    Background: To evaluate the results of various types of radiofrequency ablation (RFA) treatment of renal tumors in patients with excessive anesthetic and surgical risk. Materials and Methods: Data for RFA performed in in high risk patients were retrospectively evaluated. Other RFA applications in patients with no anesthetic and/or surgical risk were excluded. RFA was by ultrasound or CT guided percutaneous (USG/CT-PRFA) and retroperitoneally or transperitoneally laparoscopic (R/T-LRFA) techniques under general or local anethesia. Follow-up data of enhanced CT or MRI after 1, 3 and 6 months were analysed for twelve RFA applications. Results: The RFA applications included 4 (40%) left-sided, 5 (50%) right-sided and 1 (10%) bilaterally RFA (simultaneously 1 right and 2 left). The localizations of tumors were 2 (16.6%) upper, 5 (41.6%) mid and 5 (41.6%) lower pole. The RFA applications included 9 (75%) USG-PRFA, 1 (8.3%) CT-PRFA, 1 (8.3%) T-LRFA and 1 (8.3%) R-LRFA. The mean age was 65.3 +/- 8.5 (52-76) years. The mean tumor size was 29.6 +/- 6.08 (15-40) mm. No complications related to the RFA were encountered in any of the cases. Failure (residual tumour) was determined in 8.3% (1/12) of USG-RFA application. The success rate was thus 91.7% (11/12). Other 1st, 3rd and 6th months follow-up data revealed no residua and recurrence. Conclusions: RFA application appears to be safe as a less invasive and effective treatment modality in selected cases of small renal tumors in individuals with excessive anesthetic and also surgical risk.

    Gümüs, BH; Atesci, YZ; Ucer, O; Karatas, TC; Buyuksu, C; Nese, N; Kandiloglu, AR
    This research was conducted to evaluate the effects of a transverse vs. longitudinal incision for testicular sperm retrieval. Rats were divided into 4 groups: I: control, II: sham operation, III: longitudinal incision TSRM, IV: transverse incision TSRM. Group II (sham operation) had a dissection of left testis/spermatic cord, then closure of wound. Group III underwent dissection of left testis, then a longitudinal incision (15 mm long) of testis, which was fully opened then closed again and sutured with 5-0 Vicryl (R) sutures. Group IV underwent dissection of the left testis, opening of the testis with a transverse incision, then closure with 5-0 Vicryl (R). The seminiferous tubule diameter was 0.118-0.224 mm in all groups. inflammation and abscess formation occurred in one testis each in the sham and longitudinal incision groups, and in two testes in the transverse incision group. There were no differences in histopathology or scoring between the longitudinal and the transverse incision.
