Dengue shock syndrome after percutaneous nephrolithotomy leading to hematuria and renal failure: A rare complication.

Hematuria following percutaneous nephrolithotomy (PCNL) is a dreaded complication. It necessitates blood transfusion in up to 10% of patients. It may be severe enough in <1% of patients to require angioembolization. We present a 50-year-old male who underwent PCNL for renal pelvic calculus. Since the day of the surgery, he had low-grade fever (100 degrees F) which worsened (102 degrees F) from the 2(nd) postoperative day. His preoperative urine culture was sterile. His platelet counts started dropping and NS1 antigen for dengue was positive. He also developed anemia (hemoglobin: 7g%) and platelet counts dropped to 17,000/cmm. He developed anuria on the 7(th) postoperative day, with serum creatinine rising to 7 mg%. He required two sessions of hemodialysis and urine output improved. There is a need for high index of suspicion for dengue, especially when fever and hematuria coexist in post PCNL patients......
