Screen for lynch syndrome in utic if
Based on this association, it has been suggested
that patients with UTUC should be evaluated for
Lynch syndrome if they
(1) are younger than 60 years of age;
(2) have a family history of UTUC, colon cancer
diagnosed before age 60 years, or endometrial
carcinoma; or
(3) have a personal history of colon or
endometrial cancer

Premalignant lesions
The 2004 World Health Organization classification
system for urothelial neoplasia classifies pre-
malignant lesions as urothelial hyperplasia (flat
and papillary), reactive atypia, urothelial atypia
of unknown significance (AUS), urothelial
dysplasia, and low-grade intraurothelial neoplasic
Metaplasia is benign.

Bladder sparing feasible when?
tumor presentations associated with successful
bladder-sparing therapy include:
solitary T2 or early T3 tumors(typically <6 cm in
size),
no tumor-associated hydronephrosis,
tumors allowing a visibly complete TURBT,
invasive tumors not associated with extensive
carcinoma in situ, and
urothelial carcinoma histology
