Hydrocalyx: Uncommon Complication of Percutaneous Nephrolithotomy
MetadataShow full item record
The success rate of percutaneous nephrolithotomy (PNL) is about 90%, but overall complications of this surgery have been reported in up to 83% cases. The complications are graded using Clavien classification system from grade 1 to 5. Grade 1 needs simple treatments without surgical, endoscopic, and radiologic interventions like antiemetics, antipyretics, and analgesics. Grade 5 denotes death of the patient. Calyx neck stricture is grade 3b complication with an incidence of 0.1%. In this study, a case of hydrocalyx, which is very rare complication after PNL, is presented. To the best of the authors' knowledge, there is no hydrocalyx case reported after PNL in the literature.
