Objectives: We propose a surgical correction of the penile curvature applying a technique based on the 16-dot plication technique modified by burying the knots in a shallow trough of incised tunica. We entitle this modification the “Kiel Knots”. Material and methods: 20 patients with a penile deviation, average age 36.8 years (24 - 52) were operated. Follow-up time was 26 months. In 8 patients the deviation was congenital, in 12 patients it was an acquired deviation. The deviation was >30? in all patients. Surgical technique: A circumcising incision was made and the penis was degloved. Buck’s fascia was incised exposing the tunica albuginea opposite the curvature. 8 dots were marked bilaterally on the tunica albugineaand a5 mmincision along the marks was made without cutting into the Corpus cavernosum. Instead of plicating with one suture for 4 dots, our modification uses one suture for two dots with the knot buried in a shallow trough created by a scalpel. Results: The average operation time was 64 minutes. We observed a loss of penile length in 30% of the patients (0.5 - 1 cm). There were no problems with erectile function. In a follow-up of 2 years, 90% of the patients remained without recurrence of deviation. None of patients reported problems with the suture knots. Conclusion: Our technique achieves penile straightening with minimal loss of length and no erectile dysfunction.
Ethylenediaminetetraacetic acid (EDTA) is a chelating agent that has been used for decontamination purposes in nuclear industry. The presence of EDTA in decontamination wastes can cause complexation of the cations resulting into interferences in their removal by various treatment processes such as chemical precipitation, ion exchange etc. Further, it might also impart elevated leachability of cationic contaminants from the conditioned wastes immobilized in cement or other matrices and can negatively influence the quality of the final form of waste. In the present study, kinetics of degradation of EDTA (20,000 mg/l) by employing either Photo-Fenton process using UV (15 W λmax = 253.7 nm) or Sono-Fenton process using ultrasound at 130 KHz or simultaneous Sono-Photo Fenton process has been investigated. EDTA is effectively degraded by the synergistic effect of both Photo Fenton and Sono Fenton process. All the above mentioned processes were found to follow a first order kinetics reaction. From the observed pH changes during the oxidation processes, it can be concluded that there is a loss of chelating ability of EDTA. Formation of amides was con- firmed during the degradation processes.
