Luteinizing Hormone Pulse Frequency and Amplitude in Azoospermic, Oligozoospermic and Normal Fertile Men in Turkey
(Wolters Kluwer Medknow Publications, 2002) Odabas, Ö; Atilla, MK; Yilmaz, Y; Sekeroglu, MR; Sengül, E; Aydin, S
Aim: To investigate the LH pulse frequency and amplitude in azoospermic and oligozoospermic patients and to compare them with normal fertile subjects. Methods: In this controlled clinical study, 10 normal fertile male volunteers and 20 infertile patients (10 oligozoospermic and 10 azoospermic) were enrolled. Blood samples were taken every 30 minutes for 12 hours. FSH, LH and T levels were determined. LH was observed at all the blood samples, but FSH and testosterone only at the first, middle and last samples. Results: The mean LH levels were significantly different between all the groups, but there was no statistical difference in the FSH levels between the fertile and oligozoospermic groups. The mean LH levels increased from the fertile towards the azoospermic groups (P<0.01). The LH pulse amplitude and frequency were significantly different between all the 3 groups. The former increased while the latter decreased from the fertile to the azoospermic groups. The T levels were different statistically only between the fertile and the azoospermic groups. Conclusion: The more prominent is the testicular defect, the lower will be the LH pulse frequency and the higher the amplitude.
Micro-Spoon Technique in Estimation of Sperm Concentration in Rat Epididymis
(Tohoku Univ Medical Press, 2000) Odabas, Ö; Timurkan, H; Atilla, MK; Yilmaz, Y; Sengül, E; Aydin, S
Several technical procedures mere described for estimation of epididymal sperm concentration until today. In all of the described techniques, epididymal material was drawn into a micro-pipette before counting procedure. We aimed to proceed this stage without using any pipette because of the difficulty in aspirating very viscous epididymal material into a micro-pipette. For measuring epididymal material we used a 2 mu l reservoir which me named as a micro-spoon. It was filled with the epididymal material and layered in a tube with Ringer's solution of 2 mi containing sodium hyaluronate. Then, it was mixed in order to obtain 1/1000 diluted suspension. Sperm cells in this suspension were counted on a Makler chamber under a light microscope. The procedure was easy and time saving, compared to the other techniques.

New Drainage Technique in the Ureteropelvic Junction Obstructions -: Side-To Ureterocalicostomy (Or Ureterocaliceal By-Pass) Preserving Renal Pelvis and Ureteropelvic Junction
(Scandinavian University Press, 1998) Yilmaz, Y; Odabas, Ö; Aydinioglu, A; Atilla, MK; Atan, A; Aydin, S
We present a new ureterocalicostomy technique in a patient with intrarenal pelvis together with renal artery compression on the pelvis and ureteropelvic junction (UPJ). The patient had grade ii hydronephrosis in the left kidney and angulation at the ureteropelvic junction. We performed side-to-side ureterocalicostomy between the ureter and lower calyx of the kidney.
Utilising an Ileal Segment in the Posterior Urethral Replacement Procedures Using Anal Sphincter To Provide Continence in Dogs
(Tohoku Univ Medical Press, 1998) Yilmaz, Y; Aydin, M; Bakir, B; Atilla, MK; Odabas, Ö; Aydin, S
We aimed to replace an ileal segment in the place of posterior urethra using the anal sphincter as a continence mechanism. The experiment was carried on three male street dogs. In the first stage, only urethral replacement with an ileal segment was done and pulled through the anal sphincter in a male dog to see if anal sphincter would do any help for continence. A protruding stoma was created on the perineum. Perineal end of the ileal segment was sutured to the bulbous urethra in the other two male dogs to provide urethral patency in the second step of the operation. The dog in which the first operation was made gained continence on the 12th postoperative day. The other two male dogs, in which ileourethral anastomosis were made, became continent on the postoperative 12th and 15th days. No residual urine was found by catheterisation performed after urination. In controls, neither the stoma nor the anastomosis sites developed stenosis. This procedure may be applied in patients with complete incontinence who can not be corrected by any other surgical procedures, and a very good cosmetic result may be obtained.
