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 Changing trends in the management of iatrogenic ureteral injuries(Williams & Wilkins, 1996) Bircan, K; Korkmaz, K; Sahin, H[Abstract Not Available]Öğe Characteristics of traumatic spinal cord injuries in south-eastern Anatolia, Turkey: a comparative approach to 10 years' experience(Lippincott Williams & Wilkins, 2005) Gur, A; Kemaloglu, MS; Cevik, R; Sarac, AJ; Nas, K; Kapukaya, A; Sahin, HThe purpose of this study was to determine the demographic and epidemiological characteristics of traumatic spinal cord-injured patients. The hospital records of 539 patients (416 men, 123 women) with spinal cord injuries (SCIs) admitted to four hospitals that were major referral centers for trauma in the south-eastern region of Turkey from 1990 to 1999 were reviewed retrospectively. The patients with SCI were investigated for two periods; the first period covered patients admitted between 1990 and 1994 during which time an influx of people from rural to urban areas occurred and firearm injuries were common. In the second period (1995-1999) the influx of people declined and firearm injuries were reduced. The most common causes of injuries were road traffic accidents (200, 37.12%), followed by falls (172, 31.90%) and bullet wounds (115, 21.34%). In the first period, incomplete paraplegia was encountered more often than in the second period (P < 0.001).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 Delivery of dead fetus from inside urinary bladder with uterine perforation: Case report and review of literature(Elsevier Science Inc, 2005) Atug, F; Akay, F; Aflay, U; Sahin, H; Yalinkaya, AThe incidence of cesarean sections has increased radically worldwide in the second half of the 20th century, especially in developing countries. Generally, a trial of labor after a cesarean section is safely accepted. However, a trial of labor may lead to serious complications, including unpredicted ones, such as rupture of the uterus during labor with concomitant injury to the bladder. We report the delivery of a dead fetus through the urinary bladder during labor.

Material and Methods: A total of 43 patients (30 with renal and 13 with ureteral stones) underwent color Doppler examination before and 30 min and 3 h after ESWL. Seventeen patients with renal and nine with ureteral stones underwent Doppler examination 2 weeks later. Measurements were made near the stones (nearby region), at least 2 cm from the stones (remote region) and in the contralateral kidney for renal stones, and in the ipsilateral and contralateral kidneys for ureteral stones. Results: In patients with renal stones, the RI was increased 30 min and 3 h after ESWL in the nearby and remote regions, and more markedly in the former. In the contralateral kidney, there was an increase in RI only at 3 h, which was less than that in the ipsilateral kidney. The RI at 2 weeks post-ESWL in the nearby region and contralateral kidney did not differ from the pre-ESWL values. ESWL performed for ureteral stones caused no increase in RI in the ipsilateral kidney. Conclusion: Patients with renal stones had a temporary increase in RI in the hours following ESWL in both the ipsilateral and contralateral kidneys, which was highest in the region near the stones and lowest in the contralateral kidney. Two weeks later, the RI in both areas had returned to pre-ESWL levels.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 Expression of p53 oncoprotein and bcl-2 in renal cell carcinoma(Saudi Med J, 2005) Uzunlar, AK; Sahin, H; Yilmaz, F; Ozekinci, SObjective: The aim of the present study was to investigate the significance of p53 and bcl-2 as prognostic factors among others in renal cell carcinoma patients. Methods: We evaluated the stages, histological grades, tumor diameters, cellular patterns and the presence of mutant p53 protein and bcl-2 overexpression in 57 cases of renal cell carcinoma (RCC). Kaplan-Meier and log-rank tests estimated the survival function of each parameter. The study was carried out in the Department of Pathology and the Department of Urology, Faculty of Medicine, Dicle University Hospital, Diyarbakir, Turkey, in 2003. Results: The p53 mutation was 35% and bcl-2 overexpression incidence was 89.4% in the RCC cases included in the study. The 5-year disease specific survival rates of mutant p53 positive was 46.6% and p53 negative cases were 83.3%, (p=0.0063). There was no pathological parameter associated in bcl-2, and it has no prognostic significance. Conclusion: The tumor stage, grade, diameter and p53 mutations affect the survival of RCC cases. The bcl-2 staining did not play any role to estimate patients at high risk of the disease progression.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 A new treatment for clot retention: Intravesical streptokinase instillation(Williams & Wilkins, 1996) Korkmaz, K; Sahin, H; Islim, F; Bircan, Z; Inci, I[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 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.Öğe Urinary system stone disease is endemic in Southeastern Anatolia(Scandinavian University Press, 1997) Sahin, H; Bircan, Z[Abstract Not Available]
