Abstract
BACKGROUND

Urothelial encrusted pyelo-ureteritis disease is an infrequent condition and there is no unified surgical treatment and reference standard to consult. We have used a minimally invasive endoscopic method to treat three such cases, which yielded excellent results.

CASE SUMMARY

The first case was a 45-year-old man who had unilateral ureteropelvic junction (UPJ) atresia and contralateral stenosis and was treated by double endoscopic surgery using an anterograde percutaneous nephroscope coupled with a rigid retrograde ureteroscope. The second case was a 12-year-old boy who received a percutaneous nephroscopy on one side and a percutaneous nephroscopy with a rigid ureteroscope on the other side due to the presence of bilateral UPJ stenosis. The third case was a 32-year-old woman with bilateral lower ureteral stricture treated using a rigid retrograde ureteroscope. Endoscopic surgeries were successfully performed on all the three patients. Varying degrees of encrustation and erosion of the urothelium were observed during the operation. The calcified layer composition analysis showed magnesium ammonium phosphate or carbonate apatite. Two patients achieved a good prognosis.

CONCLUSION

Minimally invasive endoscopic treatment for urothelial encrusted pyelo-ureteritis disease can yield better results.

Core Tip: We retrospectively summarize our clinical experience on the use of minimally invasive endoscopy in the treatment of urothelial encrusted pyelo-ureteritis disease. Since urothelial encrusted pyelo-ureteritis disease is clinically infrequent, we discuss and analyze the clinical manifestations, laboratory examination, imaging characteristics, morbidity, and treatment process of three patients with this disease. We carefully followed them for a long time and observed good therapeutic effects.
