    © 2023 Wiley Periodicals LLC.Aim: The aim of the study is to compare the intra- and inter-observer interpretations of the same uroflowmetry study at two different times. Materials and Methods: Two-hundred children with a voided volume of 50% above the expected bladder capacity were included. All traces were asked to be evaluated by 11 observers two times in a time span of 1 month. These observers consist of pediatric urologists (n = 2), pediatric urology fellows (n = 2), urology residents (n = 5), and certified urodynamics nurses (n = 2). Each uroflowmetry was asked to be assessed for three domains: voided volume (VV), detrusor sphincter dyssynergia (DSD), and flow curve pattern (FCP). Results: Of the 200 patients with a median age of 10 (4–18) years, 128 (64%) were girls and 72 (36%) boys. The maximum flow rate and the median voided volume were found to be 20 (4–61) mL/s and 232 (116–781) mL. The Fleiss\" kappa coefficient of VV, DSD, and FCP in the first assessment was 0.510, 0.501, and 0.346. In the second assessment, κ values were 0.530, 0.422, and 0.373. The best-agreed findings were similar at both times. These were found to be low VV (0.602 and 0.626) and intermittent pattern (0.500 and 0.553). Interpreters were found to have a statistically significant difference in agreement with their own interpretation at different times. Conclusion: Both inter- and intra-observer reliability of the agreement point out the problem in the standardization of uroflowmetry. Inter- and intra-observer reliability of uroflowmetry interpretation can be increased by defining precise numbers and numerical algorithms.

    (2023-01-01) ŞEKERCİ, ÇAĞRI AKIN; YÜCEL, SELÇUK; ÇAM, HAYDAR KAMİL; Ali Üncü Y., ŞEKERCİ Ç. A., YÜCEL S., Sircan-Kucuksayan A., ÇAM H. K., Savaş M., Yıldırım A., Ağras K., Baykara M., CANPOLAT M.
    © 2023 Elsevier Inc.Objective: To develop a near-infrared (NIR) spectroscopy device to diagnose testicular torsion with high sensitivity and specificity. Specifically, we aim to investigate the differentiation between testicular torsion from other pathologies such as orchidoepididymitis, varicocele, and hydrocele. Methods: Two LEDs with wavelengths of 660 nm and 940 nm were used as light sources in the device. Each wavelength was sent to the testicle successively, and a photodiode detected back-reflected diffuse light. The ratio of the light intensities of 660 nm and 940 nm was used as a diagnostic parameter. A multi-center clinical trial was performed in 5 different hospitals. Results: In total, 62 patients in urology clinics with acute testicular pain have been recruited for the study. The developed NIR spectroscopy correctly defined all 8 testicular torsion cases. Besides, 3 orchidoepididymitis, 1 varicocele, and 3 hydrocele cases were correctly distinguished from testicular torsion. Only 1 hydrocele case was misdiagnosed as torsion. The range of the ratio was between 0.14 and 1.16 overall measurements. The ratio varied between 0.14 and 0.3 for the testicle with torsion. The ratio was between 0.49 and 1.16 for the normal testicle and testicle with other pathologies mentioned above. Conclusion: We have chosen the threshold ratio of 0.4 to differentiate between the normal and torsion testis and diagnosed all the torsion cases among all normal and other pathologies. The developed optical device to diagnose testicular torsion is inexpensive, user-friendly, and works based on objective criteria with high sensitivity and specificity in real time.

    The association of urinary BDNF, ATP, and MMP-2 with bladder compliance in children with myelodysplasia
    (2023-01-01) ŞEKERCİ, ÇAĞRI AKIN; KÜTÜKOĞLU, MEHMET UMUT; YÜCEL, SELÇUK; TARCAN, TUFAN; ŞEKERCİ Ç. A., KÜTÜKOĞLU M. U., Basok B. I., Fidan M., ÇAM S., YÜCEL S., TARCAN T.
    Aim: The purpose of our study was to evaluate the relationship of urinary brain-derived neurotrophic factor (BDNF), adenosine triphosphate (ATP), matrix metallopreteinase-2 (MMP-2) with urodynamic findings and upper urinary tract deterioration (UUTD) in children with myelodysplasia. Materials and Methods: Children with myelodysplasia evaluated in outpatient clinic between 2022 and 2023 were included. All patients underwent urinary ultrasonography, voiding cystourethrography, urodynamics, and DMSA scintigraphy. Urine samples were collected before urodynamics. Control urine was collected from 10 healthy children. Urinary biomarker values of patients and controls were compared, and subgroup analysis was performed. Results: The median age of 40 children (26 girls) included in the study was 108 (8–216) months, and the control group (six girls) was 120 (60–154) (p = 0.981). Urinary BDNF, MMP-2, and ATP were found to be significantly higher in children with myelodysplasia compared to the control (p = 0.007, p = 0.027, p = 0.014, respectively). The three biomarker values were similar in children with bladder compliance below or above 10 cmH2O/mL (p = 0.750, p = 0.844, p = 0.575). No difference was found in terms of UUTD in all three biomarkers (p = 0.387, p = 0.892, p = 0.705). A negative correlation was found between urinary ATP and compliance (p < 0.05). Conclusion: In this study, all three biomarkers were found to be higher in children with myelodysplasia than in controls. There was a negative correlation between urinary ATP and compliance. Urinary biomarkers may contribute the follow-up of children with neurogenic lower urinary tract deterioration in future with their noninvasive features. However, the lack of standardization and the inability to reliably predict risky groups are important shortcomings of urinary biomarkers.

    Primer monosemptomatik enürezis nokturnası olan çocuklarda desmopressin tedavisine tam yanıtın prediktif faktörleri
    (2023-10-04) ŞEKERCİ, ÇAĞRI AKIN; TARCAN, TUFAN; YÜCEL, SELÇUK; Özgür G., Şekerci Ç. A., Tanıdır Y., Tarcan T., Yücel S.
    AMAÇ: Primer monosemptomatik enürezis nokturna (PMEN), pediatrik ürolojide sık görülen bir problemdir ve medikal tedavide ilk tercih desmopressindir. Bu çalışmada, desmopressine tam yanıt alınan PMEN'li çocuklarda prediktif faktörleri ve desmopressinin idrar elektrolit düzeyleri (sodyum, potasyum ve kalsiyum) üzerindeki etkisini değerlendirmeyi amaçladık. MATERYAL-METOD: Çalışmaya çocuk ürolojisi polikliniğine başvurup PMEN tanısı alan ve desmopressin tedavisi başlanan çocuklar dahil edildi. Gündüz semptomları olan veya sekonder enürezisi bulunan çocuklar çalışmaya alınmadı. Hastalar fizik muayene, idrar tahlili, semptom skoru ve işeme günlüğü ile değerlendirildi. Tüm hastalara 120 mcg desmopressin başlandı. Hastalardan tedavi öncesinde, tedavi sonrası ise 1. ve 3. aylarda elektrolit değerlendirmesi için 24 saatlik idrar toplandı. Üçüncü aydaki semptomlarına göre tedaviye tam yanıt veren grup ve diğer (tedaviye dirençli veya kısmi yanıtlı) grup olarak hastalar ikiye ayrıldı. Hastaların tedavi öncesi ve tedavi sonrası elektrolit değerleri karşılaştırıldı ve tam yanıtlı grupta yanıtı öngörebilecek olası prediktif faktörler değerlendirildi. BULGULAR: Çalışmaya 34 çocuk (23 erkek, 11 kız) dahil edildi. Ortanca yaş 8 (5-15) idi. Tedavi öncesi ve sonrasındaki (1. ve 3. ay) idrar dansitesi, 24 saatlik idrar sodyum, potasyum ve kalsiyum değerleri arasında fark yoktu (p=0,432, 0,822, 0,970, 0,970, sırasıyla). Cinsiyet, bir aydaki ıslak gece sayısı ve bir gecede olan idrar kaçırma sayısı desmopressine tam yanıtı öngören faktörler olarak bulundu (p=0,015, 0,022, p=0,001, sırasıyla) (Tablo 1). Yaşın, aile öyküsünün, işeme günlüğündeki mesane kapasitesi/beklenen mesane kapasitesinin ve tedavi öncesi idrar sodyum seviyesinin tam yanıtı öngörme üzerinde etkisinin olmadığı gösterildi (p=0,230, p=0,547, p=0,763, p=0.060, sırasıyla) (Tablo 1). SONUÇ: PMEN'li çocuklarda erkek cinsiyet olması, bir ayda çok sayıda ıslak gece olması ve bir gecede çoklu idrar kaçırma olması desmopressin tedavisine tam yanıt alınmasında olumsuz faktörler olarak bulundu.

    Normal glanular and meatal measurements in boys and men
    (2023-01-01) ŞEKERCİ, ÇAĞRI AKIN; ÖZKAN, ONUR CAN; GENÇ, YUNUS EMRE; TANIDIR, YILÖREN; TARCAN, TUFAN; YÜCEL, SELÇUK; ŞEKERCİ Ç. A., ÖZKAN O. C., Sahak M. Y., GENÇ Y. E., TANIDIR Y., TARCAN T., YÜCEL S.
    Objective: To determine the normal vertical urethral meatus length (ML), maximum glanular width (MGW), the glanular seam length (between the lowest edge of urethral meatus and the glans closure line corona) (GSL) and GSL/ML ratio in all age groups. Materials and Methods: Consecutive patients presented to urology and pediatric urology outpatient clinics were included in the study. Penile abnormalities, known endocrinological disorders, history of penile/urethral surgery were excluded. MGW, ML, and GSL were measured with a caliper. Glanular and meatal measurements were compared according to ages. Results: A total of 1398 boys and men (380 (27.18%) prepubertal (1-12), 203 (14.52%) adolescent (13-19), and 815 (58.30%) postpubertal (19-93)) with a median age of 31 years (range: 1-93) were included in the study. In consecutive age groups, ML and GSL gradually increased and became steady between 16-19 & 20-30 age groups and 10-12 & 13-15 age groups, respectively. On the other hand, MGW gradually increased until 20 years of age and became steady at median of 35 mm over 20 years of age. Another interesting finding was a rather stable GSL/ML ratio in all age groups. Pairwise comparison of different age groups seemed to be similar and suggests a fixed ratio of 1.33 (IQR: 0.6). Conclusion: The normal glanular and meatal measurements may guide the surgeons for better cosmetic results during hypospadias repair. The GSL/ML ratio appears to be a stable measure for all ages to achieve better cosmetic results.

    A survey study on evaluation and management of nocturnal enuresis in pediatricians and family physicians
    (2023-09-01) ŞEKERCİ, ÇAĞRI AKIN; KÜTÜKOĞLU, MEHMET UMUT; DÖRÜCÜ, DOĞANCAN; TANIDIR, YILÖREN; ÇAM, HAYDAR KAMİL; TARCAN, TUFAN; YÜCEL, SELÇUK; Şekerci Ç. A., Kütükoğlu M. U., Dörücü D., Ergün R., Tanıdır Y., Çam H. K., Tarcan T., Yücel S.
    Objective:Nocturnal enuresis (NE) is one of the most common disorders in pediatric urology, and patients often turn to family physicians (FP) and pediatricians (P) initially. The aim of this study was to understand the awareness, self-confidence and suggestions of physicians regarding the management of NE.Materials and Methods:In this study, 360 FP and family medicine residents (FMR), as well as 280 P and pediatrics residents (PR), were contacted through a cellular phone texting system. A simple multiple-choice questionnaire (Surveymonkey®) consisting of 10 questions was used to gather data. The survey included questions about their experience, training, evaluation, and management of NE.Results:A total of 119 FPs and Ps (18.5%) filled the questionnaire. Thirty (25.21%) of the participants were P, 27 (22.69%) PR, 3 (2.52%) FP and 59 (49.58%) FMR. The rate of physicians who encounter at least 5 children with NE per month is 31.33%. The mean self-confidence in the management of NE was 4.5 out of 10. The self-confidence of pediatricians was significantly higher than that of PR and FMR (p<0.001, p<0.001). Most (n=78, 65.55%) of the participants stated that they received training on EN during medical faculty and 62 (52.10%) during residency. Psychological problems (89.92%), sleep disorders (78.15%), and excessive fluid intake (75.63%) were the most frequently considered factors in etiology. While most responders (75.63%) considered dietary regulation and behavioral interventions as the first-line treatment, 25.21% consult a pediatric urologist and only 1.6% recommend medical treatment.Conclusion:Although FP and P admit they had training on NE, they mostly felt incompetent to manage NE and exclusively avoided pharmacological treatment.Keywords:Children, enuresis nocturna, pediatric urology, physicians, survey

    Are voiding volumes and frequencies different in the three-day voiding diary in children with lower urinary tract dysfunction
    (2023-10-03) ŞEKERCİ, ÇAĞRI AKIN; YÜCEL, SELÇUK; TARCAN, TUFAN; Ergun R., ŞEKERCİ Ç. A., Cetin M., Sahak M. Y., YÜCEL S., TARCAN T.
    AIM: The voiding diary (VD) yields crucial insights into voiding volumes (VV), voiding frequency (VF), and management habits in children with lower urinary tract (LUT) dysfunction. It is recommended to be conducted for a minimum of 2 days. Nevertheless, certain studies have indicated similarities in voided volumes between days in a three-day VD. This study aims to compare VV and VF values across days based on bladder capacity and symptom scores. MATERIALS AND METHODS: Children who applied to the pediatric urology clinic due to LUT symptoms between 2022 and 2023 were included in the study. Retrospective evaluation was conducted on the records. Children with neurological deficits and incomplete data were excluded from the study. All children were assessed following the guidelines of ICCS and EUA and underwent a 3-day voiding diary. Mean VV and VF values of the whole group for each day were compared and subgroup analyzes were performed in terms of gender, Voiding Dysfunction Symptom Score (VDSS), bladder capacity (BC), and diagnoses. RESULTS: A total of 109 (53 girls (48.6%), 56 boys (51.4%)) children with a median age of 8 (3-17) were included in the study. 77 (70.6%) children were diagnosed with overactive bladder, 8 (7.4%) with dysfunctional voiding, and 24 (22%) with monosymptomatic enuresis nocturne. The mean VVs between days were similar in the whole group (p = 0.759). Moreover, the mean VV of the first day was similar to the average of both the first two days and the three days (p = 0.021, p = 0.490). Also, the maximum and minimum VVs were similar between days (p = 0.942, p = 0.160, respectively). In subgroup analyses based on gender, bladder capacity, and symptom score, mean VV was also found to be similar. VF values were found to be significantly different between days. There was also a difference between VF values in children with VDSS > 8.5 (p = 0.012) and BC/EBC (%) > 65 (p = 0.030). In subgroup analysis for diagnoses, mean and maximum VV and VF were similar between the groups, except for VF (p = 0.026) in OAB. CONCLUSION: While the voided volumes of children with non-neurogenic LUT dysfunctions appear to be consistent across the days of the VD, variations in VF might arise, especially among children with a VDSS of > 8.5 and normal bladder capacity. As a result, we believe that using a VD spanning at least two days could enhance diagnostic accuracy and help prevent unnecessary treatment.

    The results of three times repeated filling cystometry and pressure flow studies in children with non-neurogenic lower urinary tract dysfunction
    (2022-06-01) YÜCEL, SELÇUK; ŞEKERCİ, ÇAĞRI AKIN; TARCAN, TUFAN; TANIDIR, YILÖREN; Ergun R., ŞEKERCİ Ç. A., TANIDIR Y., Ozturk N. I., TARCAN T., YÜCEL S.
    Aim We previously reported that some urodynamic parameters change with repetitive filling in children with neurogenic lower urinary tract dysfunction (LUTD). In this study, we aimed to search if three-times repeated filling cystometries (FC) and pressure-flow studies (PFS) would change the urodynamics parameters in children with non-neurogenic LUTD. Materials and Methods All children with three repeated FC and PFS between June 2017 and December 2018 were included in the study. Urodynamic reports and charts were evaluated retrospectively. The first sensation of bladder filling (FSBF), maximum cystometric capacity (MCC), detrusor pressure at the FSBF (P-det.first.sens), maximum detrusor pressure during filling (P-det.fill.max), presence of detrusor over activity, compliance, maximum urine flow (Qmax), detrusor pressure at the maximum urine flow (PdetQmax), residual urine and presence of detrusor sphincter dyssynergy (DSD) were compared among three-times repeated urodynamic studies. Results Forty children were included in the study. 27 (67.5%) were girls and 13 (32.5%) were boys. Median age was 9 (3.4-17) years. Indications were LUTD with low grade vesicoureteral reflux in 19 (47.5%), LUTD refractory to conservative management in 13 (32.5%), urinary tract infection with LUTD in 6 (15%) and secondary enuresis in 2 (5%). P-det.first.sens, presence of DO, MCC, Qmax, PdetQmax, residual urine, flow pattern, and presence of DSD were comparable in all three repeated tests. The third FC may show decreased filling detrusor pressures and increased compliance with no change on capacity. Conclusion In children with non-neurogenic LUTD, three-times repeated FC and PFS present comparable results except FSBF, P-det.fill.max,P- and compliance at the third test.
