  ABSTRACT: This study was conducted to analyze the efficacy of photoselective vaporization of the prostate (PVP) with the use of a 980 nm diode laser for benign prostatic hyperplasia (BPH) according to postoperative period. Data were collected from 96 patients who were diagnosed with BPH and who underwent PVP with the 980 nm K2 diode laser. Postoperative parameters, including International Prostate Symptom Score (IPSS), quality of life (QoL) score, maximum urinary flow rate (Qmax), and post-void residual volume (PVR), were assessed and compared with preoperative baseline values. The mean prostate volume was 45.3±15.6 g, the mean operative time (lasing time) was 22.9±18.3 minutes, the total amount of energy was 126±84 kJ, and the Foley catheter maintenance period after PVP was 24.8±5.6 hours. At 1 month, significant improvements were noted in IPSS (11.7±6.6), QoL score (2.3±1.1), Qmax (12.7±6.1 ml/sec), and PVR (41.9±30.5 ml). After 3 months, all follow-up parameters showed significant improvements that were sustained throughout a period of 6 months after PVP. PVP using a K2 diode laser is a minimally invasive and effective surgical method for improvement of BPH and is associated with minimal morbidity.

  ABSTRACT: The number of patients waiting for kidney transplantation is incessantly increasing, but the number of cadaveric kidney transplantations or ABO-compatible donors is so insufficient that ABO-incompatible kidney transplantation is being performed as an alternative. There are overseas studies and research showing that the 5-year survival rate and 5-year graft survival rate of ABO-incompatible kidney transplantation are not much different from those of ABO-compatible kidney transplantation. However, domestic research on the subject is rare. Therefore, we report the results of 22 ABO-incompatible kidney transplantation cases performed in our hospital. This research was from 22 patients in our hospital who underwent ABO-incompatible kidney transplantation from 15 February 2007 to 20 May 2010. As yet, there have been no donor graft losses and no deaths after transplantation. The results of the two groups were analyzed by analysis of covariance of the creatinine value of the recipients at 6 months after the operation, corrected for the preoperative value in order to statistically identify whether there were differences in renal function after the operation between ABO-compatible and ABO-incompatible kidney transplantation. The results of the analysis of covariance showed no statistical difference in renal function after the operation between the two groups. Even though there were not many cases, our initial results for ABO-incompatible kidney transplantation were positive. Considering the increasing number of patients waiting for kidney transplantation, longer-term domestic research studies of ABO-incompatible kidney transplantation are necessary.
