Öğe Acute side effects of iopromide and diatrizoate in urography(Munksgaard Int Publ Ltd, 1998) Sahin, H; Bircan, MK; Akay, AF; Kuru, AFPurpose: In a prospective study, we compared the acute (0-2 h) side effects of ionic and nonionic contrast media in 767 patients undergoing intravenous urography. Material and Methods. A nonionic contrast medium (iopromide) was compared to an ionic contrast medium (diatrizoate). Results: Side effects occurred in 25 patients (7.9%) receiving iopromide and in 104 patients (23.1%) receiving diatrizoate (p<0.01). The reactions in the iopromide group were mild in 11 patients, moderate in 5, and severe in 1. The reactions were 83, 19 and 2, respectively, in the diatrizoate group. The number of reactions that required treatment was equal in the two groups (p>0.05). Conclusion: At intravenous urography, iopromide induced fewer side effects compared to diatrizoate.Öğe Comparison of laparoscopic and open ligation of the testicular vein in bilateral varicoceles(Monduzzi Editore, 1997) Sahin, H; Bircan, MK; Akay, AFWe performed bilateral varicocelectomy by infrapubic incision in 16 patients with bilateral varicocele in our clinic between November 1995 and August 1996. The results of this method were compared with laparoscopic varicocelectomy results received from the literature. Open surgery has been found more advantageous according to the type of anesthesia, duration of the operation, complications and cost-effectiveness, There is no significant difference between two methods according to the time of returning to normal activity. But, postoperative analgesic requirement in open surgery is more than that of laparoscopic varicocelectomy. It is not known completely which method is best in varicocele treatment. But, in our clinic, open surgical ligation with Kelami's incision will be prefered in bilateral varicocelectomies until a certain concensus held about this treatment.Öğe The effects of unilateral testicular torsion in rats(Monduzzi Editore, 1997) Sahin, H; Bircan, MKIn this experimental study, the effect of unilateral testicular torsion on the both testes and fertility rate was studied in adult Wistar Albino rats. Twenty fertile male Wistar Albino rats were divided into five groups. Sham operation was performed in first group. The left testicular torsion followed by detorsion and bilateral testicular fixation after 2, 4 and 6 hours were performed in 2, 3 and 4 groups, respectively. The left testicular torsion followed by left orchidectomy after 48 hours and right testicular fixation was performed in last group. Fertility was controlled after 8 weeks. We found that unilateral testicular torsion for more than 4 hours have an detrimental effect on the both testes and fertility potential of the rats.Öğe Efficacy of prilocaine-lidocaine cream in the treatment of premature ejaculation(Williams & Wilkins, 1996) Berkovitch, M; Keresteci, AG; Koren, G; Sahin, H; Bircan, MK[Abstract Not Available]Öğe Endoscopic treatment of complete posterior urethral obliteration(Monduzzi Editore, 1997) Sahin, H; Bircan, MK; Gocmen, MThe management of posterior urethral obliteration remains a surgical challenge. We performed endoscopic reconstitution of the urethra followed by temporary self-dilation in five patients with complete short posterior urethral obliteration (less than 3 cm). Average followup is 15 months (4-36 months). During follow up 4 of these patients required 1 or 2 internal urethrotomies within the first 4 to 24 months after treatment. The other fifth patient has no complication at fourth month postoperatively. One patient had impotence after the injury. Impotence continued and total incontinence developed after the endoscopic treatment. We believe that endoscopic treatment followed by temporary self-dilation could be a reasonable alternative to open urethroplasty in patients with an impassable short stricture.Öğe Huge leiomyoma of the prostate(Scandinavian University Press, 1998) Yilmaz, F; Sahin, H; Hakverdi, S; Arslan, A; Bircan, MK; Kiliç, N[Abstract Not Available]Öğe JJS application in acute symptomatic hydronephrosis in pregnancy(Elsevier Sci Ireland Ltd, 1997) Sahin, H; Bircan, MK; Yayla, M[Abstract Not Available]Öğe Reconstruction techniques in renal injury(Saudi Med J, 2005) Akay, AF; Sahin, H; Nergiz, Y; Aflay, U; Bircan, MKObjective: Kidney repair reconstruction techniques are controversial. The conventional technique is suturing, but this is usually with further loss of viable tissue as it promotes scaring. In this animal model, we investigated the parenchymal effect of different sutures and methods. Methods: We carried out this study in the year 2000 in the Animal Laboratory of Dicle University, Diyarbakir, Turkey. We used 40 New Zealand white rabbits in this study, randomized into 5 groups. We separated the left kidney from Gerota's fascia, and performed standard lacerations with incisions 5 mm deep and 10 mm in length. We performed no reconstruction procedure in group 1, and used homeostatic collagen powder in group 2. We primarily sutured the lacerations with chromic gut (4/0) in group 3, and sutured the kidney in group 4 with polyglactin (4/0). We wrapped the kidney with a polyglactin mesh in group 5. We sacrificed 2 rabbits in each group postoperatively on day 2, 15, 45 and 90, and performed left nephrectomy for histological investigation, and assessed interstitial inflammation. Results: While group 5 established the best results, the other 4 groups had similar intermediate results. The pseudocapsule was visible macroscopically in the polyglactin mesh group. We could see mononuclear cell infiltration, dilatation of tubules, atrophy of tubules, and interstitial fibrosis in all groups except group 5. Conclusion: In this animal model, we found that the most appropriate repair material for kidney surgery was polyglactin mesh.Öğe Retrospective analysis of 135 renal trauma cases(Wiley, 2004) Sahin, H; Akay, AF; Yilmaz, G; Taçyildiz, IH; Bircan, MKBackground: We review our trauma cases over the last 11 years and discuss our diagnosis and treatment modalities. Methods: One hundred and thirty-five patients with renal injuries who had been hospitalized in the Urology and General Surgery clinics of Dicle University hospital between 1990 and 2001 were reviewed retrospectively. Patients were evaluated with regard to age, sex, cause of trauma, transport time, diagnostic methods, grade of injuries, associated organ injuries, treatments and complications. Results: One hundred and forty-one renal injuries were established in 135 patients. The patients were between 5 and 65 years old; 114 (84.4%) were male and 21 (15.6%) were female. The most common cause of injuries (99 patients) was penetrating injuries. The transport time to hospital after injury was approximately H 6 min. Immediate laparotomy was performed in 95 hemodynamically unstable patients. Radiological investigations were carried out in the remaining 40 patients. Most of the injuries were grade 4 (28, 19.86%) or 5 (60, 42.55%). Isolated renal injury was established in only 22 of 135 patients. Nephrorrhaphy was performed in 45 of 141 kidneys. Twelve injured kidneys were managed conservatively. Nephrectomy was performed in 66 of 141 kidneys. The remaining injured kidneys were managed with different treatment methods. Twenty-nine (21.48%) patients were lost intraoperatively or during the early postoperative period. Conclusion: We believe that our rates of nephrectomy and mortality were high because of the long transport time, unsuitable transport type, frequent high grade and high rate of associated organ injuries.Öğe A simple method for checking J-J stent position - Reply(Blackwell Science Ltd, 1996) Bircan, MK; Islim, F[Abstract Not Available]Öğe Transurethral resection of the prostate using suprapubic drainage(Monduzzi Editore, 1997) Sahin, H; Bircan, MKIn this study, transurethral resection of the prostate was performed in 73 patients with urinary outflow obstruction during 1991 and 1996. The intermittent flow irrigation technique was performed in first 18 operations and continous flow in the remaining 55 patients. The mean resection time, urethral catheter stay time is significantly shorter in the continous flow group. There were no significant difference in hospital stay time. According to our study, the resection of the prostate is easy to perform and shorter in time, using continous suprapubic drainage. Also it is very easy for the urologists and comfortable for the patient to determine the residual urine via suprapubic catheter after the first micturition.
