Summary
This case study highlights renal papillary necrosis, a condition causing kidney damage. Transurethral procedures successfully treated the obstruction, offering a minimally invasive therapeutic option.
Area of Science:
- Nephrology
- Urology
Background:
- A 66-year-old female with a history of chronic analgesic use presented with symptoms of fever and right flank pain.
- Initial evaluation revealed right hydronephrosis and renal failure, necessitating referral to urology.
Observation:
- Retrograde pyelography demonstrated ureteral obstruction with filling defects.
- Ureteroscopy identified black-brown tissue specimens, later identified as necrotic renal papilla.
- A similar episode occurred in the left upper urinary tract four months later.
Findings:
- Histological examination confirmed necrotic transepithelial tissues, indicative of renal papillary necrosis.
- Ureteral obstruction was successfully managed with ureteral stent placement and conservative therapy.
Implications:
- This is the first reported case of renal papillary necrosis managed by transurethral procedures in Japan.
- Transurethral intervention offers a viable, minimally invasive treatment for renal papillary necrosis.
- Conservative management with ureteral stenting can be effective in resolving obstruction.
