Our experience of operated pediatric ureteropelvic junction obstruction patients.

AIMS: Ureteropelvic junction obstruction (UPJO) may originate from extrinsic or intrinsic causes in children. The aim of this study is to present preoperative and postoperative data of our patients operated for UPJO. METHODS: A total of 64 patients who underwent open pyeloplasty were investigated retrospectively. They were evaluated in terms of demographically, clinics, hydronephrosis, differential renal functions (DRFs), half-time tracer clearance (½TC), and histopathologic results. Patients' numerical results were stated as mean ± standard deviation (SD). RESULTS: Male gender was more prevalent (n = 47, 73.4%) and mean age at surgery was 46.87 months. UPJO was located at the left side in 56.3% (n = 36), and at the right side in 39.1% (n = 25) of patients. It was bilateral in 4.7% (n = 3). Hydronephrosis was found antenatally in 68.8% (n = 44) of patients. The mean preoperative DRF was 49.7% (21-78%) and mean postoperative DRF was 49.2% (20-56%). Mean renal scintigraphic t1/2 was >20 min for all patients. The mean AP diameter was 21.58 mm (10-62 mm). Muscular hypertrophy was the most common pathological finding, mean length of excised segment was 10.26 mm (3-40 mm). Crossing vessel (CV) was detected in 17.18% (n = 11). The CV was statistically associated with increased age of operation, left side, and female gender. Statistically significant hydronephrosis was found in non-CV patients. Re-operation was required in seven patients (7.8%). CONCLUSIONS: Intrinsic pathologies are more seen in the etiology of UPJO patients with antenatal diagnosis and this group needs operation at an earlier age. However, CV is found more commonly in patients who are diagnosed and operated at older ages.

Efficiency of radiation-free retrograde intrarenal surgery (RIRS) in children and evaluation of factors affecting surgical success. / Eficiencia de la cirugía intrarenal retrograda sin radiación en niños y evaluación de los factores que afectan el éxito quirúrgico.

OBJECTIVE: To investigate the factors affecting surgical success rates and duration of operation in retrograde intrarenal surgery (RIRS) without fluoroscopy in children. The aim of the study was to demonstrate the efficacy of RIRS without fluoroscopy on the treatment of renal stones in children. MATERIALS AND METHODS: All RIRS procedures were performed on pediatric patients at our clinic from August 2013 to January 2017. We studied 52 pediatric patients who had one stone in one kidney and under went one session. We mapped the kidney collecting system anatomically, and stone localization was defined according to this mapping. Size and localization of the stone, placement of preoperative J stent, use of ureteral access sheath (UAS), and surgical success rates were recorded. The effects of these factors on surgical success rates and the duration of the operations were analyzed. RESULTS: Each patient underwent RIRS once. Of these 52 pediatric patients, 23 (44%) were between 0-5 years of age children (Group 1), 13 (25%) were between 6-11 years of age children (Group 2), and 16 (31%) were between 11-17 years of age children (Group 3). The surgical success rates for each group were 65%, 77%, and 81%, respectively (73% overall). The surgical success rates were found to be affected only by stone size (p<0.01). The durations of the operations were found to be affected by stone size, stone localization, passive dilatation of ureter, and the application of an UAS (p<0.05). CONCLUSION: RIRS is a safe and effective method for the treatment of intrarenal stones in pediatric patients. High success rates can be achieved using kidney mapping without the use of fluoroscopy.

OBJETIVO: Investigar los factores que afectan el éxito quirúrgico y la duración de la cirugía retrógrada intrarenal sin fluoroscopia en niños. El objetivo de este estudio fue demostrar la eficacia de la cirugía retrógrada intrarenal sin fluorosocopia en el tratamiento de litiasis en niños. MÉTODOS: Todos los procedimientos de cirugía retrógrada intrarenal fueron realizados en pacientes pediátricos en nuestra clínica entre agosto 2013 y enero 2017. Estudiamos 52 casos pediátricos con 1 litiasis en 1 riñón y recibieron una sesión. Marcamos el sistema colector renal y la litiasis se definió según ese marcaje. El tamaño y la localización de la piedra, colocación preoperatoria del doble J, la vaina de acceso y la tasa de éxito quirúrgico fueron reportadas. Los efectos de estos factores en el éxito quirúrgico y la duración de las cirugías fueron analizados. RESULTADOS: Cada paciente recibió cirugía retrógrada una vez. De éstos 52 pacientes pediátricos, 23 (44%) tenían entre 0 y 5 años (grupo 1), 12 (25%) entre 6 y 11 años (grupo 2), 16 (31%) entre11 y 17 años (Grupo 3). El éxito quirúrgico en cada grupo fue de 65%, 77% y 81% respectivamente (73% en general). El éxito quirúrgico se vió afectado sólo por el tamaño de la litiasis (p<0,01). La duración de las cirugías se vió afectada por el tamaño de la litiasis, localización de la litiasis, dilatación pasiva del uréter, y uso de la vaina de acceso (p<0,05).CONCLUSIÓN: La cirugía intrarenal retrógrada es segura y efectiva en el tratamiento de litiasis intrarenales en el paciente pediátrico. Altas tasas de éxito se consiguen con el mapeo renal sin fluoroscopia.

Modified Makuuchi incision in the surgical treatment of renal tumors: Initial results.

OBJECTIVE: To evaluate the modified Makuuchi incision in the surgical treatment of renal tumors. MATERIAL AND METHODS: A total of 29 patients with renal tumors were operated using the modified Makuuchi incision. Patients' age ranged from 48 to 72 years. Twenty-three patients were male, and 6 patients were female. Renal tumors affected the right side in 22 patients and the left side in 7 patients. Twenty-six patients underwent radical nephrectomy, while 3 patients underwent partial nephrectomy. RESULTS: A perfect exposure was achieved with this incision in the surgical field. No serious complications such as bleeding or other organ injuries happened during the surgery. Blood transfusion during surgery was unnecessary. Additional use of analgesics due to wound pain during the postoperative period was not required. Incision-related complications, such as wound infection and wound dehiscence, did not occur in the early postoperative period. Patients had no complaints about the cosmetic appearance of their abdomen due to the incision. Incisional hernia was not observed in patients. CONCLUSION: This type of incision provided a perfect exposure of the field in the surgical treatment of renal tumors.

The efficacy of Tadalafil 5mg in the treatment of lower urinary tract symptoms in patients where alpha blocker treatments have failed in terms of lower urinary tract symptoms. / Eficacia de Tadalafilo 5 mg en el tratamiento de los síntomas del tracto urinario inferior en pacientes tras fallo de los alfabloqueantes.

OBJECTIVES: To investigate the efficacy of tadalafil 5mg in patients with lower urinary tract symptoms who failed alpha blocker treatment. PATIENTS AND METHODS: Twenty-three patients were included. Patient consent was obtained after explaining the efficacy of tadalafil 5mg in lower urinary tract symptoms. Before initiating tadalafil 5mg treatment, prostate cancer and urinary tract infection in the patients were eliminated. IPSS, IIEF-5 and Qmax values were assessed before and one month after tadalafil 5mg treatment. Difference between two assessments was evaluated by the Wilcoxon method. RESULTS: After 1 month of Tadalafil 5mg treatment, IPSS decreased and IIEF-5 and Qmax increased. The difference between two assessments were statistically significant. CONCLUSION: Tadalafil 5mg once daily in the treatment of BPH/LUTS is found to be successful in patients who failed previous alpha blocker treatment.

OBJETIVOS: Investigar la eficacia de tadalafilo 5 mg en pacientes con síntomas del tracto urinario inferior (STUI) tras fallo de los alfabloqueantes. PACIENTES Y MÉTODOS: Treinta y tres pacientes fueron incluidos. Se obtuvo consentimiento informado en todos los casos tras explicarles la eficacia del tadalafilo 5 mg en el tratamiento de los STUI. Antes de iniciar el tratamiento se descartaron cáncer de próstata e infección urinaria. Se evaluaron los valores de los cuestionarios IPSS, IIEF-5 y el Q max antes del tratamiento y al mes del tratamiento. Las diferencias entre los grupos se evaluaron utilizando el método de Wilcoxon.    RESULTADOS: Después de un mes con tadalafilo 5 mg, el IPSS disminuyó, y el IIEF-5 y el Q max aumentaron. Las diferencias fueron estadísticamente significativas. CONCLUSIONES: Se ha visto que el tadalafilo 5 mg una vez al día es eficaz en el tratamiento de los STUI/HBP en pacientes con fallo previo del tratamiento con alfabloqueantes.

Exenatide reduces oxidative stress and cell death in testis in iron overload rat model.

Glucagon-like peptide-1 (GLP-1) has been demonstrated to affect the oxidative stress status in several in vitro, in vivo and clinical studies. The aim of the present study was to evaluate the effect of a GLP-1 analogue, exenatide, on oxidative stress parameters and apoptotic markers in testicular cells in an iron overload rat model. To obtain this model, the animals were randomly divided into three groups (n=6/group). Rats in the control group received intraperitoneal injections of saline. Intraperitoneal iron dextran (60 mg/kg/day) was given to Group FE for 5 days a week for 4 weeks. The third group (Group Fe +E) was given subcutaneous injections of 10 µg/kg exenatide in two divided doses for 4 weeks in addition to iron dextran. Testes of all rats were immediately removed for immunohistochemical staining and to measure the malondialdehyde level and superoxide dismutase enzyme activity. A significant reduction was observed in caspase-8 and -3 enzyme staining in testicular stromal and endothelial cells in exenatide injected iron overloaded rats when compared with controls. Oxidative stress markers malondialdehyde levels and superoxide dismutase enzyme activities were also significantly lower in exenatide-injected rats when compared with controls. These findings indicate that exenatide may be protective against the harmful effects of iron accumulation in testis. Further studies are required to evaluate how exenatide reduces oxidative stress and cell death in iron overloaded testis tissue.

Prognostic role of preoperative albumin to globulin ratio in predicting survival of clear cell renal cell carcinoma.

PURPOSE: To investigate the prognostic role of preoperative albumin/globulin ratio (AGR) in predicting disease-free survival (DFS) and overall survival (OS) in localized and locally advanced clear cell renal cell carcinoma (RCC) patients. PATIENTS AND METHODS: 162 patients who met the criteria specified were included in the study. The DFS and OS ratios were determined using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were performed to determine the prognostic factors affecting DFS and OS. RESULTS: Median follow-up period was 27.5 (6-89) months. There was a statistically significant relationship between low AGR and high pathological tumor (pT) stage, presence of collecting system invasion, presence of tumor necrosis, and a high platelet count (p = 0.012, p = 0.01, p = 0.001, and p = 0.004, respectively). According to the Kaplan-Meier survival analysis, both OS and DFS were found to be significantly lower in the low AGR group (p = 0.006 and p = 0.012). In the multivariate Cox regression analysis, collecting system invasion and tumor necrosis were found to be independent prognostic factors in predicting OS and pT stage was found to be an independent prognostic factor in predicting DFS (HR: 4.08, p = 0.043; HR: 8.64, p = 0.003 and HR: 7.78, p = 0.041, respectively). CONCLUSION: In our study, low AGR was found to be associated with increased mortality and disease recurrence in localized and locally advanced RCC.

Retrograde intrarenal surgery by flexible ureteroscope in patients with spinal deformities.

OBJECTIVE: To present our experience with retrograde intrarenal surgery (RIRS) for managing renal stones in patients with spinal deformities. DESIGN: We retrospectively reviewed the records of patients. METHODS: We retrospectively reviewed the records of seven patients with congenital scoliosis (n = 5), spina bifida (n = 2) who had undergone RIRS for renal stones. Stone-free status was determined by CT 30 days after the procedure and was defined as the absence of stones in the kidney or residual fragments ≤1 mm. RESULTS: Mean patient age was 27 years (18-45 years), and mean stone size was 176 mm (143-340 mm). The average operative time was 38 minutes (25-53 minutes), and postoperative hospital stay was 1 day (1-2 days). A stone-free status was obtained in six (85.7 %) patients, and one patient was considered to have treatment failure. This patient was managed by a repeat RIRS. A Double-J stent was placed at the end of the procedure in all (100 %) patients. No severe complications, either from anesthesia or the surgical procedure, were observed, and no blood transfusion was reported. CONCLUSIONS: The good clearance rate with a low incidence of complications shown by the present study has demonstrated that RIRS is a safe and effective procedure for renal stones in patients with spinal deformities.

Seperation of dorsal vein complex from the urethra by blunt finger dissection during radical retropubic prostatectomy.

We present our initial experience on the isolation of dorsal vein complex by blunt finger dissection in 26 patients with localised prostate cancer who underwent open retropubic radical prostatectomy. Loss of blood was between 300 and 500 mL (mean 350 mL). Two of 26 patients (7.6%) required blood transfusion. There was no positive surgical margin at prostatic apex in the patients. Twenty four of our patients (92.4%) were continent on the 3(rd) month. Control of dorsal vein complex is very important to decrease blood loss and to improve intraoperative exposure of retropubic area in order to get negative margin of prostatic apex and to provide the urethra long enough for a nice urethrovesical anastomosis. According to our initial experience, this technique seems to provide these aims.

Comparative analysis of pedicular vascular control techniques during laparoscopic nephrectomy: en bloc stapling or separate ligation?

OBJECTIVE: To compare the safety and efficacy of en bloc stapling and separate ligation techniques for renal vascular control during laparoscopic nephrectomy. PATIENTS AND METHODS: Clinical data were collected from 60 patients who underwent laparoscopic nephrectomies using en bloc stapling (n = 27, group 1) or the separate ligation method (n = 33, group 2). Comparative analysis was carried out between the two groups, examining operative times, blood loss, intra- and postoperative complications and hospital stay. RESULTS: Compared with the separate ligation method, the en bloc hilar control technique was associated with a shorter total operating time (98 vs. 121 min, p = 0.029). However, both groups were similar in terms of estimated blood loss, hemoglobin drop, changes in creatinine level and postoperative hospital stay. The total complication rates in group 1 and 2 were 3.7 and 15.1%, respectively, with a statistically significant difference. There were no complications related to the use of the endo-GIA stapler and no patients required conversion to open surgery in group 1. In group 2, 2 patients required conversion to open surgery, including 1 due to renal vein bleeding secondary to inaccurate vascular control and the other due to bleeding from the vena cava during dissection. In addition, 1 patient had a superficial bowel injury that was repaired laparoscopically and another had a superficial liver tear that was managed without conversion or transfusion. CONCLUSION: En bloc ligation of the renal hilum is an easy and reliable technique that allows safe and fast control of the renal pedicle.

Direct upper kidney pole access and early ligation of renal pedicle significantly facilitates transperitoneal laparoscopic nephrectomy procedures: Tunc technique.

We modified our technique in transperitoneal laparoscopic nephrectomies and compared its results with the classical technique. Classical technique was performed in 85 cases (group 1). Modified technique (n=98) included direct kidney upper pole access and early ligation of renal pedicle (group 2). No significant differences were detected regarding mean patient age, intraoperative blood loss, and duration of hospital stay between the 2 groups (P>0.05). Mean operation time was 64.9 ± 19.3 and 28.2 ± 7.7 minutes, respectively in groups 1 and 2 (P=0.001). Mean operation time including right nephrectomies was 68.7 ± 23.4 and 24.2 ± 6.3 minutes, respectively in groups 1 and 2 (P=0.001). Mean operation time including left nephrectomies was 63.8 ± 17.1 and 33.6 ± 5.1 minutes, respectively in groups 1 and 2 (P=0.001). Similarly, mean operation time was significantly shorter in group 2 when analysis was performed among right and left radical and simple nephrectomies between the 2 groups (P=0.001). Direct upper kidney pole access and early ligation of renal pedicle seems to be significantly facilitating transperitoneal laparoscopic nephrectomy procedures.

Treatment outcomes of semirigid ureterorenoscopy and intracorporeal lithotripsy in pregnant women with obstructive ureteral calculi.

The purpose of the study is to evaluate the outcomes of semirigid ureterorenoscopy and intracorporeal lithotripsy as a definitive treatment in pregnant women with obstructive ureteral calculi. A retrospective analysis was performed of 16 pregnant patients referred to gynecology department with ureteral obstruction from 2007 to 2009. The mean age was 25 years, and mean gestation period was 30 weeks. Of the 16 patients; 50% had fever, 100% flank pain, 56% dysuria, 25% gross hematuria, 50% positive urine culture, and 75% pyuria and microscopic hematuria. Abdominal ultrasonography was the principle diagnostic test used. The mean stone size was 9.45 mm. Eleven of the 16 patients, 54% had stones located in the distal ureter and 46% proximal ureter. The stones were fragmented using a swiss pneumatic lithoclast through 9.5 F semirigid ureteroscope by 0.035 mm safety guidewire with the patient under general anesthesia. Eleven patients had obstruction due to the ureteral calculi. Eight of 11 patients had complete fragmentation of the calculi by ureteroscopy as a primary treatment. Push-back was performed in the other three patients. By applying Dj catheter, and performing eswl after giving birth, the patient became stone-free. Dj catheter was applied peroperative to all 16 patients. No complications were recorded, and all patients completed the full term of pregnancy. The results of our study have shown that semirigid ureteroscopy to diagnose ureteral calculi and treat them with intracorporeal pneumatic lithotripsy and ureteral stent insertion, as indicated, is the most efficient and definitive treatment modality in pregnant women.

The impact of transrectal prostate needle biopsy on sexuality in men and their female partners.

OBJECTIVES: To evaluate sexuality in men who have undergone transrectal prostate needle biopsy (TPNB) and their female partners. METHODS: Ninety-seven men underwent TPNB because of high prostate-specific antigen level (>or=2.5 ng/mL) and/or abnormal digital rectal examination findings and their female partners were included in this study. Men were evaluated for erectile function before biopsy, and the first and sixth months after the biopsy with the 5-item version of the International Index of Erectile Function (IIEF-5). Female partners completed the Female Sexual Function Index (FSFI) in the same periods together with the men. We assessed IIEF-5 and FSFI score alterations after the biopsies. RESULTS: The mean ages of men and their partners were 61.2 (40 to 81) years and 56.8 (34 to 70) years, respectively. The mean IIEF-5 scores were 19.1 +/- 5.8, 17.1 +/- 5.9, and 16.8 +/- 7.5 before the biopsy, and 1 and 6 months after the biopsy, respectively. We found significant differences among prebiopsy IIEF-5 scores and postbiopsy first- and sixth-month IIEF-5 scores (P <0.001). On the contrary, there was no significant difference between the postbiopsy first- and sixth-month IIEF-5 scores (P = 0.335). In the female partners, the mean prebiopsy, postbiopsy first- and sixth-month total FSFI scores were 18.0 +/- 6.8, 16.2 +/- 6.8, and 16.0 +/- 8.4, respectively (P <0.001). In first- and sixth-month postbiopsies, all FSFI subscores were significantly lower than the prebiopsy subscores. CONCLUSIONS: TPNB seems to have negative impact on erectile function. Male sexual dysfunction after TPNB also has a negative effect on female sexual function. We believe that couples should be informed about the risk of erectile dysfuncton before TPNB.

The association of 5alpha-reductase II (SRD5A2) and 17 hydroxylase (CYP17) gene polymorphisms with prostate cancer patients in the Turkish population.

To date, research has led to the invention of multiple genes and their single nucleotide polymorphisms (SNPs) and environmental factors that influence the prostate cancer (PCa) pathogenesis. Therefore, the genes involved in these pathways are candidates for PCa predisposition. It is thought that polymorphisms of 5alpha-reductase II (SRD5A2) and 17 hydroxylase (CYP17) genes are likely to increase susceptibility. The aim of this study was to investigate the risk association of SRD5A2 and CYP17 gene polymorphisms in the development and progression of PCa in the Turkish population. In this study, 100 PCa patients and 105 healthy controls were studied. SRD5A2 and CYP17 gene polymorphisms were determined by real-time PCR and polymerase chain reaction-restriction length polymorphisms (PCR-RFLP) techniques. First, the AT and TT genotypes of SRD5A2 gene at codon 49 were not observed. Second, there was no significant association between the polymorphisms at codon 89 and the risk of PCa. Third, in the CYP17 gene, the A1A1 genotype is more common (46%) in cases than controls (32.4%). The odds ratios (ORs) of the A1A1 genotype was found at 1.69 (95% confidence interval [CI], 0.77-3.74) compare with the A2A2 genotype. Genotyping results of the SRD5A2 and CYP17 genes were also analyzed in relation to prostate-specific antigen (PSA) levels, Gleason score (GS), and tumor stage, but no statistically significant difference was observed (P > 0.05). Finally, we conclude that there was no evidence of an association between CYP17 (P = 0.134) and SRD5A2 (P = 0.784) polymorphism and PCa risk in the Turkish population.

Preputial bacterial colonisation in preschool and primary school children.

OBJECTIVES: Preputial bacterial colonisation was investigated in preschool and primary school children with and without phimosis before the circumcision procedure. METHOD: The study group consisted of 32 boys admitted to our clinic consecutively between June 2003 and September 2003 for circumcision. The indication for surgery was religious belief in all patients. Immediately before the procedure, a swab was swept circumferentially once around the surface of the glans starting just proximal to the urethral meatus. In case of phimosis the same procedure was performed after complete retraction of the foreskin avoiding external contamination. The cultures were repeated in all patients after cleansing the glans and nearby preputium with polyvidon-iodine solution. RESULTS: The mean age of the patients' was 6 (4-12) years. All 5 (100%) patients with phimosis had clinically significant (> or =100,000 cfu/ml) uropathogenic bacterial colonisation. In 27 (84.3%) patients without phimosis culture reports revealed the absence of growth in 8 (29.6%) patients while 3 (11.1%) had Diphteroids and 1 (3.7%) had alpha-haemolytic Streptococci isolated from their preputial swabs which were accepted as harmless skin commensals. The rest of the boys (55.5%) had uropathogenic species in their preputium and all except 2 (7.4%) cases had counts exceeding 100,000 cfu/ml. The overall rates for individual species including any count were found as E. coli 3.1%, Klebsiella 18.8%, coagulase-negative Staphylococci12.5% and Enterococcus 43.8%. Cleansing of perimeatal and periurethral region with 10% polyvidon-iodine solution markedly decreased the bacterial count in 80% of the patients with phimosis. Including eight patients with no growth before cleansing 88.9% of the patients in the non-phimosis group were free of preputial bacteria after cleansing with iodine solution. CONCLUSION: Significant preputial colonisation with uropathogens might still be present in preschool and primary school children.

Renal brucelloma: a rare infection of the kidney.

We report a case of renal abscess caused by brucellosis (renal brucelloma) which was treated by surgery. Renal parenchymal involvement of systemic brucellosis is a very rare condition and relapses after medical treatment, such as solid organ abscess including kidney, should be especially considered. In chronic cases, laboratory findings including polymerase chain-reaction examination is needed for definitive diagnosis.
