Suprapubic Endoscopy: a Percutaneous Approach

We have assessed whether suprapubic endoscopic surgery can be helpful in situations where transurethral access is inadequate, difficult or likely to be associated with urethral damage and have applied a modified version of the well known techniques for creating and dilating a track for percutaneous renal access to the bladder. This method has been used in a series of clinical cases and in certain experimental studies. Assessment of the techniques has allowed their modification and the development of a specially designed access cannula--the St Peter's Hospital cannula.
