children, kidney\'s cysts, Bosniak\'s classification


Introduction. In children cystic lesions of the kidney vary as to their morphology and oncological classification. Simple renal cysts are rare in pediatric population, but in view of their non-uniform clinical picture, a possibility of mistaking for malignant lesions and associated symptoms, such cysts pose a serious diagnostic and therapeutic problem. The classification of Bośniak was to be helpful in resolving these issues.
Material and method. The analysis included seven patients treated for simple renal cysts between 1986-98. The most common presenting symptoms were abdominal pain, erythrocyturia, recurrent urinary tract infections and hypertension. In six children the lesions were classified as Bośniak type I and one as Bośniak type III. In six patients the cysts were surgically removed, while the seventh, whose the lesion was below 2.5 cm in size, was followed-up.
Results. All the patients did well postoperatively and no complications were noted. The cyst associated symptoms resolved. Hi-stopathology confirmed simple renal cysts in all the children.
Conclusions. In absence of conclusive imaging, cytological and immunological diagnostic methods when dealing with a patient with a renal cyst the surgeon is often inclined to undertake surgical intervention. Videoscopic procedures seem to combine the advantages of open surgery without the disadvantages of the classic procedures.
