^†Approximate period.

^#Clinical or radiological success rates.

^*Some reports did not report complications as per Clavien-Dindo grading directly; The reports were graded based on the description. Some authors included UTIs in the complications. There were no Grade-4 complications related to surgery reported in any of the studies. In many series, same patients have had complications of different grades, hence they cannot be summated.
