Extremely rare catastrophic complications such as necrosis of the glans, urinary retention and bladder rupture have been reported with the use of the Plastibell device, as a result of retained parts, particularly if a bell of the wrong size is used. The Plastibell should only be considered in areas where follow-up is both reliable and easily available. The Plastibell is a disposable device, whereas the Mogen and Gomco clamps are reusable. The choice between the different techniques may depend on the cost of the Plastibell, the need to sterilize the Mogen and Gomco clamps, patient age, access to follow-up, carer reliability and the possible need for suturing skills.
