Objective: Physiological outcomes in patients of cloacal exstrophy are governed primarily by neurological innervation and detrusor histomorphology. An evaluation of the bladder plate histomorphology for the presence of neural elements, collagen fibres and smooth muscle components was done and correlation attempted with detrusor physiology. Methods: From three cases of cloacal exstrophy, full th...

Chromophobe renal cell carcinoma (ChRCC) is a subtype of renal cell carcinoma (RCC). ChRCC is diagnosed mainly in 6th decade of life. An incidence of ChRCC is similar in both men and woman. Eighty six percent of ChRCCs cases are diagnosed in stage 1 or 2. Prognosis of ChRCC is better than in other types of RCC. Five- and 10-year disease free survival (DFS) for ChRCC was 83.9% and 77.9%, respect...

MATERIALS AND METHODS Twenty cases of PA, 20 cases of AdCC and 10 cases of PLGA were retrieved from record files along wi...

Background. Placenta is a subject of interest to wide range scientists because it rich in stem cells and their precursors. A cell that has the ability self-repair can differentiate into offspring (daughter cells) one or more germ layers. In recent years, have obtained new data regenerative potential. However, only isolated publications about placental are available. Therefore, our studies impor...
