[A comparative study of three different circumcision devices for redundant prepuce and phimosis].

OBJECTIVE

To compare the clinical effects of disposable titanium nail circumcision stapler (TNCS), one-off circumcision stapler (Shang Ring) and disposable double-handle circumcision suture device (DHCSD) in the treatment of redundant prepuce and phimosis.

METHODS

We reviewed the clinical data on 150 cases of redundant prepuce or phimosis treated with the TNCS (n = 50), DHCSD (n = 50) or Shang Ring (n = 50) from September 2018 to July 2020. We compared the operation time, intraoperative blood loss, wound healing time, Visual Analogue Scale (VAS) scores during and at 1 hour and 7 days after operation, postoperative complications and the patients' satisfaction with postoperative penile appearance among the three groups.

RESULTS

The operation time was significantly longer (P < 0.05) but the wound healing time remarkably shorter (P < 0.05) in the TNCS and DHCSD groups than in the Shang Ring group. The intraoperative blood loss was markedly less in the TNCS and Shang Ring groups than in the DHCSD group (P < 0.05). No statistically significant difference was observed in the patients' satisfaction with postoperative penile appearance among the three groups (P > 0.05). The VAS scores during and at 1 hour and 7 days after operation and the incidence rate of postoperative complications were significantly higher in the Shang Ring and DHCSD groups than in the TNCS group (P < 0.05).

CONCLUSIONS

The disposable titanium nail circumcision stapler is superior to disposable double-handle circumcision suture device and Shang Ring in the treatment of redundant prepuce and phimosis and deserves clinical promotion and application.?
