The multistage operations may be most suitable. Bleeding is a risk in any operation. Postoperatively, a pressure dressing is often used. Transfusion, however, is uncommon. Infection is another concern but rarely occurs after hypospadias surgery.
Bladder spasms can occur for few days due to stent irritation of the bladder.
Medications help but do not eliminate spasms completely. Fistula, a leakage of urine from somewhere along the newly constructed urethra, is another risk. This risk is minimal in the simple repairs, but is significant in more extensive operations. Fistulas typically require additional surgery but in general are easily fixed with an outpatient surgical procedure. It is critical that fistula repair is not done sooner than 6 months from the time of the original operation.
