Oliguria in the early postoperative phase after renal transplantation has many causes with overlapping presentations. Page kidney refers to external compression of the kidney by a hematoma, urinoma or tumor, leading to parenchymal hypoperfusion, unexplained hypertension (HTN), or frank acute renal failure. About 100 cases of Page kidney are reported; mostly after kidney biopsy. After the analysis of records, we identified four cases of acute Page kidney posttransplant, akin to a compartment syndrome. All biochemical, laboratory, and clinical parameters were recorded. Cases occurred within two to three weeks of transplant, with different causes. Clinical presentation was sudden, with HTN, raised serum creatinine and perigraft swelling in all. Rejection co-existed Page kidney in two cases, while tacrolimus had to be potentiated with diltiazem in one case. Serial parameters such as increased resistive index (>0.7), perigraft collection, and absent diastolic flow with normal peak systolic velocity were consistent with diagnosis. Two were caused by lymphoceles, more than 3 L. Both were managed by laparoscopic fenestration surgery; probably the first such instance for Page kidney. Two patients had postoperative hematoma; in one case, it followed early percutaneous angiographic stenting and "leakage" from the transplant artery, only the second such report. A high index of suspicion required for diagnosis; after excluding rejection and pre/postrenal causes, aggressive early management is the key for graft salvage.
