RESUMO
OBJECTIVES: Ureteroscopic lithotripsy and extracorporeal shock wave lithotripsy methods are commonly used in the treatment of proximal ureteral stones. There are no adequate studies showing which method is more effective in children. In our study, we aimed to evaluate and compare the efficacy of two treatment methods, commonly used for proximal ureteral stones in children. METHODS: A total of 78 patients who underwent ureteroscopic lithotripsy (n = 38) and extracorporeal shock wave lithotripsy (n = 40) due to stones located in the proximal ureter between 2010 and 2021 were included in the study. Demographic data, clinical characteristics, and treatment outcomes were retrospectively analyzed. Kolmogorov-Smirnov, Chi-square, and Mann-Whitney U tests were used for statistical analysis. RESULTS: There was no statistical difference between the demographic characteristics of the groups, except for the mean age values (p = 0.008). A statistically significant difference was found in favor of the extracorporeal shock wave lithotripsy group in terms of stone-free rates after the first intervention, complication rates requiring intervention, re-intervention rates, and the average number of anesthesia sessions per patient until stone-free status (p = 0.043, p = 0.009, p = 0.017, and p < 0.001, respectively). CONCLUSIONS: The results of this retrospective study suggest that extracorporeal shock wave lithotripsy is the primary treatment option for single, non-complicated proximal ureteral stones.

BACKGROUND: The optimal management of lower pole kidney (LPK) stones in children is controversial. The aim of this study was to determine the outcomes of children with asymptomatic isolated LPK stones smaller than 10 mm during follow-up. METHODS: A total of 242 patients with 284 stones presenting at our institution between June 2004 and December 2014 with an asymptomatic, single LPK stone with a diameter of <10 mm were enrolled in the study. All children were assigned to receive first-line therapy and then categorized according to the need for medical intervention. Age, gender, stone laterality, stone size and type, associated urinary tract problems, and uncontrolled metabolic status were assessed as predictive factors of medical treatment for small (<10 mm) asymptomatic LPK stones. Stone-free rates were compared between interventions. RESULTS: The mean age and mean stone size were 9.4 ± 1.9 years and 7.4 ± 0.6 mm at admission, respectively. Stone progression rate was 61.2%, and the mean time for intervention was 19.2 ± 4.6 months. Flexible ureterorenoscopy (n = 68) or micro-percutaneous nephrolithotomy (n = 4) were performed for 72 stones (25.4%; group 1), and extracorporeal shock wave lithotripsy was performed for 102 stones (35.9%; group 2). The stone-free rates were 81.8 and 79.3% in group 1 and 2, respectively (p > 0.05). The remaining asymptomatic stones (110, 38.8%; group 3) were managed by continued observation, and at the end of the observation time (mean 40.8 ± 20.8 months) the spontaneous passage rate was 9.1% in this group. In the multivariate analysis, stone size of >7 mm, concurrent renal anomalies, and stones composed of magnesium ammonium phosphate (struvite) and cystine were statistically significant predictors of the need for intervention. CONCLUSIONS: Children with stones larger than 7 mm, renal anomalies, or stones composed of metabolically active cystine or struvite are more likely to require intervention, and those with asymptomatic LPK stones smaller than 10 mm can be managed by continued observation.

BACKGROUND: Echinococcosis is a parasitic disease caused by Echinocccus granulosus and Echinococcus multilocularis and declared a neglected tropical disease by the World Health Organization. The disease is a significant cause of morbidity and mortality, especially in India, Australia, China, Turkey, South America, the Middle East, and Eastern European countries. Bibliometric analysis is a popular research trend that gains the advantage of evaluating all the studies about one specific topic and emphasizing the importance and place of the subject in the literature. With this study, we aim to evaluate all the global published literature in the Web of Science core collection database about urinary tract echinococcosis between 1945 and 2024. METHODS: All documents indexed in the Web of Science core collection database between 1945 and 2024 were scanned on March 29, 2024. VOSviewer program 1.6.20 and MS Office Excel 2017 programs were used for forward analysis. RESULTS: 152 documents were obtained, 102 of which were indexed in SCI-Expanded journals. Turkey (21.71%) was the leading country in terms of the total number of documents, followed by India (21.05%), but citations of Indian publications were higher (21.77%). Spain was in the first rank in terms of average citations per document (19.33). Most of the documents were original articles (78.29%). Okan Akhan was the most prolific author, with three documents. The most-cited document was conducted in 1997 by Angulo et al. and received 74 citations. With seven publications, Urology Case Reports was the journal that published the most documents on urinary tract echinococcosis. CONCLUSIONS: Evaluating the studies on urinary system echinococcosis with bibliometric analysis, it is understood that although the number of studies has gradually increased over the years, they are still less than expected. We recommend that more studies be conducted to determine the true prevalence of echinococcosis and ensure more effective management of the disease, especially in countries where it is endemic.

Background In this study, we aim to present the experience of a tertiary center regarding penile epidermoid cysts over 15 years. Methodology Patient files of those who underwent surgical excision for penile epidermoid cysts between 2005 and 2019 were reviewed retrospectively. The demographics, clinical characteristics, etiological factors, cyst features, surgical techniques, complications, and follow-up data were analyzed. Results In total, 24 penile epidermoid cysts were excised in 21 boys. The median age at the time of surgery was 52 (15-204) months. The median duration between previous surgery and cyst excision was 40 (1-180) months. In total, 11 cases had a history of circumcision, and 10 had undergone hypospadias surgery. There was no significant difference between these two etiologic groups (p > 0.05). The main symptom was an asymptomatic penile mass. The average cyst size was 9.4 ± 6.7 mm. All cysts were completely excised with incisions made over old scars, except one. No complications were observed during a median follow-up period of 50 (12-120) months, and only one recurrence was noted. Conclusions Acquired penile epidermoid cysts may present as an early or late complication after penile surgery. Complete excision with an incision along the existing scars seems to be an effective solution for preventing new scars.
RESUMO
PURPOSE: Perineal electromyography (EMG) is a crucial part of urodynamic studies. Many researchers focused on the standardization of techniques in urodynamics, but no study has yet evaluated the differences with various reference electrode placements. The aim of this study was to determine the optimal placement of the reference electrode for recording pelvic floor activity in urodynamic studies. METHODS: Children over 6 years of age without anatomic or neurological abnormalities were invited to participate in the study. Four reference electrodes were placed on the right kneecap, the inner surface of the right inner thigh, the right anterior iliac spine (AIS), and the skin over the left gluteal muscles for simultaneous recording. The EMG signal formed by pelvic contraction during forceful straining was recorded both in the supine and sitting positions. The root mean square (RMS) value of each muscle contraction signal was calculated. RESULTS: Twenty-one participants (10 boys and 11 girls) were included. The mean age was 10.19±3.20 years. The highest RMS values were obtained with the reference electrode on the thigh in the supine position and the AIS in the sitting position. Significant differences were found between the mean RMS values of the knee and other locations of reference electrodes in the supine position, as well as between mean RMS values in all regions except the thigh and gluteus in the sitting position. The minimum mean RMS values in both positions were obtained with the reference electrode on the knee. CONCLUSION: During urodynamic studies, reference electrodes shall be placed on AIS in the sitting and on the inner thigh in the supine position. The knee is not a suitable option for reference electrode placement. This information may help improve EMG recordings in the evaluation of pelvic floor muscles.
RESUMO
PURPOSE: To discuss whether concealed penis after circumcision lowers perimeatal urethral and glanular sulcus uropathogenic bacterial colonization in healthy boys with no urinary tract problems and prevents attacks of febrile urinary tract infections in non-healthy boys with defined urinary tract abnormalities. Materials and Methods: This case-control study was conducted in Ibn-i Sina Hospital and retrospectively collected data of 471 boys were analyzed. All patients were scanned for any urinary tract abnormality and those with any defined abnormalities were classified as non-healthy group. (123 patients) Non-healthy patients were divided into two subgroups as concealed (n:31) and non-concealed (n:92) penis after circumcision. Healthy patients with no urinary problems were divided into three groups as circumcised without concealed penis (n:144), with concealed penis after circumcision (n:104) and uncircumcised control group (n:100). Bacterial cultures were obtained from both periurethral meatal and glanular sulcus areas by adhering strictly to the rules of obtaining bacterial culture to avoid false-positive or negative culture results. Also only uropathogenic bacterias were evaluated, irrelevant results were excluded. Results: Mean age was similar in healthy population. Comparison of three groups showed that there was a significant difference in both cultures.(P = .026 for periurethral meatal region, P = .039 for glanular sulcus region) In post hoc analysis, non-concealed group had a lower rate of culture positivity in both areas compared to other groups. Mean age was also similar in non-healthy population. Mean follow-up period was 18.2 months. Patients with concealed penis after circumcision had a significantly higher number of febrile UTI attacks (20 attacks in 8 patients vs 7 attacks in 5 patients) compared to non-concealed group. (P = .019) All febrile UTI attacks except one in this group occurred below the age of 12 months. A total of 10 patients in both healthy and non-healthy groups had postoperative hemorrhage after circumcision and only 1 patient had a wound infection. Conclusion: Concealed penis after circumcision does not lower perimeatal urethral and glanular sulcus uropathogenic bacterial colonization in healthy patients and does not protect unhealthy patients from febrile urinary tract infection attacks. If circumcision is planned, concealed penis should be avoided and also parents should be informed about the possible risks due to concealed penis before the procedure, particularly in patients with urinary tract abnormalities.

INTRODUCTION: Percutaneous nephrolithotomy (PNL) is the primary treatment modality for management of staghorn stones. PNL in supine position has important advantages over prone positon. However, studies comparing prone and supine positions for PNL in staghorn stone patients have conflicting results, and the aim of the current study was to compare prone and supine positions for PNL in staghorn stone cases. PATIENTS AND METHODS: Data of patients underwent PNL for staghorn stones in supine or prone position by a single urologist were collected prospectively. The supine and prone position groups were compared for stone free rate (SFR) and complication rates. All patients were evaluated with NCCT for evaluation of SFR. Chi-square test was used to compare categorical variables and Student t test was applied for continuous variables of the treatment groups. RESULTS: The groups were similar for demographic and stone-related characteristics. Multi-caliceal and intercostal access was more common in prone position. Operation duration was significantly shorter and hemoglobin drop was significantly less in supine group. SFR was 64.1 and 60.4% in the supine and prone groups, respectively (p = 0.72). Complication rates were similar in the two groups but Clavien III complications were observed in two patients in the prone group. CONCLUSIONS: PNL in supine position is an effective treatment for management of staghorn stones. The need for multi-caliceal and intercostal puncture is less when combined with retrograde intrarenal surgery. PNL in supine position should be considered as primary treatment option in staghorn stone cases.

PURPOSE: To date, laparoscopy has gradually become the gold standard for treatment of non-palpable testicles (NPT) with different success and complication rates. In this study, we aimed to evaluate outcomes of laparoscopic approaches for NPT. MATERIALS AND METHODS: We reviewed data of 82 consecutive patients who underwent laparoscopic treatment for unilateral NPT at two institutions by two high volume surgeons from 2004 January to 2014 December. Laparoscopic-assisted orchidopexy (LAO) and two-stage Fowler-Stephens technique (FST) was performed for 45 and 37 patients, respectively. Age (at surgery), follow-up time, laterality of testes, and postoperative complications were analyzed. Modified Clavien classification system (MCCS) was used for evaluating complications. RESULTS: The median age (at surgery) and median follow-up time were 18 (range: 6-56) and 60 (range: 9-130) months, respectively. Overall success rate for two laparoscopy techniques was 87.8% during the maximal follow-up time. We observed wound infection in two, hematoma in one, testicular atrophy in five, testicular re-ascending in two patients at follow-up period. There was no statistical difference between two laparoscopic techniques for grade I (five vs. two patients, p = 0.14) and grade IIIb MCCS complications (five vs. two patients, p = 0.44). CONCLUSION: Our results have shown that two laparoscopic approaches have low complication rates.
