Acute renal failure is typical in patients with renal cortical necrosis, with associated complications (eg, hyperkalemia, fluid overload). Chronic renal failure, occurring in 30-50% of patients, requires dialysis and transplantation.
The average hospital stay is 1 to 3 nights which varies depending on type of surgery and your overall condition. Duodenal switch surgery: 2 to 3 days; Gastric bypass surgery: 2 to 3 days; Gastric sleeve surgery: 2 to 3 days; Mini gastric bypass: 2 to 3 days; Gastric banding surgery (LAP-BANDÂ®): 1 day or less; Gastric Balloon: Same-day (outpatient)
Now the hard work starts. Recovery time will depend on the size of the incision made. If you had laparoscopic gastric bypass surgery performed, you will likely stay in the hospital for 2 to 3 days. If your surgery became an open procedure (bigger incision) recovery and your hospital stay may last longer. The area of the incisions will be sore in the days following surgery.
