Present study showed that more than half of the children with myelodysplasia had normal UUT function even with a DLPP of 40 cm H O and over. Thus, DLPP, is not the sole decision making parameter to rely for more invasive therapies in children with myelodysplasia. On the other hand, a DLPP cut-off value of 20 cm H O showed a higher sensitivity to predict UUT damage instead of 40 cm H O. Neurourol. Urodynam. 36:759-763, 2017. © 2016 Wiley Periodicals, Inc.

Background Angiotensin‐converting enzyme 2 and transmembrane protease serine 2 are critical factors of virus transmission. Expression of angiotensin‐converting enzyme 2 is highest in testes, and testicular function and testosterone levels were affected by coronavirus disease 2019. Low testosterone levels are related to infections, especially respiratory tract infections, and could worsen clinical conditions by exacerbating cytokine storms and increasing pro‐inflammatory cytokines. Objectives We aimed to evaluate the acute and chronic effects of coronavirus disease 2019 on gonadal functions. Our second aim was to detect the relationship between free testosterone levels and disease prognosis and determine the impact of low‐free testosterone on admission to the intensive care unit. Methods Eighty‐one patients with reverse‐transcription polymerase chain reaction‐confirmed coronavirus disease 2019 were enrolled. Twenty‐nine patients were assessed again for 6 months post‐coronavirus disease 2019 follow‐up, and seven of them had a semen analysis. Serum follicle‐stimulating hormone, luteinizing hormone, sex hormone‐binding globulin, and total testosterone levels were measured. Results In this observational study, 71.6% (n = 58) of patients had low free testosterone levels at baseline, in which 69% were considered secondary hypogonadism. A longer length of hospitalization and increased inflammatory markers (d‐dimer, high‐sensitive C‐reactive protein, and procalcitonin) were detected in the low‐free testosterone group. Follicle‐stimulating hormone, total, free, and bioavailable testosterone levels were lower in patients who required admission to the intensive care unit. Free testosterone levels were inversely correlated with the length of hospitalization and prognostic disease factors. Oligozoospermia and impaired progressive motility were present in 42.8% (3/7) of the patients. In 6 months post‐coronavirus disease 2019 follow‐up, out of 29 patients, 48.2% still had low testosterone levels. Conclusion A high rate of hypogonadism (71.6%) was found, especially secondary hypogonadism, and about half of the patients had hypogonadism in the sixth months' follow‐up. Low free testosterone levels were correlated with inflammatory parameters, and it is related to the intensive care unit admission. Studies with long‐term follow‐up data in larger groups are needed to determine persistent hypogonadism and impaired spermatogenesis.

Pediatric OAB patients with high 6 months SS have a higher incidence of additional upper urinary tract pathology. Those with low pre-treatment SS require fewer laboratory tests and other assessments. The SS tool can reduce the number of urodynamics evaluations, and other tests required to diagnose renal damage in children with OAB.

Objective To compare the clinically significant prostate cancer (csPC)‐detecting results of transperineal and transrectal targeted biopsy (TPTB and TRTB, respectively) by performing matching analysis. Patients and Methods This study has used the PC and prostate biopsy database from the Turkish Urooncology Association. A total of 1143 patients with Prostate Imaging–Reporting and Data System (PI‐RADS) with ≥3 lesions on multiparametric magnetic resonance imaging (mpMRI) and who had received a software‐guided transperineal/transrectal MRI/transrectal ultrasound (TRUS) fusion prostate biopsy with concomitant standard systematic 12‐core biopsy were included in this study. csPC detection rates of the TP and TR approaches were compared following Mahalanobis distance matching within propensity score caliper method. The following four variables were selected as covariates for the matching procedure: age, digital rectal examination findings, PSA density, and the index lesion PI‐RADS score. Results The matched sample included 508 TR and 276 TP patients. In both the TP and the TR groups, targeted biopsy was superior to systematic biopsy in detecting csPC (27.5% vs. 24.6%, p < 0.001 and 19.5% vs. 16.3%, p < 0.0001, respectively). Both TPTB and TP systematic biopsy was found to be superior to TRTB and TR systematic biopsy in terms of csPC detection (27.5% vs. 19.5%, p = 0.012 and 24.6% vs. 16.3%, p = 0.006). In patients with an anterior index lesion, an apical index lesion, and a larger prostate, the superiority of TPTB to TRTB was found to be more prominent in terms of csPC detection (37.8% vs. 18.3%, p = 0.044; 34.6% vs. 14.7%, p = 0.002; and 25% vs. 5.1%, p = 0.033, respectively). Conclusion Targeted biopsy was found to be superior to systematic biopsy in detecting csPC in both the TP and the TR approaches. The TP approach is preferred because of its clear superiority in detecting csPC in targeted biopsy, especially in patients with anterior and apical lesions and with larger prostates.

Introduction: Since 2012 Elmed has been working on a robot specifically designed for flexible ureteroscopy. After the first version of Avicenna Roboflex, a second version was developed in 2015, with significant changes especially in the irrigation system. We consider mandatory for the endourologist that works with the Avicenna Roboflex be aware of the functioning of the irrigation system. Materials and Methods: We connected a container to the pump’s irrigation system and measured the quantity of saline per second delivered by each speed setting, with/without the flush in five different modalities: pump on its own, pump with ureteroscope, with two laser fibers, with 1.9 Fr basket, and with a Terumo guidewire. Results: The highest mean flow-rates were observed in the 200- micrometer laser fiber, after the pump on its own. Median flowrates for all speed settings were significantly higher for the pump on its own than for the URS in both flushed and nonflushed modes (p = 0.045, p = 0.039 respectively). There was no statistically significant difference in median flow-rates between the guide wire and basket in all of the speed settings (p = 0.932 and p = 0.977). For both laser fibers there was no statistically significant difference between the median flow rate on both nonflush and flush modes. (p = 0.590 & p = 0.590). There was a linear correlation between the speed setting and the increase measured with the flush-option for pump only measurements (r = 0.602, p = 0.038). There was no statistically significant difference between laser fibers and the pump on its own on the increase of flow rate with flush mode. (p = 0.443 for the 272- micrometer fiber and p = 0.219 for the 200-micrometer fiber). Conclusion: The irrigation system of the new Avicenna Roboflex is optimized compared to the previous version. However other more complex studies concerning the live flow/pressure relationship are needed before firm conclusions can be made.
