Testis-Sparing Surgery in Small Testicular Masses Not Suspected to Be Malignant

UNLABELLED Fifteen patients with small testicular masses not suspected to be malignant were included in the study, and permanent and frozen section analyses were evaluated. As a result frozen analysis, preoperative externalization of the suspected malignancy with a physical examination, ultrasonographic evaluation, and serum tumor marker analysis were concluded as key points for accurate decision making between TSS and radical orchiectomy. BACKGROUND We aimed to determine the safety, efficacy, and the concordance of permanent and frozen section analysis (FSA) of testis-sparing surgery (TSS) in patients who had small testicular masses that were not suspected to be malignant. PATIENTS AND METHODS Fifteen patients who underwent TSS were included in the study. TSS was performed for the patients who had testicular lesions <25 mm and testicular lesion volume <30% of the whole testis. All patients had normal serum tumor marker levels and ultrasonographic evaluation did not indicate malignancy. Surgery was performed via an inguinal approach with temporary cord occlusion and FSA of the lesions. Benign findings allowed for TSS, and cancer prompted total orchiectomy. RESULTS The mean patient age was 25.33 (range, 20-36) years. The predominant complaint was swelling (9 patients). The mean lesion diameter was 16 mm (range, 5-26 mm). Fourteen of all cases (93%) had benign pathology and underwent TSS. Only 1 patient, whose FSA revealed malignant formation, underwent radical orchiectomy. Final pathology of this patient was seminoma. Complete histopathologic concordance was observed between the results of frozen and permanent sections. TSS was performed with no intra- or postoperative complications. After a mean follow-up of 23 months (range, 6-44 months) all patients, except 3 who were lost to follow-up, were free of disease. CONCLUSION The main key points for accurate decision-making between TSS and radical orchiectomy are intraoperative FSA and preoperative externalization of possible suspected malignancy with physical examination, ultrasonographic evaluation, and serum tumor marker analysis.

Inhibition of inducible nitric oxide synthase prevents shock wave therapy induced renal injury.

Abstract Objectives: Shock wave lithotripsy treatment (SWT) is not completely free from side effects; one of the accused mechanisms for renal injury during SWT is oxygen- and nitrogen-derived free radical productions. Therefore, we aimed to evaluate the effect of inhibition of nitric oxide (NO) production by N-[3(aminomethyl) benzyl) acetamidine] (1400W), highly selective inducible nitric oxide synthase (iNOS) inhibitor, at SWT-induced kidney damage. Materials and methods: Twenty-four rats those underwent right nephrectomy procedure were divided equally into three groups as control, SWT, and SWT + 1400W. 1400W was administered at a dose of 10 mg/kg at 2 h prior to SWT procedure and at the beginning of SWT procedure via intraperitoneal route and continued daily for consecutive 3 days. At the end of the fourth day, animals were killed via decapitation and trunk blood and the left kidneys were taken for biochemical and histopathologic evaluation. Results: SWT caused renal tubular damage and increased lipid peroxidation and antioxidant enzyme activities and SWT also significantly increased nitro-oxidative products. Inhibition of iNOS via administration of 1400W ameliorated renal injury and decreased tissue lipid peroxidation (malondialdehyde), superoxide dismutase, glutathione peroxidase and nitrite/nitrate levels (NOx). In addition, it was seen that histolopathological changes were attenuated in the SWT + 1400W group when compared to SWT group. Conclusion: SWT-induced renal injury might be due to excessive production of oxygen free radicals and NO production. Inhibition of iNOS attenuates renal injury following SWT treatment. It can be concluded that iNOS inhibitors or peroxynitrite scavengers might be used to protect the kidneys against SWT-induced morphological and functional injuries.

Persistent Mullerian duct syndrome with transverse testicular ectopia and seminoma.

Persistent Mullerian duct syndrome (PMDS) is a rare form of the 46 XY disorders of sexual differentiation, characterized by the presence of a uterus and fallopian tubes due to the failure of Mullerian duct regression in genotypically normal males. More than 150 cases have been recorded, most of them in adults. In most cases, the PMDS is discovered during surgery for inguinal hernia or cryptorchidism, or by the presence of transverse testicular ectopia (TTE). The presence of PMDS with TTE is even more uncommon. In TTE, both testes descend through the same inguinal canal into the same scrotal sac. Patients with TTE present with symptoms of unilateral cryptorchidism and a contralateral inguinal hernia. For patients with inguinal hernia and cryptorchidism associated with TTE, PMDS should be kept in mind, and radiologic evaluation such as ultrasonography or magnetic resonance imaging of the genitourinary system and karyotyping are recommended. Whereas radiologic evaluation could be helpful in the diagnosis of TTE, it cannot diagnose the malignancy itself. The case explained in this report will offer urologists additional useful treatment strategies for patients with inguinal hernia and cryptorchidism.

Bilateral polyorchidism with ipsilateral two undescended testes: a rare congenital anomaly

Polyorchidism is defined as the presence of more than two testes. This rare congenital anomaly has been reported with only 140 pathologically proven cases in the published literature to date. While triorchidism is the most common variation and generally affects the left side, bilateral polyorchidism is even rare and only seven cases of patients with four testes have been reported in the literature. There is no consensus in the literature regarding the management of supernumerary testis due to its rareness. We report such a rare case of a 20‐year‐old male patient, who was presented with left‐sided scrotal mass and right inguinal swelling and, diagnosed as polyorchidism including four distinct testes, with two of them in left hemiscrotum and the other two testes in the right inguinal canal. The patient underwent orchiopexy for the normal looking right‐sided testis, and orchiectomy for the right‐sided supernumerary testis being dysmorphic and potential malignancy risk. Histopathological examination confirmed the excised tissue to be severely atrophic testicle. The patient is still following with regular self‐examination and scrotal ultrasonography. Polyorchidism should be keep in mind especially for the differential diagnosis of extratesticular and paratesticular masses. Physical examination may not be sufficient, and radiologic examination can provide accurate diagnosis. Conservative, extirpative or reconstructive approaches could be performed based on individual basis by reproductive potential and location of supernumerary testis, coexistence of other disorders and suspicion of malignancy.

Association of Torsion With Testicular Cancer: A Retrospective Study

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.

Medical ozone therapy reduces shock wave therapy-induced renal injury

Abstract 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.

Affective Temperament Profiles of Overactive Bladder Patients

We have read the article “Affective Temperament Profiles of Overactive Bladder Patients” presented by Saribacak et al. with great interest (1). This study assesses the potential relationship between the overactive bladder (OB) disease profile of individuals with temperament. The authors reported that there might be a relationship between OB syndrome, which presents as serotonergic dysfunction, and anxious temperament.

RE: ultrasonic Measurement of Testicular Tumors and the Correlation with pathologic Specimen Sizes

We read with great interest the article “The value of testicular ultrasound in the prediction of the type and size of testicular tumors” by Shtricker et al. (1). They aimed to assess the correlation between ultrasound (US) findings and testicular tumor type and size. The authors concluded that the testis US findings underestimated the size in 25% of the malignant testicular lesions and 16% of the cases were proven to be benign. Thus they recommended putting into practice frozen sections for borderline cases. This study gives substantial information on this clinically relevant condition. The awareness of this diagnostic finding and its clinical results may increase the accuracy of preoperative management of the patients with testicular lesions. Thanks to the authors for this contribution. Several medical subspecialties manage their treatments with respect to anatomic measurements. The reproducibility and accuracy of the measurements are especially crucial in radiology as important clinical decisions are often based on the assumption that radiologic measurements are accurate and any measurement differences on follow-up imagings represent a real change in size. Favorably, measurements of the tumors on images should be accurate, reproducible, and practiced in a standardized method with low rates of intra-and interobserver variability. Even so, there a lot of factors, which may affect the consistency of the measurement, including patientdependent factors, technical factors and radiologist-dependent factors (2,3). World Health Organization criteria (WHO) (4) and the Response Evaluation Criteria in Solid Tumors (RECIST) (5) are two widely accepted guidelines of measurement methods to obtain standardized results (6). WHO criteria recommend the measurement method on the basis of an approximation of cross-sectional area (bidimensional measurement), whereas RECIST suggests to measure only the tumor’s greatest diameter (unidimensional measurement) on a transverse plane (7). Shtricker et al. have designed this study as a multicenter study (1). This design may increase the variabilities in the tumor measurement. However, the authors did not mention any measurement method for standardization in the study. A lot of published studies based on the variability and reproducibility of tumor measurements define their measurement methods and they generally use WHO or RECIST criteria. Therefore a measurement variability might occur due to lack of measurement standardization. Vol. 42 (1): 172-173, January February, 2016

Standard surgical approach of testissparing surgery for testicular tumour with benign or malignant tendency

tomy in select cases. These conditions are small testicular tumours, synchronous bilateral tumours, metachronous contralateral tumours, or tumour in solitary testis in patients for whom tumour volume is <30% of the testis volume and in whom preoperative testosterone levels are normal. 2
