Ureteropelvic Junction Obstruction with Renal Pelvic Calcification: A Case Report

Abstract

Calcification in the wall of the renal pelvis is rare. We report on a 65-year-old man with hydronephrosis secondary to ureteropelvic junction obstruction with renal pelvic calcification. Calcium deposit was found in the wall of the severely dilated renal pelvis. Pathological examination revealed a damaged and hyalinized fibrous renal pelvic wall and serum calcium level was normal. Thus, we speculated that this calcification was dystrophic. Chronic extensive dilatation with intermittent hemorrhage of the renal pelvic wall may have caused this dystrophic renal pelvic calcification.

‘Porcelain Kidney’: Case Report and Review of the Literature

“…Rarely, a similar clinical presentation of calcification in the renal pelvic wall in cases of delayed presentation of congenital ureteropelvic junction obstruction has been reported [3][4][5][6][7] . The etiopathogenesis could stem from ischemia of the renal pelvis due to chronic long-standing pressure of obstructed urine, leading to dystrophic calcification.…”

Cancer‐specific promoters for expression‐targeted gene therapy: ran, brms1 and mcm5

“…Dystrophic calcification occurs as a result of chronic inflammation or tissue necrosis. In the genitourinary tract, dystrophic calcification has been reported in upper tract tumors, renal parenchymal disease, prostatic cancer and some squamous cell carcinomas of the bladder . A feature generally associated with late‐stage necrosis of severely diseased tissues, mineralization was only found in sham‐treated bladders and was not observed in the histology of the P ran ‐RevCasp3 treated bladders.…”

Dystrophic Calcification and Stone Formation on the Entire Bladder Neck After Potassium-titanyl Phosphate Laser Vaporization for the Prostate: A Case Report

“…There have been reported cases of calcium deposition secondary to burn wounds, repeated trauma, needle sticks in the heels of neonates, thumb sucking by children, radiation and surgery (2-4). Although rarely seen in the genitourinary tract, it has been associated with schistosomiasis (5), renal and ureteral tumors (6), renal parenchymal disease (7), Churg-Strauss vasculitis (8), and polyarteritis nodosa (9). However, there have been no reports of dystrophic calcification and stones formation on the bladder neck associated with previous KTP laser vaporization of the prostate.…”
