Article Synopsis
  • - The study investigates how heavy metals and trace elements (HMTE) contribute to bladder cancer (BC), focusing on mechanisms such as mitochondrial dysfunction, oxidative stress, and specific protein kinases.
  • - Researchers analyzed samples from 125 BC patients and 72 controls, measuring various heavy metals and assessing genetic markers related to mitochondrial function and oxidative stress using advanced laboratory techniques.
  • - Results revealed that elevated levels of several heavy metals in BC tissues correlated with increased expression of certain genes and markers associated with mitochondrial dysfunction and oxidative stress, highlighting the need to reduce exposure to these toxic elements to potentially lower BC risk.

Background: Our center policy is to promote right nephrectomy for pre-menopausal live donor donors. This is based on the traditional belief that ureteral obstruction and subsequent urinary tract infections (UTIs) of post-donation pregnancies would be more frequent among female donors with a solitary right (compared to left) kidney. Studies that support or dismiss our policy are lacking.

Background: Blood oxygen level dependent-magnetic resonance imaging (BOLD-MRI) is a non-invasive functional imaging technique that can be used to assess renal allograft dysfunction.

Purpose: To evaluate the diagnostic performance of BOLD-MRI using a 3-T scanner in discriminating causes of renal allograft dysfunction in the post-transplant period.

Material And Methods: This prospective study was conducted on 112 live donor-renal allograft recipients: 53 with normal graft function, as controls; 18 with biopsy-proven acute rejection (AR); and 41 with biopsy-proven acute tubular necrosis (ATN).

Objectives: To report the incidence, predictors, the impact of bladder perforation (BP), and our protocol of management in patients who underwent trans-urethral resection of bladder tumor (TURBT).

Methods: This is a retrospective study, between 2006 and 2020, on patients who underwent TURBT for non-muscle-invasive bladder cancer (NMIBC). Bladder perforation was defined as any full thickness resection of the bladder wall.

Objective: To study the necessity of pre-transplant programmed bladder cycling (PBC) in patients with defunctionalized bladder (DB).

Method: This RCT included renal transplant (RT) candidates with DB. Eligible patients were assigned to 2 groups, group I underwent PBC before RT and group II underwent direct RT into the DB.

In the process of urinary stone formation, several heavy metals and trace elements (HMTE) have been identified among the major constituents of the calculi. The micro-elements within the stones cannot be identified by ordinary laboratory analytical techniques, the latter can only detect the major crystalline component. The objective of the present study was to evaluate the different types of HMTE (no.

Objective: To evaluate female sexual function (FSF) after renal transplantation (RT) and compare it to an age-matched normal females (control).

Material And Methods: The study included 100 sexually active RT females in child-bearing period. Sexual function was evaluated with Female Sexual Function Index (FSFI).

Objective: To present long-term outcome of Yang-Monti ileal ureter, with a focus on patients with mild/moderate loss of kidney function and solitary kidney.

Patients And Methods: Between March 2001 and December 2019, Yang-Monti ileal ureter was performed on 36 patients with ureteric defects and median age 46.5 years.

Article Synopsis
  • The study evaluated surgical complications, febrile urinary tract infections (UTIs), graft function, and 5-year graft survival rates in renal transplant patients who had undergone augmentation cystoplasty (AC), comparing them to those with normal urinary tracts.
  • Results showed no significant difference in surgical complications or hospital readmission between AC patients, though those with normal tracts had fewer surgical issues and febrile UTIs.
  • While patients with AC had more complications and UTI episodes, their 5-year graft survival rates were similar to the control group, suggesting that ureterocystoplasty (UC) is preferred when augmentation is necessary.

Background: De novo malignancy is a worrying complication after kidney transplantation; the type of which may vary due to factors such as the prevalence of viral infection and race. Kaposi sarcoma used to be the most common malignancy among our patients constituting more than one-third of cancers. Nevertheless, we noticed that Kaposi sarcoma has not been observed for a long period.

Bacteria is recognized as opportunistic tumor inhabitant, giving rise to an environmental stress that may alter tumor microenvironment, which directs cancer behavior. In vitro infection of the T24 cell line with E. coli was performed to study the bacterial impact on bladder cancer cells.

Objectives: To prospectively evaluate the value of early urine cytology (EUC) after the primary transurethral resection of bladder tumor (TURBT) of nonmuscle invasive bladder cancer (NMIBC) for the prediction of positive biopsy findings on repeat TURBT.

Methods: After approval of institutional review board, patients who underwent TURBT for NMIBC between February 2014 and July 2018 were included in the study. Patients with concomitant Carcinoma in Situ (CIS), upper tract urothelial tumors, biopsy proven muscle invasion, or low-risk NMIBC (single, primary, Ta, and G1 tumor) were excluded.

Toxic metals and trace elements (TMTE) are linked to the development of several human cancers. Many reports have documented the association between some TMTE and renal cell carcinoma. In this work, we assessed the presence (qualitative) and evaluated the concentration (quantitative) of 22 TMTE in three groups of kidney tissue samples: renal cell carcinoma (RCC), adjacent non-cancerous, and control kidney tissues from cadavers.

Purpose: To compare the outcome of shock wave lithotripsy (SWL) for upper lumbar ureteric stones using the alternating bidirectional approach versus the standard approach during the first session.

Methods: Our study was a randomized controlled trial including patients with single radio-opaque stone < 1 cm located in the upper lumbar ureter (from the ureteropelvic junction till the level medial to the lower margin of the kidney). SWL was conducted using electromagnetic Dornier Gemini Lithotripter.

Background: Bladder cancer is the most common urological malignancy with a high tendency for progression and recurrence. So far, no reliable diagnostic marker is present with 100% sensitivity and specificity. Netrins are related to laminin proteins, and were first discovered to be involved in neural development.

De novo renal allograft tumors were reported sporadically. Most of them were small, low-grade, and papillary renal cell carcinoma (RCC) type. A 46-year-old male presented with hematuria three decades after the first transplant.

Introduction: Accepting donors with renal lesion amenable for pre-transplant management with no suspected long-term harm seems to expand the live-donor pool. We aimed to assess the long-term outcome of live-donor renal transplantation with incidentally discovered renal angiomyolipoma (AML) during routine evaluation of donors.

Patients And Methods: A retrospective evaluation of incidentally discovered AML, during live-related-donor evaluation, was performed.

Article Synopsis
  • - The study aimed to evaluate the effectiveness of tolterodine in treating nocturnal urinary incontinence (NUI) in patients who underwent ileal orthotopic neobladder surgery, using a randomized, placebo-controlled crossover design.
  • - Results showed significant improvements in urinary incontinence symptoms among those taking tolterodine, with 77.9% of patients in the treatment group reporting improvements compared to only 5.5% in the placebo group.
  • - While tolterodine appears effective for NUI post-surgery, some patients experienced side effects like dry mouth, indicating the need for further research on long-term effects and urodynamic outcomes.

Objective: To compare recovery outcomes between laparoscopic donor nephrectomy (LDN) and open donor nephrectomy within a specified enhanced recovery program (ERP) for left kidney donations.

Patients And Methods: A phase III randomized trial was conducted between January 2013 and June 2015; eligible left-side donors were randomized to laparoscopic or open donor nephrectomy in a 1:1 ratio with recovery optimized within a standardized ERP.
