Occupational hazard in urolithiasis patients in Qatar: A single-center cross-sectional study.

BACKGROUND: Urolithiasis is one of the most prevalent urological diseases and is associated with a substantial economic burden. Its prevalence varies according to geographical location. Qatar is a Middle Eastern country located in the Afro-Asian Stone Belt. It has a dry and hot climate, which may predispose individuals working in these environments to form kidney stones (KSs). METHODS: A population sample of 4204 patients was categorized into five occupational classes. The frequencies and correlations of these occupations with KS formation were calculated. RESULTS: Among the total cases, 2000 presented with KSs, with the majority being of Asian descent (49%), followed by individuals of Middle Eastern descent (35.1%). Technicians accounted for 35.15% of KS cases followed by clerks (29.2%) and executives (14.6%). Among KS cases, 44% had a single stone, 30% had multiple stones, and 26% had two stones. In comparing both KS and non-KS groups, age, gender, occupation, and race were significantly associated with KS formation (p<0.05), while BMI did not show any significant correlation (p>0.05). Asian males aged 31-40, working as technicians, were significantly more prone to urolithiasis. In comparing age, BMI, and gender with stone characteristics, only age was found significantly associated with stone size (p<0.05). Occupation showed an impact on all studied stone characteristics. Clerks and technicians presented more frequently with stones within the 11-15 mm range, while executives more frequently presented with smaller stones (p<0.001). Stone density was more frequently <500 HU in workers, technicians and housewives and >500 HU in executives and clerks (p<0.001). CONCLUSIONS: Our findings revealed an elevated risk of urolithiasis among certain occupational groups, particularly technicians, who frequently work outdoors in high-temperature environments. Alternatively, the sedentary nature of clerical and executive positions can also contribute to the risk of urolithiasis.

The sclerosing Sertoli cell tumor of the testis is an extremely rare entity.

We present the case of a 31-year-old single male patient, who was admitted through emergency unit with painless hard nodule of his left testis of 6 months' duration. Ultrasound scan of the scrotum showed a fairly well-defined hypo echoic area in the left testicular parenchyma in its middle part, measuring approximately 10 × 9 mm in size. We performed left inguinal radical orchidectomy. Histopathology examination of the left testis revealed sclerosing Sertoli cell tumor (SSCT) of the testis. This is a very rare testicular tumor with very few published case reports. Systemic examination was performed to exclude systemic metastasis. SSCT is characterized by the presence and aggregates of tubules of Sertoli cells, separated by a sclerotic intercellular matrix formed by fibrotic connective tissue.
