RESUMO

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.

RESUMO

A 49-year-old male patient was diagnosed with ADPKD while the evaluation of urinary tract infection in 2010. He was suffering from nutritional problems due to gastro-intestinal disturbances and vomiting secondary to the pressure of the kidneys. He was also a candidate for kidney transplantation, but there was no adequate and enough space in the abdomen for the transplant kidney. Therefore, we performed open unilateral nephrectomy to the bigger kidney. As we now there is not too many cases regarding giant polycystic kidney nephrectomy, we presented our case to make additional contribution to the current literature


Se diagnosticó poliquistosis renal autosómica dominante a un paciente masculino de 49 años durante la evaluación de un cuadro de infección urinaria en 2010. El paciente padecía problemas nutricionales debido a trastornos gastrointestinales y vómitos causados por la presión de los riñones. Asimismo, era candidato a trasplante renal, pero el espacio del abdomen no era adecuado ni suficiente para realizar este procedimiento. Por lo tanto se realizó una nefrectomía unilateral, en el riñón de mayor tamaño. Debido a que no se conocen muchos casos de nefrectomía en pacientes con poliquistosis renal con quistes gigantes, presentamos este para realizar un aporte a la bibliografía existente

RESUMO

INTRODUCTION: There are several techniques employed in the surgical treatment of total or partial penile reconstruction, hypospadias surgery, and urethral stricture. Urethral reconstruction is performed in different ways applying these techniques. OBJECTIVE: We evaluated use of a fibrovascular sheath to create a neo-urethra formed around a silicon tube. MATERIAL AND METHODS: We used nine male New Zealand rabbits for this study. In the first step, we placed a silicone tube under the skin in the lower abdomen of the rabbits and waited for the formation of a fibrovascular sheath to totally surround the tube. In the second step, the silicone tube was removed and the formed fibrovascular sheath was anastomosed with penile urethra over a silicone 8F Foley catheter. Ten days after the second step, the silicone Foley catheter was removed. Twenty days after the second step, we evaluated the newly created neo-urethra with a retrograde urethrogram. Thirty days after the second step, the rabbits were sacrificed and the bladder, urethra, and neo-urethra were removed for histopathological examination. RESULTS: Six of the rabbits completed the study. After the first operation, in the third month, formation of the fibrovascular sheath was observed around the silicon tube. After anastomosis and removal of the silicon Foley catheter, urine was seen to pass through the neo-urethral meatus. Urethrocystography showed that the neo-urethra and penile urethra were aligned and urine flow was regular. Histopathological evaluation showed that the structural integrity of the newly formed urethra was comparable with the structure of the regular urethra (Table) and the calibration did not change over time, although the newly formed urethra was not covered with uroepithelium. CONCLUSIONS: In this study, we achieved promising results with use of a newly formed fibrovascular sheath as a neo-urethra.

RESUMO

OBJECTIVES: The purpose of this study was to determine prognostic factors affecting semen parameters in patients with varicocele during the postadolescent period. METHODS: This study was approved by the Institutional Review Board. Between May 2013 and May 2015, we prospectively obtained demographic and sonographic data from postadolescent patients with varicocele. Potential risk factors affecting semen parameters, including age at diagnosis, height, weight, body mass index, varicocele laterality, varicocele grade, left testicular volume, right testicular volume, total testicular volume, testicular atrophy index, testicular volume differential, right and left maximum vein diameters, peak retrograde flow velocity, reflux flow volume, and reflux grade in both supine and standing positions, were recorded. RESULTS: The left peak retrograde flow velocity, reflux flow volume, and reflux grade in the supine and standing positions, left testicular volume, right testicular volume, total testicular volume, and follicle-stimulating hormone level were found to be associated with abnormal semen parameters (P < .05). By multivariate analysis, the follicle-stimulating hormone level was associated with the sperm concentration and morphologic characteristics, and the left peak retrograde flow velocity in the standing position was associated with deterioration of sperm motility and morphologic characteristics. Additionally, the left reflux grade in the standing position was associated with the sperm concentration, and the left testis volume was associated with motility. CONCLUSIONS: The left peak retrograde flow velocity and reflux grade in the standing position were significantly associated with all semen analysis parameters. This finding supports the use of testicular duplex Doppler sonography as a noninvasive tool for evaluation of testicular function in patients with varicocele and helps clinicians determine patients' fertility status.

RESUMO

OBJECTIVES: Extracorporeal shock wave (ESW) lithotripsy is the preferred treatment modality for uncomplicated kidney stones. More recently free oxygen radical production following ESW application has been considered to be crucial in shock wave-induced renal damage. It has been shown that ozone therapy (OT) has ameliorative and preventive effects against various pathological conditions due to increased nitro-oxidative stress. In current study, we aimed to evaluate the efficacy of OT against ESW-induced renal injury. METHODS: Twenty-four male Sprague-Dawley rats were divided into three groups: sham-operated, ESW, and ESW + OT groups. All groups except sham-operated group were subjected to ESW procedure. ESW + OT group received 1 mg/kg/day of oxygen/ozone mixture intraperitoneally at 2 h before ESW, and OT was continued once a day for consecutive three days. The animals were killed at the 4th day, and kidney tissue and blood samples were harvested for biochemical and histopathologic analysis. RESULTS: Serum ALT and AST levels, serum neopterin, tissue nitrite/nitrate levels, and tissue oxidative stress parameters were increased in the ESW group and almost came close to control values in the treatment group (p < 0.05, ESW vs. ESW + OT). Histopathological injury scores were significantly lower in treatment group than the ESW group (p < 0.05, ESW vs. ESW + OT). Immunohistochemical iNOS staining scores in ESW group were higher than those of sham-operated group (p < 0.05, ESW vs. sham-operated), iNOS staining scores in OT group were significantly lower than the ESW group (p < 0.05, ESW + OT vs. ESW). CONCLUSION: OT ameliorates nitro-oxidative stress and reduces the severity of pathological changes in the experimental ESW-induced renal injury of rat model.

RESUMO

UNLABELLED: Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported with the association of torsion in surgical specimens, and the published data remain scant on the association of torsion with testicular tumors. By retrospective medical record review, we identified 32 patients who had been diagnosed with testicular torsion, 20 of whom had undergone orchiectomy. Of these 20 patients, 2 were diagnosed with a malignancy. Our study, the largest case series to date, has shown an association between testicular torsion and testicular cancer of 6.4%. BACKGROUND: Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported in association with torsion in surgical specimens. However, the published data remain scant on the association between torsion and the presence of testicular tumors. The present retrospective study explored the association between torsion and testicular cancer in patients with testicular torsion undergoing orchiectomy during scrotal exploration. MATERIALS AND METHODS: A medical record review was performed of patients who had had a diagnosis of testicular torsion from January 2003 to February 2015. The clinicopathologic characteristics of the patients were recorded. RESULTS: A total of 32 patients were identified. Their mean age was 21.1 years (range, 7-39 years). All the patients had unilateral testicular torsion, which affected the left side in 17 and the right side in 15. Manual detorsion was successful in 6 patients, and 26 patients underwent emergency surgery with testicular detorsion (6 fixation surgery and 20 orchiectomy). The type of incision was scrotal in 6, inguinal in 10, and unspecified in 4. Pathologic examination of the orchiectomy specimens showed malignancy in 2 cases (seminoma and malign mixed germ cell tumor). CONCLUSION: To the best of our knowledge, the present single-center case series is the largest case series to date of testicular torsion and showed an association between testicular torsion and testicular cancer of 6.4%. However, further larger series of the association between testicular torsion and cancer are needed to explore the relationship between testicular torsion and testicular cancer.

RESUMO

The penis as a component of external genitalia, takes part in fertility, urinary and psychosexual structure of males with its complex character. We report a case of penis agenesis with associated left renal agenesis, left superior segment ureteral agenesis, prostate agenesis, left ureterocele, right vesicoureteral reflux and high urethrorectal communication above the rectal sphincter. The patient refused any surgical intervention because of his religious beliefs.

RESUMO

The objective is to compare immediate and delayed SWL as a treatment for ureter stones between 5 and 20 mm. Patients who applied to the emergency department with single, radio opaque ureteric stone of 5-20 mm size were included in the study. Patients were randomized into immediate and delayed SWL groups. SWL were carried out after pain relief in the delayed group. Maximum of three SWL sessions were applied to the patients with stones of 5 mm or bigger in diameter, leaving at least 3 days interval in-between. Stone-free rate after first session was similar in two groups. When CIRF was also considered as success, the success rate of SWL in the immediate SWL group was higher after first session (p = 0.02). Immediate SWL had a greater success rate in upper ureteric stones (p = 0.019). Overall average time required for elimination of stones was shorter in immediate SWL group than delayed SWL group (p = 0.033). The success rate after first SWL session (including CIRF) was 59 % for patients with chronic pain in the delayed group and 100 % for patients with acute pain in the immediate group. According to the hydronephrosis grade, success rates were 71 and 44.4 % for patients with grade 1 or no hydronephrosis in the immediate SWL group, and for patients with grade 2 or larger hydronephrosis in the delayed SWL group, respectively, after first SWL session. Immediate SWL insures stone-free status in a shorter time in cases with renal colicky pain and ureteral stones, particularly upper ureteral stones.

RESUMO

BACKGROUND: The dorsal nerve block of the penis during circumcision has not been standardized and the effectiveness of the block can be changeable. The aim of this study was to determine which technique is more suitable for blocking sensory innervations of penis. METHODS: This prospective study was done on adults who voluntarily applied to be circumcised. Patients were randomized into three distinctive groups; first, just circular infiltration; second, circular plus dorsal penile infiltration; and third, circular plus ventral upward infiltration. Sensation was tested using pinprick sensory testing before and after infiltration. The total duration of the procedure was recorded. RESULTS: In total, 89 adult uncircumcised men were included into the study. The average age of men was 21.4 (min: 20; max: 25). The average operation time in the third group was significantly shorter. The sensation distribution, especially around the frenulum sensitivity results were in the first minute 100, 81.3, 72.4 %; in the third minute 85.7, 37.5, 20.7 %; and in the fifth minute 57.1, 18.8, and 0 % for the first, second, and third group, respectively. In the fifth minute, there was no sensitivity for any patients in the third group and it was significant. CONCLUSION: Circular plus ventral upward anesthesia is an easy and feasible technique for local anesthesia in circumcision.

RESUMO

BACKGROUND AND PURPOSE: There are no definite data indicating which modality to use to assess the efficacy of shockwave lithotripsy (SWL). Usually, plain abdominal radiography (PAR) is recommended in percutaneous nephrolithotomy (PCNL) afterward and in the follow-up of asymptomatic stones, whereas noncontrast CT (NCCT) is recommended in cases of residual fragments. We compared the efficacies of PAR and NCCT in terms of assessing the outcome of SWL treatment for radiopaque ureteral stones. PATIENTS AND METHODS: Those patients with renal colic and a radiopaque ureteral stone of 5 to 20 mm that was detected on PAR were included in the study; body mass index (BMI) values were calculated and recorded. Patients whose PAR revealed opacities suspicious for ureteral stones were evaluated with NCCT at 3-mm slices. Stone status was assessed with PAR and NCCT on post-SWL day 3. Detection of no stone, a residual fragment of ≤ 4 mm, and a residual fragment of >4 mm was defined as success, clinically insignificant residual fragments, and failure, respectively. RESULTS: On post-SWL day 3, both PAR and NCCT revealed stones in 31 patients, and no stones were seen in either modality in 29 patients. NCCT revealed stones whereas PAR had negative results for stones in two patients. These patients had upper ureteral stones of 7.5 mm (6-9 mm) before SWL. Mean stone size on NCCT after SWL was 2.5 mm (1-4 mm). Mean BMI of these two patients was 27.72, and mean BMI of the patients with upper ureteral stones that were revealed by both PAR and NCCT was 27.68; these two values were statistically similar. CONCLUSION: PAR is capable of detecting clinically significant residual fragments, and patients can be followed up with PAR alone after SWL treatment for radiopaque ureteral stones. This approach both decreases the cost and prevents excessive radiation exposure.
