Laparoscopic dismembered pyeloplasty is a minimally invasive, safe and effective therapy for pelvi-ureteric junction obstruction with low morbidity, shorter convalescence and excellent outcomes. To maximize an efficacious outcome, minimally invasive treatment of this condition requires preoperative planning with adequate imaging, but the role of retrograde pyelography remains controversial. We present a report in which retrograde pyelography accurately contributed to the perioperative diagnosis of ureteral fibroepithelial polyps, subsequently altering surgical management.

A 14-year-old boy developed hydronephrosis and worsening renal function due to fibroepithelial polyps of the bladder and left ureter at the age of 12 years. The endoscopic treatment of ureteral polyps was attempted by his previous doctor; however urethral stricture and ureteral stricture developed and was untreatable. Therefore, he was referred to our hospital for further reconstructive treatment.

Arterio-ureteral fistula (AUF) is a rare condition affecting nearby adult-only patients. Patients usually present with hematuria, often starting as intermittent hematuria which frequently increases, and may lead to hemorrhagic shock. Without rapid diagnosis and prompt treatment, AUF can be lethal.

The intrarenal reflux is caused by impaired emptying of the renal pelvis, that leads to increased intrarenal pressure. Increased pelvis pressure can be the result of a variety of states. The most common causes are acute upper urinary tract obstruction or overfilling of the pelvis during retrograde intrarenal surgery (RIRS) or retrograde pyelography.

Article Synopsis
- Salmonella is a major foodborne pathogen linked to gastrointestinal diseases, but has not commonly been reported to cause urinary tract infections, particularly with Salmonella Typhimurium.
- A 49-year-old woman with upper ureteral stricture underwent robotic ureteroplasty, later developing a urinary infection with Salmonella typhi and E. coli, treated successfully with antibiotics.
- The case indicates that urinary tract infections may not significantly impact the survival of grafts used in surgery, suggesting effective antimicrobial therapy can keep grafts viable during recovery.
