RESUMO

INTRODUCTION: Increased depression and anxiety incidence in infertile individuals treated with assisted reproductive techniques have been shown in studies. Postoperative pain perception after testicular sperm extraction (TESE) is thought to be related to preoperative anxiety in non-obstructive azoospermia (NOA). MATERIALS AND METHODS: Twenty patients with Klinefelter syndrome (KS) and twenty male patients with normal karyotype NOA planned for TESE under local anaesthesia due to azoospermia were included in the study. Spielberger State-Trait Anxiety Inventory (STAI-T and STAI-S) inventory was given to all patients 1 h before surgery. Postoperative pain evaluation was performed at 0, 30, 60 and 120 min with visual analogue scale (VAS). STAI-T inventory was given to the patients again 2 h after the procedure. RESULTS: Preoperative STAI-S and STAI-T scores and postoperative STAI-T scores of patients in the KS group were higher than those in the NOA group, and there was a significant difference in the statistical analysis between the two groups (p < 0.001). In the postoperative VAS scores, there was no statistical difference at the 0 and 120th min (p = 0.56 and p = 0.87, respectively); at the 30, 60 and 90th min there was a statistically significant difference between the two groups, especially in patients in the KS group (p < 0.05, p < 0.05, p < 0.01, respectively). CONCLUSION: The contribution of anxiety to pain perception should be kept in mind in azoospermic male patients before TESE, and additional measures should be taken considering that this may be experienced at a higher level in KS patients.

RESUMO

INTRODUCTION: The 46,XX male syndrome is a rare disorder of sex development and has two different forms, depending on the sex-determining region's presence on the Y chromosome (SRY) gene. The SRY positive 46,XX males are usually diagnosed during infertility workup. We evaluated the erectile function of 46,XX SRY positive males and compared it with healthy males. MATERIAL AND METHODS: Ten patients with azoospermia and 46,XX SRY positive disorder who referred to a urology clinic with infertility were analyzed retrospectively. Controls were chosen from healthy males at similar ages. The physical examination was performed, and serum hormones were obtained at admission. The clinical assessment of erectile dysfunction was evaluated by the International Index of Erectile Function (IIEF) questionnaire. RESULTS: There was no statistically significant difference between the two groups in terms of age, serum prolactin, luteinizing hormone (LH) levels and IIEF scores (P >0.05). In 46,XX males, serum follicle-stimulating hormone (FSH) levels were significantly higher, and total testosterone levels and testicular volumes were found to be significantly lower when compared to controls (p <0.001, p <0.05, p <0.01, respectively). CONCLUSIONS: This study indicates that these males' erectile function is similar to those of 46,XY males.

RESUMO

If spermatozoa cannot be found after testiculer sperm extraction (TESE) in patients followed up due to nonobstructive azospermia (NOA) and the patients do not want donor spermatozoa, performance of round spermatid injection (ROSI) with the current technology seems to be the last resort. This retrospective study was conducted to evaluate the effect of testicular morphology on the development of embryos to the blastocyst stage obtained from ROSI. Between September 2019 and March 2020, after TESE and biopsy 29 patients who had only spermatid were taken to study. Tubular appearance, basal membrane appearance, Johnson score, peritubular fibrosis, interstitial fibrosis, and Leydig cell proliferation were pathologically examined. Following egg collection, ROSI was applied to the oocytes using the piezoelectric method. The embryos were monitored until the blastocyst stage. The mean age of the 29 patients was 36.3±5.01 years. Also, 7 patients had not previously undergone TESE, 20 had previously undergone once, and 2 had previously undergone twice. It was observed that having a history of TESE and a high Johnson score increased the likelihood of the embryo remaining in the blastocyst stage (P=0.021 and 0.014, respectively). However, other parameters do not affect the likelihood of blastocyst formation (P>0.05). Low TESE history and high Johnson score were associated with embryo development to the blastocyst stage. If spermatozoa are not found in patients with nonobstructive azoospermia, ROSI performed during initial TESE increases the likelihood of blastocyst formation.

RESUMO

PURPOSE: To evaluate the effect of a new mesenchymal stem cell type derived from the neonatal bladder (nMSC-B) on diabetic bladder dysfunction (DBD). MATERIALS AND METHODS: nMSC-B were harvested from neonatal male Sprague-Dawley rat's bladder and expanded in culture. nMSC-B were transferred to Type-1 diabetic rats which were induced by a single dose 45 mg/kg Streptozocin (STZ). Stem cells were transferred via intraperitoneally (IP) (DM-IP group, n:6) and by direct injection to the detrusor (DM-D group, n:6) at 12th week following diabetes and compared with Phosphate Buffered Saline (PBS) injected diabetic rats (DM-PBS group, n:6) and age-matched PBS injected non-diabetic normal rats (NR-PBS group, n:6). All rats were evaluated histopathologically and functionally four weeks after the stem cell treatment. RESULTS: nMSC-B showed improvement in both voiding function and bladder structure. The maximum voiding pressure (MVP) values in the DM-PBS group were lower compare to DM-IP, DM-D and NR-PBS groups (13.27 ± 0.78 vs 16.27 ± 0.61, 28.59 ± 2.09, 21.54 ± 1.00, respectively, P < .001). There was a significant improvement for MVP values in stem cell-treated groups. Immunohistochemical examination revealed decreased bladder smooth muscle (SM), increased fibrosis and desquamation in urothelia in diabetic groups compared to normal group(P < .001). We detected recovery in the stem cell groups. This recovery was more evident in DM-D group.  No statistical difference was observed in SM and fibrosis between DM-D and NR-PBS groups (P = .9). CONCLUSION: It was shown that nMSCBs provided amelioration of DBD. We think that nMSC-B constitutes an effective treatment method in DBD.

RESUMO

PURPOSE: The mean platelet volume (MPV) has important role in the pathophysiology of vascular diseases as a marker of the platelet activity. To investigate the association between mean platelet volume and erectile dysfunction (ED) and to search whether this marker can be used for diagnosis of ED. MATERIALS AND METHODS: Of the 312 patients with ED of various degrees, 122 patients without ED (IIEF-5>21) were included in this prospective study. Severity of ED was determined according to IIEF-5 questionnaire. MPV, fasting serum glucose, cholesterol, low density lipoprotein (LDL) and serum testosterone levels are also recorded. The mean platelet volume was calculated by the Coulter counter technique and sexual function was determined by International Index of Erectile Function erectile function domain (IIEF-5). RESULTS: The mean age of patients was 58.4 years. The mean MPV value of patients with ED was significantly higher compared to the non-ED patients (8.91 vs. 8.22, p = 0.0001). The severity of ED was shown to have a positive strong correlation with MPV values (r=0.719, p = 0.001). Mean serum triglyceride, glucose, total cholesterol and LDL cholesterol levels were noted higher in patients with ED. MPV values were found to be significantly higher in patients with ED. CONCLUSION: MPV level shows significant correlation with severity of ED. This cheap laboratory test can have potential to be a marker of ED. Further prospective larger studies with vascular wall thickness measurements should be conducted


OBJETIVO: El volumen plaquetario medio (VPM) desempeña un papel importante en la fisiopatología de las enfermedades vasculares como marcador de la actividad plaquetaria. El objetivo fue investigar la asociación entre el VPM y la disfunción eréctil (DE), y averiguar si este marcador puede utilizarse para el diagnóstico de la DE. MATERIALES Y MÉTODOS: De los 312 pacientes con disfunción eréctil de diversos grados, 122 pacientes sin disfunción eréctil (Índice Internacional de la Función Eréctil [IIEF-5]>21) se incluyeron en este estudio prospectivo. La gravedad de la DE se determinó según el cuestionario IIEF-5. También se analizaron el VPM, la glucosa sérica, el colesterol, la lipoproteína de baja densidad (LDL) y los niveles séricos de testosterona. El volumen plaquetario medio se calculó mediante la técnica de contador Coulter y la función sexual se estableció mediante el dominio de la función eréctil del IIEF-5. RESULTADOS: La media de edad de los pacientes fue de 58,4 años. El valor medio del VPM de los pacientes con DE fue considerablemente mayor en comparación con los pacientes sin DE (8,91 frente a 8,22; p = 0,0001). La gravedad de la DE mostró una fuerte correlación positiva con los valores de VPM (r=0,719; p = 0,001). Los niveles séricos de triglicéridos, glucosa, colesterol total y colesterol-LDL fueron más altos en pacientes con DE. Los valores del VPM se encontraron considerablemente mayores en pacientes con DE. CONCLUSIÓN: El nivel del VPM muestra una correlación importante con la gravedad de la DE. Esta prueba de laboratorio barata puede tener el potencial de ser un marcador de DE. Se deben realizar más estudios prospectivos más grandes con mediciones del espesor de la pared vascular

RESUMO

OBJECTIVE: This study was designed to evaluate the prevalence of Human Papilloma Virus (HPV) in semen and document the cycle outcomes in couples with previous intra-cytoplasmic sperm injection (ICSI) failures. MATERIAL AND METHODS: One hundred and seventeen couples with at least two ICSI attempts were included in the study. HPV infection in semen and DNA fragmentation in samples were analyzed by commercially available kits. The percentage of spermatozoa with fragmented DNA (DNA fragmentation index: DFI) was determined during fluorescence microscopic examination as previously described. The cycle outcomes of couples with or without HPV infected male partners were recorded. RESULTS: According to our results, the prevalence of HPV was 7.7% in asymptomatic males with at least two previous ICSI failures. The increased DFI (>30%) was observed in 82.9% of the cases. In HPV-positive cases significantly lower number of good quality embryos were obtained. The implantation and pregnancy rates were similar in infected and non-infected males (p>0.05). The early miscarriage rate was slightly higher in HPV- positive group (33% vs. 10%, p>0.05). CONCLUSION: In cases with previous ICSI failures, the prevalence of HPV infection in semen is not higher than previously reported infertile populations. The reproductive outcome might be impaired in HPV-positive semen due to lower number of good quality embryos, which needs to be clarified by further large population-based studies.

RESUMO

PURPOSE: In the treatment of interstitial cystitis, intravesical hyaluronic acid application may be suggested as a treatment option. In this randomized prospective study, the authors aimed to identify whether instilling the hyaluronic acid with electromotive drug administration (EMDA) would increase the tissue uptake and improve the efficacy. MATERIALS AND METHODS: The data of 31 patients who had been diagnosed with bladder pain syndrome/interstitial cystitis (BPS/IC) between 2004 and 2005 were examined. The patients were randomized to two groups: patients in group A received hyaluronic acid directly with a catheter and patients in group B received hyaluronic acid with EMDA. The patients were followed for 24 months and the two groups were compared at certain time intervals. The primary end points of the study were visual analogue scale (VAS) score, global response assessment, and micturition frequency in 24 hours. RESULTS: There were 6 males and 25 females. The two groups were similar in baseline parameters. The decrease in VAS score and the micturition frequency in 24 hours were significantly lower with EMDA at months 6 and 12. The difference between the two groups was not significant at months 1 and 24. Also, treatment with EMDA, positive KCl test, and pretreatment voiding frequency >17 were associated with higher response rates. CONCLUSIONS: Hyaluronic acid installation is an effective glycosaminoglycan substitution therapy in patients with BPS/IC. Instillation of hyaluronic acid via EMDA can improve the efficacy of the treatment; however, lack of long-term efficacy is the major problem with this glycosaminoglycan substitution therapy.

RESUMO

OBJECTIVE: To investigate the roles of bladder wall thickness (BWT) measurement and full/empty (F/E) BWT measurement ratio in the diagnosis of dysfunctional voiding in pediatric population. METHODS: Totally, 324 patients were involved in this prospective study, and group 1 consisted of healthy children (n=198), and group 2 consisted of patients with dysfunctional voiding (n=126). BWT measurements were done at the anterior, posterior, and lateral walls, and F/E BWT ratios were calculated. Two groups were compared for BWT measurement, and receiver operating characteristic analysis was performed to find out a cutoff value for BWT and F/E BWT ratios. RESULTS: Mean age of group 1 was 6.4 years and that of group 2 was 6.5 years. BWT measurements were higher in the empty state compared with full state and in boys compared with girls. However, BWT ratios did not show significant difference between male and female patients. F/E BWT ratios were found to be higher in group 2 compared with group 1 (P=.02). In receiver operating characteristic analysis, a cutoff value of 0.324 (sensitivity 66.67% and specificity 79.80%) and 0.295 (sensitivity 83.33% and specificity 64.14%) was found for anterior and posterior F/E BWT rates, respectively. CONCLUSION: Ultrasonographic measurement of BWT and calculation of F/E BWT ratio may serve as a noninvasive tool for evaluating lower urinary tract symptoms in children. Further studies including larger number of patients would be of great interest.

RESUMO

PURPOSE: To evaluate the postoperative analgesic efficacy of penile block, caudal block and intravenous paracetamol administration following circumcision. MATERIALS AND METHODS: In this prospective randomized study a total of 159 patients underwent circumcision under general anesthesia at urology clinic of Ufuk University Faculty of Medicine and Sorgun State Hospital between May 2012 and September 2012. The patients were randomized to three groups to receive penile block (Group 1), caudal block (Group 2) and intravenous paracetamol administration (group 3). Pain measurement of the patients was done via CHEOPS scoring system at 30,60,120 and 180 minutes postoperatively and compared. Statistical tests were performed with a conventional statistics program and statistical significance was set at a p value of < 0.05. RESULTS: The mean age of the patients was 5.7 years. Patients in group 1 had significantly lower pain score at 30 minutes compared to other two groups. At 60 minutes groups 1 and 2 had significantly lower score compared to group 3. At 120 and 180 minutes no difference between the groups was observed. No significant major complications were observed in all 3 groups. CONCLUSION: Penile block and caudal block provide similar pain scores and painless postoperative periods after circumcision under general anesthesia. Intravenous paracetamol is insufficient at the early postoperative period. The three procedures were shown to be safe for analgesia following circumcision.

RESUMO

PURPOSE: To evaluate the long-term outcomes of artificial urinary sphincter (AUS) implantation and to report the complication rates, including mechanical failure, erosion, and infection. MATERIALS AND METHODS: From June 1990 to May 2011, AUS (AMS 800) implantations were performed in 56 adult males by one surgeon. Various demographic and preoperative variables, surgical variables, and postoperative outcomes, including success and complication rates with a median follow-up of 96 months, were recorded retrospectively. RESULTS: The mean age of the patients at the time of AUS implantation was 61.8 (±14.2) years. During the follow-up period, the total complication rate was 41.1% (23 patients). The incidence of complications was significantly lower during the follow-up period after 48 months (p<0.05). Kaplan-Meier analysis revealed that 5- and 10-year failure-free rates were 50.3% and 45.2%, respectively. CONCLUSIONS: Long-term durability and functional outcomes are achievable for the AMS 800, but there are appreciable complication rates for erosion, mechanical failure, and infection of up to 30%.

RESUMO

The recent reports on the treatment of azoospermia patients, in which spermatozoa could not be traced in their testes, are focused more on the potential use of adult stem cells, like mesenchymal stem cells (MSCs). The aim of this study was to demonstrate the potential use of MSCs derived from adipose tissue in the treatment of azoospermia using rat disease models. After busulfan application, the rats (n = 20) were injected with the GFP(+) MSCs into left rete testes. After 12 weeks, the testes with cell injection (right testes) were compared to control (left testes) after dimensional and immunohistochemical analyses. Testes treated with MSCs appeared morphologically normal, but they were atrophic in rats without stem cell treatment, in which the seminiferous tubules were empty. Spermatogenesis was detected, not in every but in some tubules of cell-treated testes. GFP(+)/VASA(+) and GFP(+)/SCP1(+) cells in testes indicated the transdifferentiation of MSCs into spermatogenetic cells in the appropriate microenvironment. Rats with cell treatment were mated to show the full recovery of spermatogenesis, and continuous generations were obtained. The expression of GFP was detected in the mesenchymal stem cells derived from adipose tissue and bone marrow and also in the sperms of offspring. In conclusion, MSCs might be studied for the same purpose in humans in future.

RESUMO

OBJECTIVE: Inconclusive results have been published in the literature regarding the relationship between free and total serum testosterone levels and prostate cancer. We investigated the relationship between total and free serum testosterone levels, testes volume, and prostate cancer in our patient population. MATERIAL AND METHODS: Total and free serum testosterone levels and serum PSA levels were recorded for 102 consecutive patients. All of the patients underwent transrectal ultrasonography-guided prostate biopsy due to an abnormal digital rectal examination finding and/or a serum PSA level of >4.0 ng/mL. All of the transrectal and testis US examinations and prostate biopsies were performed by the same radiologist. The testis length, width, and height were measured from transverse and longitudinal gray scale images, and the testis volume was calculated. RESULTS: Prostate cancer was detected in 32 of 102 patients (31.3%) who underwent prostate biopsy (prostate cancer group). The remaining patients had benign histopathological findings (prostate cancer-free group). The prostate cancer and benign histology groups were compared for age, total and free testosterone, PSA values, and testis volume. The patients with prostate cancer were found to have a higher mean age (p=0.04). There were no significant differences in serum PSA levels, free or total testosterone levels, or testis volumes between the two groups (p>0.05). A binary logistic regression analysis showed that neither free nor total testosterone was a predictor of prostate cancer (p=0.315 and p=0.213, respectively). Only age was found to be a significant risk factor for the development of prostate cancer (p=0.02). CONCLUSION: Our study failed to show a relationship between total or free serum testosterone levels, testis volume, and the risk of prostate cancer. Therefore, monitoring serum testosterone levels for prostate cancer prediction does not appear to add an advantage over PSA screening.

RESUMO

OBJECTIVES: In this study, we evaluated the analgesic efficacy and adverse effect profile of levobupivacaine in caudal and DPNB in postcircumcision pediatric patients. METHODS: Sixty boys between 2-10 years of age undergoing circumcision were enrolled. The patients were divided into two groups: Group C (n=30) and Group P (n=30) were applied caudal block or dorsal penile nerve block (DPNB), respectively. Blocks were performed before surgery as a supplement to general anesthesia with 1 mL kg(-1) 0.25% levobupivacaine. Postoperative pain and sedation scores were assessed on the 10th and 30th minutes, and hours 1-6. The number of pain free patients in the first 6 hours, the duration of analgesia, time to first analgesic administration, walking, micturition, and total paracetamol demands, and length of stay were recorded. RESULTS: Demographic data were similar between groups. The number of children who spent the first 6 hours pain-free was larger in Group C than Group P (p=0.0001). The time to first analgesic (p=0.000033) and walking (p=0.004) were longer in Group C. There were 14 patients with motor block in Group C (p=0.00007). In view of AUC, FPRS, OPS and MPOPS were significantly better in Group C on the first postoperative 6 hours. CONCLUSION: Caudal block done using levobupivacaine for postoperative pain management in circumcision is more successful than penile block, however there is a significant delay in time to first walking and as might be expected there is an increased risk of motor block.

RESUMO

INTRODUCTION: Penile metastases are rare and represent the advanced stage of the primary tumor. The patients usually have a history of a previously diagnosed malignancy and when metastasis to penis occurs, the most common findings would be priapism, pain, and difficulty in voiding. AIM: We aimed to present a patient who had erectile dysfunction as the initial symptom of lung cancer. Besides the unusual clinical presentation, the sonographic and magnetic resonance imaging (MRI) findings of the penile metastasis were also not typical. METHODS: A 57-year-old man with erectile dysfunction was admitted to the Department of Urology. On physical examination, there was a rigid, smooth, immobile, and painless mass at the base of the corpora cavernosa. Ultrasonography and MRI were performed in order to delineate the nature of the lesion. RESULTS: Radiological findings could not lead to a certain diagnosis and the lesion could not be resected completely during the surgery. Therefore, biopsy of the corpus cavernosum penis was performed. The histopathological diagnosis was metastatic malignant epithelial tumor consistent with nonsmall cell carcinoma. Further investigations revealed a metastatic lung cancer. CONCLUSIONS: Penile metastasis may rarely be the initial presentation of a malignancy and erectile dysfunction may be a seldom symptom.

RESUMO

PURPOSE: To analyze the rate of incidental renal carcinoma in patients with no upper urinary tract symptoms (UUTS) or hematuria depending on the sonography reports and medical records of the patients and to determine whether there is a need for routine US screening for RCC. MATERIALS AND METHODS: We reviewed the reports of 18.686 consecutive urinary US examinations performed in our department between March 1995 and February 2008. A total of 18.203 urinary US examinations formed the study group. Patients with UUTS, patients with presumed diagnosis of or previously diagnosed renal masses, and patients with hematuria were excluded. RESULTS: There were 11,654 male and 6,549 female patients with a mean age of 55 years. Ultrasonography revealed incidental solid renal masses in 0.44% of the patients. Seven of the 81 patients with incidentally detected renal masses could not be followed up. Thirty-eight of the remaining 74 patients had masses that were proved to be benign with other imaging techniques. Thirty-six of the 74 patients with preoperative diagnosis of renal tumor underwent surgery, and the histopathological diagnosis was renal cell carcinoma in all patients. One patient expired in the postoperative 18th month due to the progression of the metastatic disease. The rest of the patients with malignant renal tumor are disease free and are still under follow-up. CONCLUSION: The rate of incidental renal cancer in patients without UUTS is found to be 0.20%. We believe that scanning for incidental renal masses is not obligatory except for the patients with symptoms suggestive of renal carcinoma.

RESUMO

Neoplasms arising within urethral diverticula are rare. It is important to know if a diverticulum is filled by tumor, but traditional diagnostic methods, such as voiding cystourethrography, cannot detect a tumor or diverticulum, as in our case. We report an unusual case of leiomyoma developing in a female urethra diverticulum and review the literature.

RESUMO

OBJECTIVES: Hydronephrosis is a common finding in patients with bladder cancer. This study aims at an analysis of the association between hydronephrosis, pathologic characteristics of bladder cancer and cancer-specific survival rate after radical cystectomy. METHODS: Clinical data of 241 patients who underwent radical cystectomy between 1990 and 2007 for invasive bladder cancer were analyzed retrospectively. The significance of the relation between the clinical and pathological findings were determined by the chi(2) test. The Kaplan-Meier test was used for the estimation of disease-specific survival obtained according to hydronephrosis, and the differences were examined by the log-rank test. Multivariate analysis was performed by the Cox regression model. RESULTS: Of 241 patients, 39 (16.2%) had unilateral and 13 (5.4%) bilateral hydronephrosis. Five-year cancer-specific survival rates were reported as 63.4% in non-hydronephrotic and 11.57% in hydronephrotic patients (log-rank test, p < 0.001). The presence of hydronephrosis was associated with advanced pT stage, higher tumor grade and lymph node metastases (p < 0.001, p < 0.001 and p < 0.001, respectively). Multivariate analysis showed that hydronephrosis is an important factor directly affecting cancer-specific survival (0.0264). CONCLUSIONS: The presence of hydronephrosis prior to radical cystectomy is a significant prognostic parameter, associated with poor cancer-specific survival and advanced disease stage.
