ABSTRACT
Objective: To examine the effectiveness of preoperative urethral sterilisation with chlorhexidine gel in rendering the urethra as sterile as the skin of the genital area, with the skin sterilised as per the International Society for Sexual Medicine guidelines for penile prosthesis implantation. Patients and methods: A total of 111 male patients undergoing sterile andrological surgical procedures were divided into a control group (N = 61) and a chlorhexidine gel group (N = 50). Patients in the chlorhexidine group received urethral instillation with 6 mL of chlorhexidine preoperatively and on table. Patients from both groups received on-table skin preparation using povidone iodine and chlorhexidine povidone iodine. At the end of surgery, swabs were obtained from urethra and the penile skin. Skin and urethral swabs were compared for bacterial colonisation by culture and sensitivity. Results: Of the 111 patients, 16 had urethral colonisation and 10 had skin contamination, and they were all in the control group. The most common organism detected in both the urethral and skin samples was coagulase-negative Staphylococcus aureus. Urethral colonisation was significantly greater in the control group compared to the chlorhexidine group, at 16/61 vs 0/50 (P = 0.001). Similarly, skin colonisation was significantly greater in the control group compared to the chlorhexidine group, at 10/61 vs 0/50, (P = 0.002). Conclusion: Chlorhexidine gel is a powerful sterilising agent that will render the urethra sterile.
ABSTRACT
Gynecomastia is defined as a palpable enlargement of the male breast, secondary to an increase in the glandular and stromal breast tissue. Gynecomastia is encountered in up to 80% of Klinefelter syndrome cases. The pathophysiology involves testosterone/estrogen imbalance. This review article will further explore the pathophysiology of gynecomastia along with the different lines of management.
