prevalence of pathological types of malignant renal neoplasms at King Abdul-Aziz University Hospital

ABSTRACT

The aim of this retrospective study is to estimate the prevalence of renal adult epithelial tumors as well as Wilms' tumor at King Abdul-Aziz University Hospital [KAAUH], Jeddah, Kingdom of Saudi Arabia [KSA], highlighting some of their pathological aspects and comparing our findings with other published data in the literature. The study included 74 cases of renal tumors which were examined in the department of Histopathology at KAAUH, Jeddah, KSA, from January 1995 to December 2005. The tumors were classified and the histopathological characteristics of each tumor were studied, statistically analyzed and compared with age and gender of the patients. All retrieved cases sent to histopathology department at KAAUH, Jeddah, as renal mass or tumor were reevaluated. The cases were grouped into four main categories; Renal call carcinoma [41 cases], Wilms tumor [19 cases], Urothelial carcinoma of the renal pelvis [9 cases] and a miscellaneous group which did not fall into the previous categories [5 cases]. Despite the narrow fraction of our studied cases, this study could help in giving insight that the prevalence of renal neoplasms at KAAUH is approaching that internationally documented in literature. Nevertheless, a broader community based study in Jeddah or even the whole kingdom would be helpful
