The effect of intravesical cocktail therapy combined with low-dose amitriptyline on primary bladder pain syndrome.

INTRODUCTION AND HYPOTHESIS: We compared the effectiveness of intravesical combination treatment and intravesical treatment plus low-dose amitriptyline in patients with primary bladder pain syndrome (PBPS). METHODS: A total of 53 patients were included in the study. Demographic data, voiding frequency, nocturia, visual analog scale (VAS) scores, validated O'Leary-Sant IC Symptom Index (ICSI), and IC Problem Index (ICPI) scores and scores on the Short Form-36 (SF-36) questionnaire were collected from the patients at the beginning of the treatment, and at the 6th week and 6th month of the treatment. The patients were divided into two groups. Group 1 received intravesical treatment for 6 weeks. Group 2 received intravesical treatment plus amitriptyline at a dosage of 10 mg/day. RESULTS: The frequencies of voiding and VAS scores were significantly improved in groups 1 and 2 at the 6th week compared with pretreatment (in group 1 p < 0.001, p < 0.001, and in group 2 p < 0.001, p < 0.001 respectively). The median ICSI and ICPI scores also significantly decreased in groups 1 and 2 (in group 1 p < 0.001, p < 0.001, and in group 2 p < 0.001, p < 0.001 respectively). Scores on the dimensions of the SF-36 questionnaire were significantly improved in both groups. There was no significant change in terms of VAS, nocturia, ICSI or ICPI scores when comparing the 6th week and 6th month results in groups 1 and 2 (all p > 0.05). Only role functioning/emotional achieved a significant improvement in group 2 (p = 0.007). CONCLUSIONS: Intravesical combination therapies are effective in PBPS treatment. Adding low-dose amitriptyline to intravesical therapy in patients with PBPS improves emotional status.

Muslim mothers mainly saw circumcision in terms of religion or tradition but wanted it to be carried out medical professionals.

AIM: This study assessed the relationship between the education level of Muslim Turkish mothers whose sons had been circumcised and their views on circumcision. METHODS: Interviews based on 20 close-ended questions were carried out in the Çukurova region of southern Turkey between June 2015 and September 2016. The participants were 1497 Muslim Turkish mothers whose sons had been circumcised and who were recruited using convenience sampling in schools, hospitals and public spaces. RESULTS: Most (82%) of the mothers saw circumcision as a religious and traditional requirement, 64% mentioned the health benefits and 48% mentioned cosmetic appearance. The majority (80%) were performed by health organisations, with two-thirds (66%) expressing this preference. Most circumcisions were at school age (38%), which was about 6 years of age plus at the time of the study, and there were no complications in 79% of cases. Higher education levels were associated with views that circumcision was an important surgical procedure, it decreased the risk of urinary tract infections, it should be performed in hospitals and the foreskin did not prevent sexual intercourse. CONCLUSION: Circumcision was mainly seen as a religious and traditional ritual, and more highly educated Turkish Muslim mothers were better informed about the health aspects.

Is urotherapy alone as effective as a combination of urotherapy and biofeedback in children with dysfunctional voiding?

OBJECTIVE: To compare standard urotherapy with a combination of urotherapy and biofeedback sessions and to determine the changes that these therapies promote in children with dysfunctional voiding. PATIENTS AND METHODS: The data of 45 patients who participated in the study from January 2010 to March 2013 were evaluated. All patients underwent urinary system ultrasonography to determine post-void residual urine volumes and urinary system anomalies. All patients were diagnosed using uroflowmetry - electromyography (EMG). The flow pattern, maximum flow rate, and urethral sphincter activity were evaluated in all patients using uroflowmetry - EMG. Each patient underwent standard urotherapy, and the results were recorded. Subsequently, biofeedback sessions were added for all patients, and the changes in the results were recorded and statistically compared. RESULTS: A total of forty - five patients were included, of which 34 were female and 11 were male and the average age of the patients was 8.4 ± 2.44 years (range: 5 - 15 years). After the standard urotherapy plus biofeedback sessions, the post-void residual urine volumes, incontinence rates and infection rates of patients were significantly lower than those with the standard urotherapy (p < 0.05). A statistically significant improvement in voiding symptoms was observed after the addition of biofeedback sessions to the standard urotherapy compared with the standard urotherapy alone (p < 0.05). CONCLUSIONS: Our study showed that a combination of urotherapy and biofeedback was more effective in decreasing urinary incontinence rates, infection rates and post - void residual urine volumes in children with dysfunctional voiding than standard urotherapy alone, and it also showed that this combination therapy corrected voiding patterns significantly and objectively.

Six arms mesh implant application with organ-preserving in a young patient with total pelvic organ prolapse.

Pelvic Organ Prolapse (POP) is defined as the prolapse of the pelvic organs toward or through the vaginal opening as a result of the weakening of the combination of nerves, muscles and fascia, which normally protect and support the physical position of pelvic organs. In this case report, the 30-year old patient who applied with the pelvic prolapse through the vaginal opening was treated with Sacro Uterine Ligamentopexy and anterior 6 arms mesh implant, without applying hysterectomy. In the short follow-up period of three months, both anatomic improvement and positive developments in sexual and social life have been recorded in the patient's life. In conclusion, we determined that six arms mesh implant organ preserving approach is functional, safe and effective for young women at reproductive age.

After a urological laparoscopic training programme, which laparoscopic method is safer and more feasible in the management of proximal ureteral stones: Transperitoneal or retroperitoneal?

OBJECTIVE: To compare the results of the management of the first 25 transperitoneal laparoscopic ureterolithotomies with the first 25 retroperitoneal laparoscopic ureterolithotomies performed by two surgeons who had just completed a laparoscopic training programme. METHODS: The retrospective study was conducted at Adana Numune Teaching and Research Hospital and comprised retroperitoneal laparoscopic ureterolithotomies and transperitoneal laparoscopic ureterolithotomies performed by two different surgeons on patients with proximal ureteral stones between November 2011 and March 2013. The transperitoneal and retroperitoneal procedures were categorised as Groups A and B, respectively. Patients in Group A were operated on by the same surgeon (DA) and those in Group B were operated on by the other surgeon (FK). Groups were compared according to operative time, duration of drainage and urethral catheter, hospital stay, stone size, surgical success and complications. RESULTS: There were 50 patients in the study; 25(50%) in each of the two groups. Success rates in Group A and B were 21(84%) and 20(80%), respectively (p>0.05). Complications were seen in 8(32%) and 11(44%) patients in Group A and B, respectively (p>0.05). CONCLUSIONS: The transperitoneal approach was more advantageous than the retroperitoneal approach for less-experienced surgeons because it provided a wider operating field, a more familiar anatomy and more convenient suturing.

Epidemiological characteristics of Fournier's gangrene: a report of 71 patients.

INTRODUCTION: To identify the predisposing factors, etiological and clinical characteristics as well as the Fournier's gangrene (FG) severity index (FGSI) in the outcomes of patients with FG. MATERIALS AND METHODS: The data from 71 patients diagnosed with FG in a period of 17 years were retrospectively reviewed for the age of the patient, their history, predisposing factors, etiology, prodromal symptoms, FGSI, culture results, hospitalization period, surgical interventions, responses to the therapy and complications. RESULTS: All of the patients were Caucasian males, and the mean age was 61.3 (range 36-92) years. The mean duration from the onset of symptoms to surgery was 7.5 days. The mean hospitalization time was 27.4 days and the most common etiological factor for FG was a perineal abscess. The overall mortality rate was 29.6%. The relationship between the number of predisposing factors and mortality rates in patients with FG was the most statistically significant parameter (p = 0.001). CONCLUSIONS: Multiple predisposing factors predict a poor prognosis and correlate significantly with mortality. Extension of the disease and the FGSI score were not predictive of outcome. The most essential intervention for stopping the rapidly progressing infectious process of FG consists of early recognition of the disease, proper management of the predisposing factors and aggressive surgical debridement. Such an intervention can improve clinical outcomes.

Is there any predictive value of the ratio of the upper to the lower diameter of the ureter for ureteral stone impaction?

BACKGROUND: We aimed to determine if the ratio of the upper to the lower diameter of the ureter could have any predictive value for ureteral stone impaction. MATERIALS AND METHODS: Patients who had a solitary unilateral ureteric stone, determined by noncontrast computerized tomography, were assessed if they had undergone ureteroscopic lithotripsy. A total of 111 patients, 84 males (76%), and 27 females (24%), were recruited to the study. Demographic data of the patients and preoperative radiological parameters based on noncontrast computerized tomography were recorded. The impaction status was also assessed during the operation. RESULTS: Of the 111 patients, ureteral stones in 63 (57%) patients were determined to be impacted, and ureteral stones in 48 (43%) were nonimpacted. Impacted stones were more common in older patients, female patients, and patients with an American Society of Anesthesiologists score of 2. CONCLUSIONS: Significant relationships were found between the impaction status and transverse stone length, longest stone length, upper diameter of the ureter, ratio (upper diameter of the ureter/lower diameter of the ureter), and anteroposterior diameter of the pelvis. These parameters were higher in patients with impacted stones.

Is the Homocysteine Level a Good Predictive Marker for Evaluating Kidney Function in Patients After Percutaneous Nephrolithotomy.

PURPOSE: The purpose of this study is to evaluate the preoperative, early and late postoperative homocysteine levels and its relationship with kidney function in patients after undergoing percutaneous nephrolithotomy (PNL). MATERIALS AND METHODS: Twenty-three patients with kidney stones underwent PNL and blood samples were taken preoperatively as well as at 48 hours and three months after the operation. The homocysteine level was determined by high pressure liquid chromatography and the fluorometric method in blood samples with ethylenediaminetetraaceticacid. The Cockcroft - Gault formula was used to calculate the glomerular filtration rate (GFR). Non-contrast computed tomography was performed for all patients before surgery. Stone burden was calculated asthe sum of the area of each stone in mm2. RESULTS: Fourteen male (60.9%) and nine female (39.1%) patients were recruited for this study, and the median age was 44.3 ± 15.17 (20 - 71) years. There were no statistically significant differences between the preoperative homocysteine level and the level at 48 hours post-operation (P = .460). However, the homocysteine level three months after the operation was significantly lower than the preoperative and 48 hour levels (P = .001 and P = .003, respectively). CONCLUSION: Renal function, which deteriorated after the PNL procedure, was preserved or improved over time. Homocysteine may be a sensitive indicator to assess the change in renal function pre-and post-PNL.

Detection of CYP1A1 and GSTP1 gene polymorphisms in bladder cancer patients in a Turkish population using a polymerase chain reaction-restriction fragment length polymorphism method.

OBJECTIVE: Understanding genetic polymorphisms might facilitate the analysis of differences between individuals in their susceptibility to developing cancers as a result of environmental carcinogens. Skin, lung, colon and bladder cancers emerge from biological defects in GSTM1, GSTT1 and GSTP1 gene expressions. In this study, we aimed to investigate whether there was an association between CYP1A1 and GSTP1 gene polymorphisms and bladder cancer in a Turkish population. MATERIAL AND METHODS: Blood samples were collected from 120 individuals (60 patients with bladder cancer and 60 healthy individuals), and their DNAs were isolated. A polymerase chain reaction-restriction fragment length polymorphism (PCR - RFLP) method was used to detect the frequencies of CYP1A1 NM_000499.3: c.*1189T > C and GSTP1 NM_000852.3: c.313A > G polymorphisms in bladder cancer patients. RESULTS: The frequency of the CYP1A1: c.*1189 TC genotype and C allele were significantly different between bladder cancer patients and healthy individuals (p=0.001 and p=0.005, respectively). However, there was no significant difference for the GSTP1: c.313 AG genotype or G allele between both study groups (p=0.699 and p=0.360, respectively). CONCLUSION: A polymorphic site of the CYP1A1 gene might be involved in the development of bladder cancer. However, the investigated GSTP1 polymorphic site did not represent an important risk factor for the development of bladder cancer in a Turkish population.

Beneficial effects of rolipram, a phosphodiesterase 4 specific inhibitor, on testicular torsion-detorsion injury in rats.

INTRODUCTION: The aim of the study is to investigate the effect of Rolipram, a selective phosphodiesterase 4 inhibitor, on testicular torsion - detorsion injury. METHODS: Sixty young male rats were divided into five groups. In each group, the right testes of six rats were removed four hours after detorsion for biochemical analysis, and the right testes of the remaining six rats were removed 24 h after detorsion for pathological analysis. In group 1 (sham-operated) right orchiectomy was performed without torsion, and right testes were sent to the laboratory for biochemical and pathologic analyses. In group 2 (control) torsion was applied to the right testes for 60 min, and detorsion was performed without the administration of Rolipram. In group 3 torsion was applied to the right testes for 60 min. 1 mg/kg Rolipram was administered 30 min before detorsion. In group 4 torsion was applied to the right testes for 60 min, and 1 mg/kg Rolipram was administered during detorsion. In group 5 torsion was applied to the right testes for 60 min. 1 mg/kg Rolipram was administered 30 min after detorsion. The malondialdehyde and nitric oxide levels were determined. The rates of necrosis and apoptosis were evaluated by histopathological examination. RESULTS: The level of malondialdehyde was higher in the torsioned groups (Group 2, 3, 4, 5) than that in group 1 (p = 0.004). There was no statistically significant difference between the groups regarding the level of nitric oxide (p = 0.182). Apoptosis was higher in groups 2, 3 and 4 than in group 1; however, apoptosis was similar in group 1 and group 5 (p = 0.122). The level of necrosis in group 1 was similar to that in groups 4 and 5 (p = 0.194 and p = 0.847, respectively). CONCLUSION: We suggest that the administration of Rolipram can decrease the rate of necrosis and apoptosis in testicular ischaemia-reperfusion injury.

Should warm fresh whole blood be the first choice in acute massive hemorrhage in emergency conditions?

Early management of rapid massive hemorrhage requires early administration of blood products and rapid surgical control of bleeding. Professionals in peripheral hospitals with limited resources often work under conditions similar to those in the military. Described in the present report are 3 cases in which warm fresh whole blood (WFWB) was used in patients with massive bleeding who presented to a peripheral hospital that had no blood products suitable for emergency conditions. Described first is the case of a 16-year-old female patient who underwent emergency cesarean section. The patient had massive bleeding from the uterus due to atony. Her hemoglobin (Hb) dropped to 3.5 g/dL. Six units of WFWB were transfused during surgery. Hemodynamic parameters and complete blood count (CBC) stabilized. She was transferred from the intensive care unit (ICU) to obstetrics on day 2 and was discharged on day 7. Described second is the case of a 35-year-old female patient who also underwent emergency cesarean section, and for whom massive bleeding was due to uterine atony. Hb dropped to 2 g/dL and hematocrit (HCT) to 5.4%. Nine units of WFWB were transfused, after which hemodynamic and laboratory parameters stabilized. The patient was extubated the following day, transferred from the ICU to obstetrics on day 3, and was discharged on day 8. Described third is the case of a 36-year-old male patient with stab injuries and hemorrhagic shock who underwent emergency surgery. The patient had injuries to the right renal artery and kidney. Nine units of WFWB were transfused due to continued hemorrhage during surgery. Following surgical control of bleeding and transfusion, hemodynamic parameters improved. The patient was transferred from the ICU on day 5 and discharged on day 10. WFWB transfusion nearly disappeared from civilian medicine after blood was separated into components, and whole blood is not usually available at blood banks. In massive transfusions, WFWB effectively replaces red blood cells (RBCs), platelets, plasma volume, and coagulation factors, while preventing hypothermia and dilutional coagulopathy. Blood components go through biochemical, biomechanical, and immunological changes during long storage, the duration of which affects both transfusion efficacy and associated risks. In the future, with the use of fast donor tests, fast ABO compatibility tests, platelet-sparing leukocyte filters, and developments in pathogen-decreasing technology, fresh whole blood (FWB) may be the first choice for massive transfusion. Future studies will reveal new procedures.

Laparoscopic upper pole heminephrectomy in adults for treatment of duplex kidneys.

PURPOSE: To present our results of laparoscopic upper pole heminephrectomy in adult patients with duplex kidney. MATERIALS AND METHODS: A total of 10 patients with an age range of 27 to 54 years old underwent laparoscopic upper pole heminephrectomy for complete duplication of the renal collecting system. The key point of the technique included the placement of a catheter in the normal ureter at the beginning of the procedure. The patient was positioned in a 45-90 degrees lateral decubitus position and a 4-port transperitoneal or 3-port retroperitoneal technique was applied followed by the mobilization of the upper pole ureter away from the renal hilum. Afterwards, the vasculature supplying the upper pole was precisely identified and ligated. Followed by transection of the ureter and its transposition cephalad to the hilum, the upper pole moiety was fully transected using the harmonic scalpel. RESULTS: Eight patients were operated on using the transperitoneal approach and 2 using the retroperitoneal technique. One patient required preoperative percutaneous drainage due to pyonephrosis. The operation time ranged between 150 to 350 min with minimal blood loss (0-200 mL). Hemostasis was achieved with an Argon laser in one patient. The lower pole calyceal system was perforated in one patient and repaired intracorporally. No major intraoperative complications occurred. All of the patients except two had their drains removed in 72 h after the operation and were generally discharged on postoperative day 3. CONCLUSION: Laparoscopic upper pole heminephrectomy for an ectopic ureter is safe and reproducible and offers benefits of laparoscopic surgery even in patients with complicated urinary tract infection.

Microchimeric Cells, Sex Chromosome Aneuploidies and Cancer.

The phenomenon of feta-maternal microchimerisms inspires numerous questions. Many questions remain to be answered regarding this new avenue of genetics. The X and Y chromosomes have been associated with malignancy in different types of human tumors. We aimed to investigate the numerical aberrations of chromosomes X and Y in lung cancer (LC) and bladder cancer (BC) and review recent evidence for possible roles of microchimeric cells (McCs) in these cancers. We carried out cytogenetic analysis of the tumor and blood sampling in 52 cases of people with BC and LC, and also with 30 healthy people. A total of 48 (92.3 %) of the patients revealed sex chromosome aneuploidies (SCAs). A total SCAs was found in 9.8 % of 2282 cells that were analyzed as one or more cells in each case. The 68 and 95 SCAs were found in the 1952 (8.4 %) cells in peripheral blood, and 41 and 19 SCAs in the 330 (18.2 %) cells in the tumoral tissues respectively. There was a significant difference in the frequencies of SCAs between the patients and the control groups determined by the Fischer's Exact Test (p < 0.0001). The frequencies of SCAs were higher in the tumoral tissues than in the blood (p < 0.0001). There was a significant difference in the frequencies of SCAs between the tumor and blood tissues, and this was higher in the tumor tissue (p < 0.0001). In general, 78.9 % (41) of the 52 patients with LC and BC had X and Y chromosome monosomies. Largely a Y chromosome loss was present in 77.8 % of the men, and the 47, XXY karyotype was found in 33.3 % of them. The second most common SCA was monosomy X, and was found in 71.4 % of the women. McCs were observed in 26.9 % of the 52 patients, and the frequencies of McCs were higher in the blood than in the tissues (p < 0.0001). XY cells were identified in the lung and bladder tissues of the women who had been pregnant with boys, but not in those who had not. There was a significant difference in the frequencies of McCs between the LC and BC patients (p < 0.0005). We speculate that the microchimerism could have a general beneficial role in cancer, in which some sites may not be evident because of an allogeneic maternal immune reaction that hastens cancer development. A further understanding of McCs may help in anticipating its implications in cancer. Our results may suggest that SCAs may be contributing factors in the development of LC and BC, and aneuploidies of X and Y chromosomes play a role in the pathogenesis of cancers.

Genetic alterations of chromosomes, p53 and p16 genes in low- and high-grade bladder cancer.

A majority of patients with bladder cancer present with superficial disease and subsequently, some patients show progression to muscle invasive or metastatic disease. Bladder cancer has a complex genetic process and identification of the genetic alterations which occur during progression may lead to the understanding of the nature of the disease and provide the possibility of early treatment. The aim of the present study was to compare the structural and numerical chromosomal differences and changes in the p16 and p53 genes between low-grade (LG) and high-grade (HG) bladder cancer (BC) using cytogenetic and molecular cytogenetic methods. Between March 2009 and March 2010, cytogenetic analyses were carried out on tumor and blood samples in 34 patients with transitional cell type BC, and on blood samples of 34 healthy patients as a control group. Fluorescence in situ hybridization probes for the p16 and p53 genes were also used to screen the alterations in these genes in 32 patients with BC. The patients were divided into two groups (LG and HG) and the findings were compared. A total of 11 (32.3%) patients exhibited LGBC, 22 (64.7%) exhibited HGBC and one (3%) patient exhibited carcinoma in situ. There were no differences between the LGBC and HGBC groups according to the number of chromosomal aberrations (P=0.714); however, differences between alterations of the p16 and p53 genes were significant (P=0.002 and P=0.039). Almost all structural abnormalities were found to be located to the 1q21, 1q32, 3p21 and 5q31 regions in patients with HG tumors. In conclusion, the p16 and p53 genes were altered more prominently in patients with HG tumors compared with LG tumors. The structural abnormalities in the 1q21, 1q32, 3p21 and 5q31 regions were observed more frequently in patients with HG tumors. These regions may play significant roles in the progression of BC, but further studies are required to find candidate genes for a panel of BC.

Is urotherapy alone as effective as a combination of urotherapy and biofeedback in children with dysfunctional voiding?

ABSTRACT Objective: To compare standard urotherapy with a combination of urotherapy and biofeedback sessions and to determine the changes that these therapies promote in children with dysfunctional voiding. Patients and Methods: The data of 45 patients who participated in the study from January 2010 to March 2013 were evaluated. All patients underwent urinary system ultrasonography to determine post-void residual urine volumes and urinary system anomalies. All patients were diagnosed using uroflowmetry - electromyography (EMG). The flow pattern, maximum flow rate, and urethral sphincter activity were evaluated in all patients using uroflowmetry - EMG. Each patient underwent standard urotherapy, and the results were recorded. Subsequently, biofeedback sessions were added for all patients, and the changes in the results were recorded and statistically compared. Results: A total of forty - five patients were included, of which 34 were female and 11 were male and the average age of the patients was 8.4 ± 2.44 years (range: 5 - 15 years). After the standard urotherapy plus biofeedback sessions, the post-void residual urine volumes, incontinence rates and infection rates of patients were significantly lower than those with the standard urotherapy (p < 0.05). A statistically significant improvement in voiding symptoms was observed after the addition of biofeedback sessions to the standard urotherapy compared with the standard urotherapy alone (p < 0.05). Conclusions: Our study showed that a combination of urotherapy and biofeedback was more effective in decreasing urinary incontinence rates, infection rates and post - void residual urine volumes in children with dysfunctional voiding than standard urotherapy alone, and it also showed that this combination therapy corrected voiding patterns significantly and objectively.

Protective effects of phosphodiesterase-4-specific inhibitor rolipram on acute ischemia-reperfusion injury in rat kidney.

OBJECTIVE: To investigate the effect of Rolipram, a phosphodiesterase-4-inhibitor, on renal ischemia-reperfusion injury (IRI) in rats. METHODS: Thirty rats were divided into 5 different groups of 6 rats. Nothing was done to the control group. In the second group, the renal pedicle was clamped for 30 minutes. In the third group, 1 mg/kg of Rolipram was given by intraperitoneal injection 30 minutes before clamping. The fourth group received the same injection when the clamp was placed, as did the fifth group 30 minutes after the clamp was opened. Clamping time was set at 30 minutes. Twenty-four hours later, nephrectomy was performed in all the groups. Half of each kidney was examined histopathologically. Levels of biochemical agents, such as malondialdehyde, superoxide dismutase, and catalase, were measured in the other half. RESULTS: The malondialdehyde (MDA) levels significantly decreased and reached control levels in the group in which Rolipram was administered 30 minutes after reperfusion (P = .07). The catalase and superoxide dismutase activities obtained from renal homogentisates of the ischemia groups were evaluated; there were striking increases in tissue levels of these 2 enzymes in the groups in which Rolipram was administered during ischemia and 30 minutes after ischemia (P < .001). Histopathologically, there was no significant difference in inflammation between the Rolipram-administrated groups compared with group 1 (control) and group 2 (IRI). Tubular necrosis and apoptosis was significantly lower in group 5 than the other groups, except group 1 (P < .001). CONCLUSION: We suggest that in surgical procedures that can lead to renal IRI, the administration of Rolipram can decrease oxidative renal tissue damage and the severe deterioration of renal function.

Laparoscopic pyeloplasty in adults: stented versus stentless.

INTRODUCTION: In this study, we aimed to investigate the efficacy and feasibility of stentless laparoscopic pyeloplasty (LP), compared with the stented counterpart. MATERIALS AND METHODS: We compared the results of stented and stentless LP procedures performed at two centers. The indications included symptoms such as loin pain or urinary tract infection with documented obstruction on renal scintigraphy. Transperitoneal approach was standard for both techniques. The stented and stentless patient groups were compared with regard to surgical duration, length of hospital stay, postoperative symptomatology, complications, and radiologic and scintigraphic findings. RESULTS: Twenty-seven patients with stentless pyeloplasty with at least 6 months of follow-up were included in the study and compared with a matched group of 21 stented LP patients. All had Anderson-Hynes dismembered pyeloplasty. Mean operative time was 151.9 minutes and 144.6 minutes in the stented and stentless groups, respectively (p > 0.05). Mean drain removal time and hospital stay were 1.9 days (range: 1-9 days) and 3.4 days (range: 2-9 days) in the stented group, respectively, and 2 days (range: 1-10 days) and 3.1 days (range: 1-10 days) in the stentless group, respectively (p > 0.05). Renal scintigraphy studies improved in 14 patients in the stented group and in 22 patients in the stentless group during the 6-month follow-up. Symptoms completely resolved in 19 of the stented and in 24 of the stentless cases. CONCLUSION: Stentless LP is a feasible technique as its stented counterpart. Although it has a relatively high prolonged leakage risk, it could be performed without compromising the success rate by experienced surgeons.

MTHFR gene polymorphisms in bladder cancer in the Turkish population.

Bladder cancer is the 9th most common cancer and is responsible for malignancy related death all on the world. Folate and folate related enzyme polymorphisms related to the cancer risk. The methylene tethrahydrofolate reductase (MTHFR) enzyme is folate related and association of bladder cancer and MTHFR gene. Our purpose was to assess the prevalence of MTHFR gene 677 CT and 1298 AC polymorphisms and Bladder cancer in Turkey. We intended that bladder cancer patients and controls and we used the Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism (RFLP) methods. The MTHFR gene C677T and A1298C polymorphisms were associated with an increased risk of bladder cancer in our population (For the MTHFR gene C677T polymorphism and A1298C polymorphism; p=0.036<0.05; p=0.278>0.05 respectively). Consequently, the MTHFR gene C677T polymorphism augments the risk of bladder cancer in Turkey.

Pediatric transumbilical laparoendoscopic single-site nephroureterectomy: initial report.

OBJECTIVE: To present a case of laparoendoscopic single-site surgery (LESS) nephroureterectomy (NUx), a type of embroyonic natural orifice translumenal endoscopic surgery, which is one of the recent innovations in the era of laparoscopy, in a child. METHODS: A 10-year-old girl underwent left nephroureterectomy by LESS due to end-stage reflux nephropathy on December 25, 2008. The surgery is performed transperitoneally, through a 2-cm semicircular incision in the left inner curve of the umbilicus using three 5-mm trocars. NUx with LESS was performed duplicating standard laparoscopic steps with the help of flexible and straight laparoscopic instruments. RESULTS: Operation time was 140 minutes and the blood loss was minimal. There was no intraoperative or postoperative complication. The patient was discharged at the 24th postoperative hour. The postoperative cosmetic result was excellent as the incision scar was hidden inside the belly button. CONCLUSIONS: NUx with LESS is a feasible technique with the advantages of less pain, shortened convalescence, improved cosmesis, and absence of wound complications in children. However, clear indications of LESS in children remain to be clarified.
