institutional adaptability and confirms the feasibility of implementing contemporary endourological standards in low-resource environments.
Khat chewing, poly-substance use, and lower urinary tract symptoms: A cross-sectional analysis among Yemeni Medical University students

Archivio Italiano Di Urologia E Andrologia, 2026
Background: Khat (Catha edulis) chewing is highly prevalent in Yemen, but its potential urological effects are poorly characterized. The pharmacological action of its alkaloids on alpha-adrenergic receptors suggests a plausible link to voiding dysfunction. This study explored the association between khat chewing patterns, concurrent stimulant use, and lower urinary tract symptom (LUTS) severity.Methods: In this cross-sectional study, 112 medical and paramedical university students from seven Yemeni governorates completed a structured digital questionnaire being recruited via convenience sampling. LUTS severity was assessed using the International Prostate Symptom Score (IPSS). Exposure variables included khat chewing (status, duration, daily hours), coffee, soda, and tobacco use. Participants were categorized into poly-substance use clusters. Multivariable linear and logistic regression models identified predictors of LUTS, adjusting for confounders including age and sex.Results: Among participants (mean age 24.3±5.7 years), 86 (76.8%) were current khat chewers. A significant dose-response relationship was observed. Each additional hour of daily chewing was associated with a 1.85-point increase in IPSS score (95% CI: 1.32-2.38; p<0.001). The concurrent use of khat, coffee, and soda was associated with the highest mean symptom score (21.4) and a significantly elevated adjusted odds ratio for severe LUTS (IPSS ≥20) of 17.15 (95% CI: 6.28-47.10; p<0.001) compared to non-users. Daily coffee consumption and tobacco smoking were also independent predictors of higher IPSS scores.Conclusions: Among this sample of Yemeni university students, khat chewing demonstrated a strong, dose-dependent association with more severe LUTS. This association was markedly amplified by the co-use of caffeine-containing beverages. While the cross-sectional design precludes causal inference, these findings highlight a potential public health concern and underscore the need for longitudinal studies and clinical awareness of urological symptoms in khat-chewing populations.

Nephro Urology Monthly, 2026
Background: Percutaneous nephrolithotomy (PCNL) is the gold-standard treatment for large renal stones. The prone position, traditionally used, may impair cardiopulmonary function due to thoracoabdominal compression, whereas the supine position offers potential physiological and practical advantages. Objectives: To compare intraoperative hemodynamic and respiratory stability between supine and prone PCNL. Methods: This single-center retrospective cohort study analyzed 40 patients (supine = 20, prone = 20) undergoing PCNL between January-December 2023. Inclusion criteria were age ≥ 18 years, American Society of Anesthesiologists (ASA) I/II, and renal pelvic stones ≥ 2 cm. Groups were matched for age, sex, BMI, stone size, and ASA status. All procedures followed a standardized anesthetic protocol. Primary outcomes were intraoperative blood pressure, heart rate (HR), oxygen saturation (SpO₂), and end-tidal carbon dioxide (ETCO₂). Secondary outcomes included fluid administration, anesthesia duration, and operative time. Data were analyzed using independent t-tests; estimates are unadjusted. Results: The prone position was associated with significant hemodynamic instability, manifesting as profoundly lower SBP and DBP and a higher HR throughout the procedure (e.g., at 80 min: SBP 89.5 ± 4.6 vs. 133.3 ± 12.4 mmHg, P < 0.001; HR 114.8 ± 11.8 vs. 75.8 ± 3.4 bpm, P < 0.001). Pulmonary function was also compromised in the prone group, as evidenced by significantly lower SpO₂ (nadir: 96.8 ± 1.3% vs. 100%, P < 0.001) and elevated ETCO₂ (peak: 40.9 ± 1.2 vs. 34.9 ± 0.4 mmHg, P < 0.001). Furthermore, patients in the prone position required greater intraoperative fluid resuscitation (1950.0 ± 484.0 mL vs. 1475.0 ± 472.3 mL, P = 0.003) and experienced a longer anesthesia duration (158.3 ± 25.0 vs. 118.3 ± 18.3 min, P < 0.001). Operative time, complications, and stone-free rates (SFRs) were comparable among the groups. Conclusions: Supine PCNL may offer superior intraoperative physiological stability, with improved hemodynamics, preserved respiratory function, reduced fluid needs, and shorter anesthesia duration, without compromising surgical efficacy. These findings support supine positioning as a potentially safer alternative for selected patients, though further prospective validation is warranted.
