Neobladder stone
Updates to Case Attributes
When a patient with a history of transitional cell tumor and ileal neobladder presents with hematuria, it is important to know that there are complications of hematuria in the short and long term.
-
As parametersFactors to take into account we must know that:
-
Thethe risk of forming new stones at five years is63.3~65%. -
Thethe time of appearance of the stones is variable and can range from 6 months to several years later.
As etiopathogenic factors we find
Pathogenesis and aetiology includes:
- Main factor: urinary stasis.
- The continuous secretory and absorptive function of the ileum and colon that contributes to the origin of lithiasis formation.
- Metabolic acidosis: loss of bicarbonate and reabsorption of urine solutes.

Abdominal CT shows a slight dilatation of the excretory system on the right side, with distal lithiasisstone immediately prior to the insertion of the neobladder, which also presents a greatlarger internal lithiasisstone.
