Laparoscopic Management of a Renal Hydatid Cyst Masquerading as Simple Renal Cyst.

Hydatid cyst is a parasitic disease caused by the tapeworm Echinococcus granulosus. Hydatid cyst disease mostly involves the liver and the lung, while renal involvement is rare. Hydatid disease may present in unusual ways and lead to diagnostic diffi culty and management problems. A high index of suspicion for hydatid disease should be maintained while evaluating complex cystic renal masses. Herein we present an interesting case who was diagnosed to have a simple renal cyst on contrast-enhanced computed tomogram, which turned out to be a renal hydatid cyst. Despite modern imaging methods, isolated renal hydatid disease might still cause diagnostic dilemma and hydatid cysts can be found in unusual localization. Th is case was managed laparoscopically.

Evaluation of acquired cystic kidney disease in patients on hemodialysis with ultrasonography

Acquired cystic kidney disease [ACKD] occurs in patients with prolonged uremia, and early detection is important, because clinically significant complications, especially renal cell carcinoma, are associated with ACKD. In a cross-sectional study, we evaluated our patients on hemodialysis, in Ahvaz, Iran, using ultrasonography. The criteria for the diagnosis of ACKD were the presence of at least 4 bilateral renal cysts in patients with noncystic primary kidney diseases as the leading cause of kidney failure. A total of 148 patients [95 men and 53 women] were included in the study. The prevalence of ACKD was 20.3% [18.9% in men and 22.6% in women]. The mean age in patients with and without ACKD was 60.6 +/- 16.8 years and 53.6 +/- 14.9 years, and the mean hemodialysis duration was 44.2 +/- 18.7 months and 34.3 +/- 23.5 months, respectively. There were no significant differences in the frequency of ACKD in the men and the women [P = .59] and in the etiology of end-stage renal disease [P = .64]. It was significantly more likely to see ACKD in patients with a history of 3 years or longer being on hemodialysis than in those with a shorter dialysis duration [P = .001]. Acquired cystic kidney disease is common in patients on hemodialysis, and we suggest that renal ultrasonography be performed in patients with 3 years or more history of being on renal replacement therapy

Detección de quistes renales por ultrasonido en 1064 pacientes / Ultrasonic detection of renal cysts in 1064 patients

El propósito del estudio fue explorar por medio de ultrasonido ambos riñones para determinar la frecuencia de quistes renales, independientemente de su etiología. Este fue un estudio prospectivo y observacional practicado en 1064 pacientes, 105 varones y 959 mujeres, que acudieron al departamento de radiodiagnóstico por diversos motivos. Se identificaron quistes renales en 24 pacientes (2.2 por ciento); de ellos, siete (0.6 por ciento) eran del sexo masculino y 17 (1.6 por ciento) del femenino. Del total de los pacientes con quistes, 17 se encontraban por encima del quinto decenio de la vida (70.8 por ciento). Se concluye que los quistes renales tienen una frecuencia elevada en pacientes que se encuentran por encima del quinto decenio de la vida. La mayoría tienen un curso asintomático y constituyen un hallazgo de exploración. Los pacientes sintomáticos fueron los que tenían quistes múltiples unilaterales o bilaterales
