Publication Clinicopathological Outcome of Early and Late Onset Renal Cell Carcinoma: An Observational Study(Institute of Medicine, Tribhuvan University, 2024) Pandit, Durga; Phuyal, Anjit; Gyawali, Milan; Guragain, Bipin; Parajuli, Purushottam; Pradhan, Manish Man; Poudyal, Sujeet; Chapagain, Suman; Luitel, Bhojraj; Chalise, Pawan Raj; Sharma, Uttam Kumar; Gyawali, PremAbstract: Introduction Renal cell carcinoma (RCC) is considered a disease of old age and is typically found in the 6th-8th decade of life. The diagnosis of RCC is increasing more rapidly in younger age patients. This study was conducted to evaluate the clinicopathological pattern and outcome of early onset RCC and compare them with the older age group patients. Methods This was a single center observational study. All the patients undergoing radical or partial nephrectomy during the period of November 2019 to October 2022 for renal masses and whose final histopathology report showed RCC were included in the study. Clinicopathological patterns and outcome were compared between the two age groups. Results Among 47 patients, 17 (36.2%) patients were at or below the age of ≤46 years and 30 (63.8%) patients in older age group. There was significant difference in male (29): female (18) ratio between the two age groups (p < 0.005). Younger age patients (≤46 yrs) had higher stage of disease at presentation compared with the older age (>46 yrs) patients [tumor extension into major veins and perinephric tissue (T3) and above 26 vs 21] and they had significantly higher mortality rate (29.4% vs 3.3%, p =0.01). Conclusion Patients aged ≤46 years of age were more frequently affected by RCC with female predominance. Younger age group had higher stage of disease at presentation with higher mortality in comparison to older age group.Publication Periprocedural Antibiotic Prophylaxis Practice during Diagnostic Cystoscopy: An Observational Study(Institute of Medicine, Tribhuvan University, 2024) Phuyal, Anjit; Chapagain, Suman; Chalise, Pawan Raj; Luitel, Bhojraj; Poudyal, Sujeet; Gyawali, Prem RajAbstract: Introduction Both American and European guidelines recommend against routine use of antibiotics prophylaxis in routine cystoscopy. But studies have shown that antibiotics use during cystoscopy is discordant from available guideline recommendations even in Europe and America. This study aims to identify prophylactic antibiotic uses pattern of Nepalese Urologists and measure adherence to guidelines. Methods An online questionnaire based self-reported survey was conducted among the practicing urologists of Nepal, who were full members of Nepalese Association of Urologists. The questionnaires in Google Forms were sent via emails to 96 urologists of Nepal. Fully completed questionnaires were analyzed. Results Out of 96 emails 58 fully filled questionnaires were received and analyzed. Routine prophylactic antibiotics prescription before cystoscopy was reported by 43 (74.1%) urologists. Availability of Antibiotic Stewardship/Antimicrobial Stewardship team at their workplace was reported by 31 (53.4%) urologists and 19 (32.8%) urologists reported of having Standard Operating Procedure regarding peri-procedural antibiotic prophylaxis at their workplace. No verification of the answers were done and reported as received. Conclusion Peri-procedural antibiotic prophylaxis practice during cystoscopy was highly prevalent.Publication Prediction of Urosepsis after Percutaneous Nephrolithotomy using Neutrophil-Lymphocyte Ratio(Institute of Medicine, Tribhuvan University, 2025) Lacoul, Robal; Luitel, Bhojraj; Chapagain, Suman; Poudyal, Sujeet; Pradhan, Manish Man; Chalise, Pawan RajAbstract: Introduction: Percutaneous nephrolithotomy (PCNL) is the preferred modality treatment for kidney stones >2 cm. Prediction of postoperative infection remains a major concern. The neutrophil-to-lymphocyte ratio (NLR) is an inexpensive and readily available marker of systemic inflammation and has shown potential in predicting infection and sepsis. This study aims to investigate the utility of preoperative NLR in predicting urosepsis following PCNL. Methods: A prospective observational study was conducted on 86 patients undergoing PCNL at Maharajgunj Medical Campus, Institute of Medicine, Tribhuvan University, Nepal. Preoperative NLR was calculated from complete blood counts. Postoperative infectious outcomes were analyzed, logistic regression and receiver operating characteristic (ROC) curve analyses were performed to assess NLR’s predictive value. Results: Post-PCNL fever occurred in 43 patients (50%) and sepsis in 16 patients (18.6%). Patients with sepsis had significantly higher preoperative NLR (3.55 ± 2.25 vs. 1.82 ± 0.68, p < 0.001). An NLR cut-off of 1.86 predicted sepsis with area under curve (AUC) 0.829, 93.8% sensitivity and 68.6% specificity (p < 0.001). Higher risk of sepsis was seen in patients with chronic kidney disease (37.5%), preoperative percutaneous nephrostomy (46.7%), prior UTI admission (30.3%), staghorn stones (50%), longer operative time (99.69 ± 31.12 vs 78.26 ± 34.23 minutes). Conclusion: Preoperative NLR may be a useful marker for identifying patients at increased risk of sepsis after PCNL, particularly in patients with complex stones and value >1.86. Further large-scale studies are needed to validate its role and compare it with other established biomarkers.Publication Prevalence and Antimicrobial Susceptibility of Multi-Drug Resistant Uropathogens in a Tertiary Hospital in Nepal: A One-Year Audit(Nepal Medical Association, 2025) Pradhan, Manish Man; Sharma, Sangita; Poudyal, Sujeet; Gnyawali, Diwas; Adhikari, Suman; Chapagain, Suman; Luitel, Bhojraj; Kattel, Hari Prasad; Chalise, Pawan RajAbstract Introduction: Antibiotic resistance, especially multidrug resistance, poses a global public health threat. It complicates the treatment of infections like urinary tract infections, leading to treatment failure, extended hospital stays, and increased healthcare costs. Empirical antibiotic therapy, guided by local resistance patterns, is crucial for patient outcomes and infection prevention. This study analyzes urine cultures from TU-Teaching Hospital from January to December 2024 to investigate the prevalence and antimicrobial susceptibility of multidrug-resistant uropathogens. Methods: This was a retrospective, observational hospital-based study conducted in a tertiary care center after obtaining the ethical approval from Institutional Review Committee (IRC), (Approval reference: 470 (6-11) E2). All samples tested fromJanuary 1, 2024, to December 31, 2024 the period included in the study. Data were collected from the Electronic health records of the Microbiology department and analyzed using Microsoft Excel 16.0.0 and SPSS 30.0.0 software to determine the urine culture positivity rate, the prevalence of multidrug-resistant uropathogens, and their antimicrobial susceptibility patterns with a specific focus on resistance to commonly prescribed antibiotics. Results: A total of 25,315 urine samples were collected for urine culture and sensitivity testing during the study period. Significant bacterial growth was seen in 4,557 (18%). Multidrug resistance was seen in 3,448 (75.66%). The most frequently isolated organisms were Escherichia coli 1724 (50%), Klebsiella 154 (17.7%). E. coli, Klebsiella, Enterococcus, Citrobacter, Pseudomonas, and Acinetobacter showed resistance to Ceftriaxone (74.61–92.20%), Amoxycillin+Clavulanate (67.58–97%), and Nitrofurantoin (52.29–89.55%) across selectively tested isolates. Conclusions: Urine samples demonstrated a high prevalence of multidrug resistance to routinely prescribed antibiotics, even among second-line parenterally administered antibiotics. Only costly third-line antibiotics exhibited low resistance.
