Background: Retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) are two common procedures used to treat large renal stones. This work aimed to evaluate the safety and efficacy of flexible ureterorenoscopy with laser lithotripsy (FURSL) in the management of large renal stones in comparison with the gold standard PCNL for the management of large renal stones 25 – 40 mm in size.

Methods: This prospective study was carried out on 100 patients who received RIRS or PCNL for renal stones with sizes ranging from 25 mm to 40 mm. The research was composed of two groups: the PCNL group (n= 50) and the FURSL group (n= 50). with exclusion of cases with anatomical abnormalities, cases with history of previous surgery patient with coagulopathy.

Results: The location of the stone was significantly varied among both groups (P value =0.006). Operative time was significantly higher in Group FURS than Group PCNL (P value <0.001) and hospital stay was significantly lower in Group FURSL than Group PCNL (P value <0.001). Complications (fever, colonic injury, stein Struss, haematuria, and bleeding) were insignificantly variant among both groups. The total number of patients who needed auxiliary procedure like 2nd session of FURSL were significantly higher in Group FURSL than in Group PCNL (P value <0.001). need for ESWL as auxiliary procedures were insignificantly variant among both groups.

Conclusion: Both FURS and PCNL have shown safety and efficacy in managing sizable renal stones. The selection between each technique should be individual according patient factors and urologist preference.

Background: Gitelman syndrome (GS) is a rare autosomal recessive disorder caused by mutations in the SLC12A3 gene, which encodes the sodium-chloride (Na-Cl) cotransporter (NCC). GS is characterized by salt-losing tubulopathy, which leads to renal potassium loss, hypokalemia, metabolic alkalosis, hypocalciuria, hypomagnesemia, and hyperreninemic hyperaldosteronism. GS can increase the risk of developing type 2 diabetes mellitus.

Case presentation: We report the case of Japanese patient with GS who had suffered from hypokalemia for over a decade, and subsequently developed diabetes. The results of detailed biochemistry and diuretic stress tests suggested a diagnosis of GS.

Results: Genetic exome sequencing revealed both heterozygous c.835A>G (p.Met279Val) and homozygous c.791C>G (p.Ala264Gly) mutations in the SLC12A3 gene. Further in silico variant prediction and structural analyses revealed that the heterozygous c.835A>G (p.Met279Val) mutation in the SLC12A3 gene was the predominant pathogenic variant. Modeling and structural analyses suggested that this mutation contributes to the NCC salt-bridge conformation and leads to impaired Na-Cl transport.

Conclusion: We present a case of GS with a novel SLC12A3 gene mutation that has not been previously reported. Genetic testing and structural analysis are essential for the accurate diagnosis and understanding of the renal tubular pathology in GS.

Purpose: This study seeks to explore the lived experiences and viewpoints of individuals with Urinary Incontinence (UI) and evaluate how the condition affects their quality of life. Through comprehensive interviews, the research aims to identify the physical, emotional, and social effects of UI experienced by affected individuals. A particular emphasis is placed on gaining a deeper understanding of the cultural and contextual factors that may influence these experiences among Pakistani women. This research seeks to fill a gap in existing international questionnaires, which often overlook the religious aspects relevant to our cultural norms and spiritual context. The results will contribute to the development of a culturally sensitive and population-specific assessment tool.

Design: Qualitative study with content analysis.

Subjects and Setting: The study sample included 15 patients with a mean age of 35 years, diagnosed with urinary incontinence. All participants were recruited from the Urogynecology Clinics at Aga Khan University Hospital.

Methods: Fifteen audio recorded interviews were conducted. A qualitative content analysis using an inductive approach was conducted to organize and interpret the study’s findings.

Results: Six primary themes were identified, including (1) Impact on daily life activities (2) Impairment in religious practices (3) Influence on social and interpersonal relationships (4) Psychological impact (5) Coping mechanisms (6) Barriers to effective healthcare engagement.

Conclusions: The study results indicate that UI has a substantial impact on various aspects of women’s lives, affecting not only physical health but also emotional well-being, social engagement, daily activities, and religious practices. The study highlights that women utilize various coping strategies to manage their condition, yet encounter significant barriers in accessing effective healthcare services. These insights emphasize the importance of developing culturally appropriate assessment tools that incorporate religious aspects.

Radiation nephropathy is the damage to the renal parenchyma and blood vessels caused by ionizing radiation, and its mechanism of injury involves oxidative stress, DNA damage, cellular senescence, and other processes, among which oxidative stress plays an obvious role. In the case of excessive accumulation of oxidative stress products, it can lead to lipid peroxidation and iron distribution abnormalities caused by ferroptosis; the latter is involved in a variety of pathophysiological processes, while currently there is no role in radiation nephropathy. The present study sought to investigate the role of ferroptosis in radiation nephropathy, and the mechanism of FG-4592 in relieviating radiation nephropathy, C57BL/6 mice and TCMK-1 cell are separately irradiated with 12GY, 10GY X-ray to construct radiation nephropathy models in vivo and in vitro. Compared with the control group, X-rays promoted the occurrence of lipid peroxidation and ferroptosis, and oxidative stress and lipid peroxidation products were increased and antioxidant products were decreased in the X-rays-induced radionephropathy model; intervention in ferroptosis could alleviate radiation nephropathy, and FG-4592 could regulate lipid metabolism and oxidative reactions to ameliorate feroptosis and attenuate kidney injury through the modulation of HIF activity. In conclusion, in this study, transcriptome analysis was utilized to screen out the pathways involved in the regulation of radiation nephropathy, which provided the basis for the subsequent study of drug intervention in radioactive kidney injury. And FG-4592 had a certain anti-radiation effect in this experiment, which had a protective effect in radiation nephropathy. This study provides new ideas for the development of novel low toxicity, effective radiation-resistant agents.

Introduction: The study purpose was to analyze in consecutive periods our nearly 19-year experience in simultaneous pancreas-kidney transplantation (SPKT) with an emphasis on changes in practice that improved outcomes in the most recent era.

Methods: Single center retrospective cohort study of all SPKTs performed in two sequential eras: Era 1 (E1): 11/1/2001 – 12/31/2010; Era 2 (E2) 1/1/2011 - 8/12/20). Immunosuppression and management protocols were standardized in both eras.

Results: 255 consecutive SPKTs were analyzed (E1, n=126; E2, n=129). By design, E2 patients received organs from younger donors (mean E1 28.1 vs. E2 23.7 years) with shorter pancreas cold ischemia times (CITs, mean E1 16.8 vs. E2 13.4 hours, both p<0.05). In addition, donors with either hypertension or cerebrovascular cause of death were more common in E1 compared to E2 (both p<0.05). More E2 patients received alemtuzumab induction (52.4% E1 vs 97.7% E2, p<0.0001). One-year pancreas graft survival rates (PGSRs, 84.9% Era 1 versus 94.6% Era 2, p=0.02) and four-year PGSRs (70.6% E1 versus 85.5% E2, p=0.002) were significantly higher in E2 and by Kaplan-Meier analysis. In univariate analysis, alemtuzumab induction and E2 were associated with superior and longer pancreas CIT with inferior death-censored PGSRs. Only alemtuzumab induction had a significant (protective) effect on censored PGSR in the multivariate model.

Conclusions: In our experience, optimizing donor quality (younger donors without hypertension or cerebrovascular cause of death), minimizing pancreas CIT, and use of alemtuzumab induction are associated with improved outcomes following SPKT.
