Effect of preoperative estrogen on complications after proximal hypospadias repair: A randomized controlled trial

Akash Bihari Pati, Pritinanada Mishra, Santosh K Mahalik et al. · 2023 · Indian Journal of Urology

Introduction: Proximal hypospadias repair has many postoperative complications such as urethrocutaneous fistulae, wound dehiscence, and urethral stricture. The beneficial effect of estrogen to promote wound healing has been known. We designed a study to determine whether preoperative stimulation of tissue with estrogen can reduce the postoperative complications associated with wound healing in patients undergoing hypospadias repair. Methods: Patients with proximal hypospadias requiring two-stage repairs (chordee correction followed by urethral tubularization) were randomized to estrogen and co

Serum estradiol levels decrease after oophorectomy in transmasculine individuals on testosterone therapy

Sahil Kumar, Elise Bertin, Cormac O'Dwyer et al. · 2023 · Asian Journal of Andrology

Transmasculine individuals, considering whether to undergo total hysterectomy with bilateral salpingectomy, have the option to have a concomitant oophorectomy. While studies have evaluated hormone changes following testosterone therapy initiation, most of those patients have not undergone oophorectomy. Data are currently limited to support health outcomes regarding the decision to retain or remove the ovaries. We performed a retrospective chart review of transmasculine patients maintained on high-dose testosterone therapy at a single endocrine clinic in Vancouver, British Columbia, Canada. Twe

Which localization method is optimal in ESWL: fluoroscopy or ultrasonography?

Dursun Baba, Necati Ekici, Arda Taşkın Taşkıran et al. · 2025 · BMC Urology

Abstract Background Urinary stone disease is a common urological disorder, particularly among middle-aged individuals. Extracorporeal Shock Wave Lithotripsy (ESWL) is often the first-line treatment for kidney and ureteral stones. Traditionally, fluoroscopy is used for stone targeting in ESWL, but it exposes patients and clinicians to radiation and cannot visualize non-opaque stones. Ultrasonographic targeting eliminates these issues. This study compares the advantages and disadvantages of fluoroscopy and ultrasound-targeted ESWL. Methods At Düzce University Hospital, 100 patients with radio-op

Repository corticotropin injection versus corticosteroids for protection against renal damage in a focal segmental glomerulosclerosis rodent model

Kyle Hayes, Elizabeth Warner, Chris Bollinger et al. · 2020 · BMC Nephrology

Abstract Background Focal segmental glomerulosclerosis (FSGS) causes renal fibrosis and may lead to kidney failure. FSGS and its common complication, proteinuria, are challenging to treat. Corticosteroids are ineffective in many patients with FSGS, and alternative treatments often yield suboptimal responses. Repository corticotropin injection (RCI; Acthar® Gel), a naturally sourced complex mixture of purified adrenocorticotropic hormone analogs and other pituitary peptides, may have beneficial effects on idiopathic FSGS via melanocortin receptor activation. Methods Two studies in a preclinical

Comparison of estimated glomerular filtration rate of marginal versus standard renal allograft: A prospective cohort study

Somendra Bansal, Ketankumar G Rupala, Prasun Ghosh et al. · 2021 · Indian Journal of Urology

Introduction: The end-stage renal disease (ESRD) population is increasing worldwide and organ shortage is an important issue. The disparity between the availability of organs and waitlisted patients for transplants has forced many transplant centers across the world to use marginal kidney donors. We assess and compare postoperative estimated glomerular filtration rate (eGFR) in patients who received a graft from marginal renal donor (MRD) versus those who received a graft from standard renal donor (SRD). Methods: A total of 214 patients with ESRD underwent open live donor renal allografting fr
