Purpose: We describe a simple technique for achieving radial and equally spaced sutures by novice corneal surgeon in cases of large penetrating keratoplasties. Method: A simple mathematical equation was derived for precise calculation of spacing between interrupted sutures in large grafts ( n = 50). The ubiquitous and easily available Castroviejo calipers were used to mark the donor cornea according to the derived formula. Interrupted sutures were passed over the pre-marked points and tied. Radiality was assessed in the post-operative period. Results: A total of 50 eyes undergoing therapeutic keratoplasty with graft size between 9 and 12 mm were enrolled. Equally spaced and radially aligned sutures were achieved in all cases postoperatively with watertight apposition of the graft host junction using our simple technique. Conclusion: The Castroviejo caliper can be effectively used for equidistant spacing of interrupted sutures in large therapeutic grafts by a novice surgeon thereby simplifying the procedure and reducing the surgical time.

Positive Effect

This article summarizes our clinical treatment results for various stages of corneal sequestrum in 24 cats using mesenchymal stem cell secretome (cytokines / growth factors). Our results show that the regenerative drug used in the study had a positive effect on the quality and speed of the corneal regeneration and effectively reduced inflammation during the post-operative period, which contributed to the lack of any rejection of donor cornea.

Post Operative Period

SummaryIn the post-operative period the levels of factor I, VII—X, VIII, IX and X as well as the platelets are increased. In the immediate post-operative period there is a decrease in the levels of factors II and XI. The significance of these changes in relation to venous thrombosis is discussed.

Objective: To assess the success of BMG urethroplasty in long segment anterior urethral stricture. Method: From January 2014 to December 2015, twenty male patients with long anterior segment urethral stricture were managed by BMG urethroplasty. After voiding trial they were followed up at 3 month with Uroflowmetry, RGU & MCU and PVR measurement by USG. Patients were further followed up with Uroflowmetry and PVR at 6 months interval.Successful outcome was defined as normal voiding with a maximum flow rate >15ml /sec and PVR<50 ml with consideration of maximum one attempt of OIU after catheter removal. Results: Mean stricture length was 5.2 cm (range 3-9 cm) and mean follow-up was 15.55 months (range 6-23 months). Only two patients developed stricture at proximal anastomotic site during follow-up. One of them voided normally after single attempt of OIU. Other one required second attempt of OIU and was considered as failure (5%). Conclusion: BMG urethroplasty is a simple technique with good surgical outcome. Bangladesh Journal of Urology, Vol. 19, No. 2, July 2016 p.64-68
