The synergistic effects of betanin and radiotherapy in a prostate cancer cell line: an in vitro study.

BACKGROUND: Prostate cancer is among the most common cancers in men with an increasing incidence rate. Radiation therapy (RT) is a therapeutic strategy for the management of prostate cancer after surgery; nonetheless, it has different side effects on neighboring healthy cells/tissues. Moreover, radioresistance has been an increasing phenomenon in the recent years. Therefore, there is an urgent need for the introduction of a safe and effective radiosensitizing agent. Accordingly, the recent trend in the development of novel drugs is accompanied by a push toward natural compounds. Our study evaluated the effects of betanin combined with RT as a potential radiosensitizing agent in the PC-3 cell line. METHODS AND RESULTS: MTT assay was utilized to determine the growth inhibitory impact of betanin. The possible synergistic effect was evaluated with CompuSyn software upon Trypan blue exclusion test. Apoptosis-related gene expression was evaluated via Real-time PCR and the protein expression of P21 was determined using western blotting. A synergistic anticancer effect with an optimal combination index of 0.61 was achieved by treating PC-3 cells with betanin and RT. The results pointed out that betanin synergistically triggered RT-mediated apoptosis and cell cycle arrest through modulating gene and protein expression in comparison with each of the monotherapies. CONCLUSION: These findings shed light on the synergistic antitumor effect of betanin and RT in prostate cancer, indicating the potential use of betanin as a radiosensitizer agent.

The beneficial effect of clove essential oil and its major component, eugenol, on erectile function in diabetic rats.

Diabetic men are at a higher risk of erectile dysfunction (ED). A tropical plant, clove (Syn. Eugenia caryophyllata, Caryophyllus aromaticus L., Syzygium aromaticum (L.) Merr. & L.M. Perry) from the Myrtaceae family has displayed aphrodisiac activity. The present research aimed to investigate the impacts of clove essential oil (CEO) and the ingredient of CEO, eugenol (E) on ED in diabetic rats. We divided Sprague-Dawley rats into control and diabetic groups. Erectile function was evaluated before and after CEO and E intracavernosal injection. CEO- and E-induced relaxation responses were investigated in isolated corpus cavernosum (CC) using various inhibitors. The intracavernous administration of CEO and E restored erectile responses in diabetic rats. CEO and E induced remarkable relaxation in all groups. CEO- and E-induced relaxation responses were partially inhibited after pre-contraction with KCl. Tetraethylammonium and glibenclamide inhibited the relaxation response to CEO. Glibenclamide inhibited maximum relaxation to E. The inhibitors of nitric oxide synthase (NOS), soluble guanylyl cyclase and nifedipine did not change CEO- and E-induced relaxation responses. The current results suggest that CEO and the major compound of the essential oil, E improved diabetes-induced ED in rats, and CEO caused CC relaxation via K+ channels independently NO signalling pathway.

Antigenotoxic properties of Paliurus spina-christi Mill fruits and their active compounds.

BACKGROUND: Paliurus spina-christi Mill. (PS) fruits are widely used for different medical purposes in Turkey. Like in many medicinal herbs the studies concerning their activity, the activities of PS are also not well clarified. The aim of this study is to evaluate the antigenotoxicity of the compounds isolated and identified from the extracts of PS fruits. METHODS: The active compounds were separated, isolated, and determined by chromatographic methods and their structural elucidation was performed by Nuclear Magnetic Resonance (NMR) methods. The compounds were obtained from either ethyl acetate (EA) or n-butanol extracts. The cytotoxicities of the compounds using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and the antigenotoxic activities of the compounds using the alkaline single cell gel electrophoresis techniques (comet assay) were evaluated in Chinese hamster lung fibroblast (V79) cell lines. RESULTS: The isolated major compounds were identified as (+/-) catechins and gallocatechin from EA fraction and rutin from n-butanol fraction of PS fruits. Their chemical structures were identified by 1H-NMR, 13C-NMR, HMBC, and HMQC techniques. Half-maximal inhibitory concentration of catechins, gallocatechin, and rutin were found to be 734 µg/mL, 220 µg/mL, and 1004 µg/mL, respectively. The methanolic extract of PS (1-100 µg/mL) alone did not induce DNA single-strand breaks while catechins (1-100 µg/mL), gallocatechin (1-50 µg/mL), and rutin (1-50 µg/mL) significantly reduced H2O2-induced DNA damage. CONCLUSION: It has been suggested that PS fruits and their compounds catechins, gallocatechin and rutin may have beneficial effects in oxidative DNA damage. It seems that PS fruits may be used in protection of the disorders related to DNA damage.

Flavoxate in urogynecology: an old drug revisited.

INTRODUCTION AND HYPOTHESIS: Since its emergence in 1967, flavoxate has been used to treat several urogenital tract disorders irrespective of the etiology of the underlying disease, but the main indications have been overactive bladder and urge symptomatology. With the advances in anticholinergic drugs, its popularity has decreased in recent decades. METHODS: In this review we summarize the current status of flavoxate in urogynecological practice focusing on its historical background, mechanism of action, efficacy, clinical experiences, outcomes, side effects and tolerability. We reviewed and analyze all the data and draw the major conclusions. We searched MEDLINE and the Cochrane Library using the keyword "flavoxate", and summarized review articles, original studies and case reports published from 1970 to 2013. RESULTS AND CONCLUSION: We conclude that the minimal side effects and high tolerability of flavoxate make it worthy of consideration for the treatment of several clinical urogynecological conditions. It deserves more clinical studies to assess its efficacy as no randomized controlled trials have been performed with flavoxate during the last decade. More studies and novel drug formulations may reveal or improve its efficacy in daily practice.

Determination of chemical components of the endemic species Allium turcicum L. plant extract by LC-MS/MS and evaluation of medicinal potentials.

The Allium turcicum L. (Zuzubak) plant as a cultivated vegetable have various health benefits and consumed as a food. Due to the shortcoming evidence in literature and the importance of this plant in folk medicine, in the present study, for the first time, we evaluated the bioactive profile of components (using LC-MS/MS), cytotoxicity, anticancer, antioxidant, and antibacterial prospectives of Zuzubak methanol extract. Reported results show that the extract is rich in bioactive compounds and has anticancer activity with breast cancer cells (MCF-7), human prostate cancer cells (DU-145), and Human osteosarcoma cancer Cell lines of (IC50) in dose dependent manner in the concentration range of 31.25 µg/mL and 2000 µg/mL for 24 and 48 h. Western blotting results determined that the extract significantly suppressed the growth of U2OS, MCF-7, and DU-145 cancer cells by down expression of Ang-1 (angiogenic protein) and Beclin-1 (autophagy protein) and overexpression of Bax (a proapoptotic protein). The oxidative stress indices showed a reduction in RPE-1 and MCF-7 cells and an upsurge in U2OS and DU-145 cells. Additionally, the antimicrobial assay showed suppression of the growth of various pathogenic microorganisms in 4.00-8.00 µg/concentrations of Zuzubak extract using the microdilution method. The phytochemicals identified showed promising anticancer, antioxidant effects, and antimicrobial properties, representing a valuable herbal source for drug development studies.

Buccal mucosa graft tube urethroplasty for the treatment of bulbopenile urethral trauma accompanied with massive tissue loss due to improvised explosive device injury.

Urinary diversion with suprapubic cystostomy and delayed urethroplasty is recommended for the treatment of penetrating posterior urethral traumas. A devastating urethral trauma caused by a blast injury due to an improvised explosive device is an extremely rare clinical condition and treatment options are limited due to accompanying massive tissue and muscle loss. Staged urethral reconstruction using a pedicled gracilis muscle flap with a skin or buccal mucosa graft is the preferred treatment option for complex urethral traumas. In case of a devastated urethra due to an intensive explosive device injury, treatment options are limited, especially if the gracilis muscle cannot be used. We report the case of a 30-year-old male patient with a devastated bulbopenile urethra and massive local tissue and adjacent muscle loss including the gracilis muscle. The patient was successfully treated by buccal mucosa graft tube urethroplasty. Urethral stricture recurred but was successfully treated by means of endoscopy. At 24 months' follow-up, the patient was continent and urinated normally.

Bilateral renal metastasis of an inguinal malignant solitary fibrous tumor, 9 years after primary surgical treatment.

OBJECTIVE: To report the first case of a bilateral renal solitary fibrous tumor (SFT) as a metastasis of an inguinal malignant SFT. CLINICAL PRESENTATION AND INTERVENTION: A 60-year-old male patient with a history of a right inguinal 7 × 8 cm soft tissue mass excision 9 years ago was referred to our clinic with abdominal pain. Both physical examination and chest X-ray were normal. Computed tomography revealed bilateral renal tumor. He was successfully treated with left partial and right radical nephrectomy. Histopathological examination showed a metastasis of the previous inguinal SFT. CONCLUSION: This case showed that although malignant SFT is extremely rare in the urogenital tract, this tumor should be included in the differential diagnosis when identified in the kidneys.

Restorative effects of red onion (Allium cepa L.) juice on erectile function after-treatment with 5α-reductase inhibitor in rats.

Benign prostatic hyperplasia (BPH) is one of the most prevalent conditions among aged men. The use of 5α-reductase inhibitors (5-ARIs) to treat BPH was linked to erectile dysfunction (ED). Many medicinal plants and secondary metabolites are used in the management of ED. Onion (Allium cepa L.) is an economically affordable vegetable with vital phytochemicals and biological functions. The study aimed to identify the beneficial effects of onion juice on dutasteride (a 5-ARI)-induced ED. Rats were divided into two groups (n = 5 per group): control and dutasteride-treated rats (0.5 mg/kg/day). Dutasteride was administered in drinking water for 12 weeks. Experiments were performed at the end of the 12th week. In vivo erectile responses were measured before and after intracavernosal injection of onion. Relaxant responses to onion juice were examined in the corpus cavernosum (CC). Acetylcholine (ACh)-, electrical field stimulation (EFS)-, sodium nitroprusside (SNP)-induced relaxation responses in CC tissues were evaluated in the absence and presence of onion juice. Total intracavernosal pressure (ICP) and ICP/ mean arterial pressure were significantly reduced in dutasteride-treated rats (1881.14 ± 249.72 mmHg, P < 0.001;0.26 ± 0.03, P < 0.01) as compared to control rats (4542.60 ± 429.19 mmHg, 0.51 ± 0.05), which was normalized after the intracavernous administration of onion (3288.60 ± 185.45 mmHg, 0.58 ± 0.04). Onion markedly induced relaxant responses in control (72.5 ± 4.7) and dutasteride-treated (66.5 ± 2.7) groups after precontraction with phenylephrine. Relaxation responses to onion were partially inhibited after precontraction with KCl (32.5 ± 3.1, P < 0.001). The relaxant responses to ACh (14.9 ± 4.2, P < 0.01) were diminished in dutasteride-treated CC) compared to control CC (59.8 ± 3.4), which was enhanced after the incubation with onion (36.6 ± 4.8). There were no differences in relaxation response to SNP among all groups. However, relaxation response to SNP was reduced in dutasteride-treated CC at 1 µM (P < 0.05) and 10 µM dosages (P < 0.001), which was partially increased after the incubation with onion at 10 µM dosage (P < 0.01). The presence of onion did not change the reduction in EFS-caused relaxation in the dutasteride-treated group. The current data suggest that red onion juice has a restorative effect on erectile function and endothelium-dependent relaxation response following the treatment of dutasteride.

Our experience on Fournier's gangrene in a tertiary-stage care center and analysis of its relationship with blood count parameters.

BACKGROUND: Fournier's gangrene (FG) is rapidly progressing and life-threatening necrotizing fasciitis of genital and perineal regions. The aim of the study was to share our experience with FG and to analyze the relationship of clinical data with whole blood count parameters, inflammation cells, and systemic inflammation markers. METHODS: The digital medical records of the adult patients followed-up and treated with diagnosis of FG between January 2016 to December 2020 were retrospectively analyzed. Data were as age, gender, total length of hospital stay, predisposing factors, etiological factors, total number of debridement's, surgical procedures, and antibiotherapy were collected. Serum glucose levels, complete blood count parameter levels, serum inflammation indicators and C-reactive protein (CRP) levels measured at the initial day of hospital admission, post-debridement 1st and 7th days were measured. RESULTS: Thirty-six male patients were included, with a mean age of 56.42 (22-86) years. The most common predisposing factor was diabetes mellitus (n=13; 36.1%). The most frequently seen etiological cause was scrotal abscess (n=19; 52.8%). A statistically significant decrease was found in White blood cell count, neutrophil level, neutrophil-to-lymphocyte ratio (NLR) value and CRP level measured before debridement, post-debridement 1st and 7th days (p<0.05). There was a positive correlation between the number of debridement's and age, NLR, platelet-to-lymphocyte ratio, and CRP values at the initial admission time (p<0.05). CONCLUSION: The infections of urogenital region are the essential etiological origin of FG. As a rare urological emergency, significant changes were observed in clinical data and blood count parameters during the course of FG.

Extraperitoneal laparoscopy-assisted percutaneous nephrolithotomy in a patient with osteogenesis imperfecta.

Osteogenesis imperfecta (OI) patients represent a challenge to all physicians, as they do for anesthetists and urologists, when they develop symptomatic stones in the urinary tract. We recently treated an OI patient with renal pelvic stone by extraperitoneal laparoscopy-assisted percutaneous nephrolithotomy (PCNL). To our knowledge, this combined treatment modality has not been reported previously in OI. An 18-year-old paraplegic girl with OI presented to our urology department because of right-sided flank pain. She pointed out that she had right kidney stone for the previous 2 years, and because of risks of general anesthesia and surgical procedures, surveillance was recommended. Intravenous pyelography was performed and an 11.9-mm stone at the pelvis of the right kidney and grade 1-2 hydronephrosis at the same side with normal kidney functions and severe left-sided scoliosis were detected. After explanation of risks of the treatment modality and general anesthesia to the patient, extraperitoneal laparoscopy-assisted PCNL was performed. No complications occurred due to general anesthesia or surgical procedure. The operation time was 95 min and no blood transfusion was required. The nephrostomy tube and retroperitoneal drain were removed 2 and 3 days after the procedure, respectively. The patient was doing well at a follow-up of 6 months. Extraperitoneal laparoscopy-assisted PCNL approach may decrease the risk of surgery as an alternative treatment modality for OI patients. Such cases should be operated on at centers with significant experience in the field of endourology, where all the equipment and specialized personnel are readily available.

Effects of vardenafil on testicular torsion/detorsion damage: an experimental study in pigs.

PURPOSE: To investigate the effects of vardenafil HCl on testicular germ cell apoptosis and the expressions of iNOS and eNOS within the bilateral testes after unilateral torsion/detorsion (T/D) in a pig model. METHODS: 12 male pigs weighing 50-55 kg were divided randomly into three groups (n = 4). Sham operation and T/D was performed in groups 1 and 2, respectively. Group 3 underwent T/D and received vardenafil (0.4 mg/kg) orally 45 min before detorsion. The testes were left in torsion for 2 h. In all groups, both testes were removed 8 h after the operation for histopathological analysis. RESULTS: Except for group 1, the histopathologic parameters of the ipsilateral testes were higher than in the contralateral testes, and this difference was statistically significant (p < 0.05). Testicular ischemia/reperfusion (I/R) (group 2) resulted in marked increases in germ cell apoptosis, iNOS and eNOS in the ischemic testes compared to the sham-operated group. The pigs treated with vardenafil (group 3) also showed significantly increased apoptotic cells, iNOS and eNOS levels compared to the sham-operated group. CONCLUSIONS: The results suggest that vardenafil HCl worsened histopathological changes related to oxidative stress in testicular injury and had no protective effect on testicular I/R injury in pigs.

Post-chemotherapy modified template retroperitoneal lymph node dissection in patients with nonseminomatous germ cell tumours.

INTRODUCTION/BACKGROUND: Although a full bilateral template RPLND is thought to be the standard of care for the management of postchemotherapy retroperitoneal residual masses for nonseminomatous germ cell tumors (NSGCT), in the past decade modified templates have become increasingly popular. In this study, we aimed to present our oncological and perioperative outcomes of consecutive seventeen NSGCT patients who underwent a modified template unilateral PC-RPLND for retroperitoneal residual disease. MATERIALS AND METHODS: We retrospectively evaluated the medical records of 17 consecutive NSGCT patients who underwent modified template unilateral PC-RPLND in our university hospital between 2017 and 2020. All patients had normal serum tumour markers with residual disease in the retroperitoneum. Surgical characteristics including the size of the retroperitoneal residual mass, residual tumor pathology, removed lymph nodes, positive percentage of removed lymph nodes, accompanying operations, complications, mean operation time and hospital stay, and long-term results including survival and antegrade ejaculation were evaluated. RESULTS: Eleven patients underwent left and six right-sided surgery. Median residual lymph node diameter was 41mm. Median hospitalisation time was 3.5 days. Median follow-up time was 10.5 months. Necrosis/fibrosis was seen in 6 patients, and teratoma in 11 patients. No viable tumour was seen. No patients died in the follow-up period. None of the patients relapsed during follow-up. Ten/seventeen patients had antegrade ejaculation. CONCLUSIONS: Modified template unilateral PC-RPLND leads to very good oncological outcomes with decreased perioperative morbidity as well as better antegrade ejaculation rates. Low volume retroperitoneal disease seems to fit this procedure best.

Examination of clinical data and semen analysis results of patients undergoing orchiectomy for testicular tumor.

OBJECTIVE: Testicular tumor constitutes 1% of male neoplasms. Infertility can be determined in patients with testicular tumors before orchiectomy due to the deterioration of spermatogenesis. The aim of this study was to show the clinical, radiological, and pathological characteristics and spermiogram results of patients with testicular tumor and their relationship with each other. METHODS: The data of patients who underwent orchiectomy due to testicular tumor between 2016 and 2019 were reviewed retrospectively. These data included sociodemographic data of the patients, pretreatment spermiogram characteristics, level of serum tumor markers, characteristics of the ultrasonography, type of orchiectomy, and histopathological examination. RESULTS: This study included 53 male patients, with a mean age of 33.51±12.86 years. The mean levels of all tumor markers were above the reference levels. The mean tumor size was 34.68±23.32 mm. Multiple localizations and microlithiasis were detected in 11.3 and 13.2% of the tumors, respectively. The most common masses were hypoechoic (n=37; 69.8%) and hypervascular (n=47; 81%). Spermiogram and cryopreservation were performed in 29 (54.7%) of 53 patients preoperatively. The mean sperm concentration before orchiectomy was 24.21×106 /mL and group A sperm motility 0.79%, group B sperm motility 39.10%, group C sperm motility 9.83%, and group D sperm motility 22.69% in testicular tumors. CONCLUSION: Spermatogenesis adversely affected before the treatment due to local and systemic effects of testicular cancer. Fertility expectations can be increased in the subsequent years by semen analysis and referral to cryopreservation.

Determination of Face and Content Validity of Cadaveric Model for Holmium Anatomic Endoscopic Enucleation of the Prostate Training: An ESUT AEEP Group Study.

BACKGROUND: Bench and virtual reality nonbiological simulator models for anatomic endoscopic enucleation of the prostate (AEEP) surgery have been reported in the literature. These models are acceptable but have limited practical applications. OBJECTIVE: To validate a fresh-frozen human cadaver model for holmium AEEP training and assess its content validity. DESIGN SETTING AND PARTICIPANTS: Holmium AEEP operations on fresh-frozen cadavers performed by an experienced surgeon were recorded, and a video, including the main steps of the operation, was produced. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The video and an accompanying questionnaire were subsequently distributed electronically to ESUT AEEP study group experts and associates (N = 32) for assessment of the AEEP training model. A ten-point Likert global rating scale was used to measure the content validity. RESULTS AND LIMITATIONS: A total of 26 answers were returned (81%). The experts agreed on the model's suitability for AEEP training (mean Likert score: 8). According to the responses, "identifying anatomic structures and landmarks" was the most valuable aspect of the model in terms of AEEP training (median Likert score: 9). Conversely, the experts found the model's ability, in terms of demonstrating laser and tissue reactions, to be weak (median Likert score: 6). CONCLUSIONS: Based on the content validity assessment, the fresh-frozen cadaver-training model for laser AEEP seems to be a promising model for demonstrating and learning the correct prostate enucleation technique. PATIENT SUMMARY: An increasing number of researchers have proposed that anatomic endoscopic enucleation of the prostate (AEEP) should replace transurethral resection of the prostate surgery and become the gold standard for treatment of bladder outlet obstruction due to benign prostatic hyperplasia. AEEP requires anatomic familiarity for enucleation, technical knowledge, and a solid training program before starting with the first cases. This is the first cadaver study to assess the content validity of a fresh-frozen human cadaver model for AEEP training.

Assessment of In Vitro Antigenotoxic Effect of Nigella Sativa Oil.

OBJECTIVES: Cyclophosphamide (CP) is an alkylating agent widely used as an antineoplastic and immunosuppressive agent. The genotoxicity of CP has been studied in a variety of in vivo and in vitro systems and is routinely used as a positive control in genotoxicity tests. Traditional medicine Nigella sativa L., (N. sativa), Ranunculaceae family, especially in the Eastern Mediterranean countries, especially in many countries, and is widely used in many countries as a spice and folk medicine since the time of Dioscorides used as a plant. In this study, it was aimed to show the protective effects of N. sativa oil at different concentrations against the genotoxic effects of CP by micronucleus test. MATERIALS AND METHODS: For this purpose, healthy cells were treated in vitro with N. sativa oil at concentrations of 1, 5, 10 µg/mL and CP as positive control for 68 hours. The micronuclei were then counted. RESULTS: No significant increase in micronucleus frequency was observed when the application of N. sativa oil at concentrations of 1, 5, 10 µg/mL compared with the negative control. There was a decrease in the number of micronucleus in all three concentrations (1, 5, 10 µg/mL) compared to the CP group in the groups treated with N. sativa oil and CP. CONCLUSION: It has been shown that N. sativa oil may have protective effects against genotoxicity agents in vitro. But more work is needed to understand the mechanism of the genotoxicity effects of N. sativa oil.

Anesthesia management for robotic assisted radical prostatectomy. Single center experince.

AIM: The aim of this study was to present our experiences for anesthesia management in patients undergoing robot-assisted radical prostatectomy (RARP) in light of current literature data. MATERIAL AND METHODS: This clinical retrospective study included 103 patients who underwent robot-assisted radical prostatectomy. All patient data were obtained from the patient files and anesthesia follow-up forms. Demographic datas, intraoperative fluids, blood products requirement and blood gas parameters were recorded. RESULTS: A total 15 of 103 patients data were lack, the remaining 88 patients were evaluated. Combination of crystalloid and colloid was used for intravenous fluid management. About 11% of patients required transfusion during surgery. The mean pH and pO2 values of the patients were observed to decrease whereas pCO2 and lactate values increased. DISCUSSION: Radical Prostatectomy can be performed either using open technique as a traditional approach or laparoscopic or robot-assisted technique as a minimally invasive approach. Today, minimally invasive approaches have replaced traditional open prostatectomy. Anaesthesia management of these minimally invasive techniques is very different and challenging from open technique in many aspects. CONCLUSION: Although minimally invasive techniques have good surgical outcomes such as less blood loss, smaller surgical incision, and shorter hospitalization, these techniques bring new problems that anesthesiologists have to deal with. Increased RARP operations has led to the anesthesiologists more likely to encounter perioperative problems. KEY WORDS: Anesthesia, Minimally invasive techniques, Radical prostatectomy.

The clinical features and treatment options of intratesticular epidermoid cysts. / Las características clínicas y opciones de tratamiento de los quistes epidermoides intratesticulares.

OBJECTIVES: In this study, we aimed to define the clinico-radiological data and treatment options for intratesticular epidermoid cysts (IEC). MATERIALS AND METHODS: We retrospectively reviewed the medical records of the patients that under went surgery for testicular mass between 1995 and 2017. Data of the patients whose histopathological evaluation revealed IEC were recorded.  RESULTS: A total of 20 patients with IEC were identified.While three of 20 patients were excluded due to incomplete data, the remaining 17 patients with pathologically proven IEC were reviewed and analyzed in the study. The mean patient age was 22.2 years (range, 17-29 years). All patients were presented with painless testicular swelling and/or mass. Serum tumor markers of all patients were within the ranges. Four patients treated with radical orchiectomy (23.5%), while 13 patients under went partial orchiectomy (76.5%). The mean size ofthe IEC was 17.7x15.1 mm (range, 26x10 mm). IEC swere mostly located in the middle pole of the testes (10of 17 patients, 58.8%). CONCLUSIONS: This study is designed in retrospective nature, but the patient population is one the largest reported in the literature. According to our study, we can easily state that partial orchiectomy can be performed safely after FSA in patients that have IECs.

OBJETIVOS: En este estudio, nuestro objetivofue definir los datos clínico-radiológicos y las opciones de tratamiento de los quistes epidermoides intratesticulares (CEI). MATERIALES Y MÉTODOS: Revisamos retrospectivamente los registros médicos de los pacientes que se sometieron a cirugía para la masa testicular entre 1995 y 2017. Entre ellos se registraron los datos de los pacientes cuya evaluación histopatológica reveló IEC. RESULTADOS: Se identificaron un total de 20 pacientes con IEC. Mientras que tres de los 20 pacientes fueron excluidos debido a los datos incompletos, los 17pacientes restantes con IEC patológicamente probada se revisaron y analizaron en el estudio. La edad media de los pacientes fue de 22,2 años (rango, 17-29años). A todos los pacientes se les presentó hinchazón y/o masa testicular indolora. Los marcadores tumorales séricos de todos los pacientes estaban dentro de los rangos. Cuatro pacientes tratados con orquiectomía radical (23,5%), mientras que 13 pacientes se sometieron a orquiectomía parcial (76,5%). El tamaño medio de la IEC fue de 17,7x15,1 mm (rango, 26x10 mm). Los IEC se encontraban principalmente en el polo medio de los testículos (10 de 17 pacientes, 58,8%). CONCLUSIONES: Este estudio está diseñado de forma retrospectiva, pero la población de pacientes es una de las más numerosas que se han publicado en la literatura. Según nuestro estudio, podemos afirmar fácilmente que la orquiectomía parcial se puede realizar de manera segura después de la FSA en pacientes que tienen CEI.
