Background: Routine intraoperative cystoscopy is often advocated to improve the diagnosis of ureteral obstruction in gynecologic surgery. It is possible for ureteral obstruction to occur in the immediate postoperative period and thus can be missed by cystoscopy.
Case: A patient had an anterior vaginal repair and transobturator sling. Intraoperative cystoscopy showed no abnormalities and demonstrated ureteral patency. Subsequently she developed unilateral hydronephrosis. Cystoscopy is advocated in similar cases but is not certain to rule out the occurrence of hydronephrosis in the postoperative period.
Conclusion: Even if cystoscopy is performed routinely following gynecologic surgery, hydronephrosis is still a possibility, and the diagnosis should not be dismissed out of hand.

Introduction: There is equipoise among pediatric urologists regarding endoscopic versus surgical intervention for symptomatic Grade 4-5 Vesicoureteric Reflux (VUR), particularly in infancy. Our aim was to assess outcomes of first-line endoscopic treatment in all cases of symptomatic Grade 4-5 VUR and we hypothesised that using endoscopic Dx/HA as first line management for primary VUR would obviate the need for ureteric reimplantation in the majority of cases.
Methods: Retrospective single-surgeon analysis of consecutive patients with primary Grade 4-5 VUR over 15 years.

Bladder invasion by appendiceal cancer resulting in a vesico-appendiceal fistula is an uncommon occurrence. Both radical tumor removal and functional preservation of the bladder are desirable in the surgical treatment of this disease, and there are few reports on detailed surgical methods. Here, we describe a case of primary appendiceal mucinous carcinoma with bladder invasion treated with robotic laparoscopy and endoscopy cooperative surgery (RECS).

Purpose: To investigate the effect of the degree of hydronephrosis on extracorporeal shockwave lithotripsy (SWL) success in patients who underwent SWL due to upper ureteral stones.
Methods: Medical records of 878 patients who underwent SWL were retrospectively reviewed. Patients with isolated unilateral 6-10 mm radiopaque upper ureteral stones above the upper border of the sacroiliac joint were included in the study.

A 50-year-old patient with a prior history of chronic smoking presented to the emergency department with diffuse abdominal pain, primarily localized to the right hypochondrium and epigastric region, along with nausea, but without fever, vomiting, or urinary symptoms. Laboratory tests were largely unremarkable except for isolated hematuria and a mildly elevated CRP. Given the atypical clinical presentation, a 3-phase abdominal CT scan (without contrast, portal, and delayed phases) was conducted, revealing a horseshoe kidney with an obstructing 4 mm stone at the right ureteral meatus.

Graphene quantum dots (GQDs) have received much attention for their biomedical applications, such as bioimaging and drug delivery. Additionally, they have antioxidant and anti-inflammatory properties. We used GQDs to treat renal fibrosis and confirmed their ability to protect renal cells from excessive oxidative stress in vitro and in vivo.
