| 1 | Testicular torsion in undescended testis:A persistent challenge显示文摘Objective:To evaluate the management and outcomes of patients who presented with torsion of an undescended testis and review the reported series in the literature.Methods:The case records of 13 patients operated for testicular torsion involving undescended testis were retrospectively reviewed.The medical records included age at presentation,medical history,physical examination,operative findings and the results of follow-up.The diagnosis of torsion of undescended testis was made clinically and confirmed by inguinal exploration.Results:In six cases the testis was preserved and orchiopexy was performed,while in seven cases orchidectomy was performed due to testicular gangrene in six patients and testicular tumor discovered peroperatively in one case.Mean duration of symptoms at time of surgery in the orchiopexy group was 6.5 h and in the orchidectomy group was 21.2 h.From six patients treated by orchiopexy,two patients suffered from testicular atrophy at a mean of 24 months.Conclusion:Testicular torsion in undescended testis is still diagnosed with delay which may affect testicular salvage.The importance of examination of external genital organs is highlighted which should be routinely included by emergency physicians in physical examination for abdominal or groin pain. | Sahbi Naouar Salem Braiek Rafik El Kamel | 2017 | Asian Journal of Urology2017，4，2： | 5 |
| 2 | Systematic design method for PI controller with Virtual Resistor-based Active Damping of LCL filter显示文摘The Virtual Resistor based Active Damping(VR-AD) is widely employed in converters connected to the grid via LCL filters in order to mitigate the inherent resonance of the filters. Nevertheless, in digitally controlled systems, the PWM and the calculating delays modify the system characteristics in terms of frequency and phase, thus destabilizing the system and degrading the VR-AD performances, mainly in low switching frequencies. Moreover, the stability of the system is greatly affected under weak grid operation characterized by large grid impedance variation. This paper solves these problems by proposing a systematic, robust and optimized design procedure of voltage oriented PI control(VOC) with VRAD. The considered design procedure ensures robust control(sufficient stability margins) and high quality of grid current(reduced steady-state error and minimized THD value) despite the negative impact of digital time delay, grid impedance variation and filter parameters change. Simulation and experimental results are presented to show robustness and efficiency of the suggested design procedure. | Marwa Ben Said-Romdhane Mohmed Wissem Naouar Ilhem Slama-Belkhodja | 2018 | Global Energy Interconnection2018，1，3： | 4 |
