Effects of bioflavonoids in the management of subclinical varicocele.

BACKGROUND: Subclinical varicocele is a relative rare condition. The aim of this study is to identify the role of bioflavonoids in the management of subclinical varicocele. MATERIALS AND METHODS: We analyzed the medical charts of patients treated for subclinical varicocele with bioflavonoids between 1999 and 2004; inclusion criteria were created before treatment. Short and long-term results after treatment were studied and compared with untreated patients. RESULTS: One hundred and sixty-eight patients with left subclinical varicocele were included in the study. Long-term results showed a possible correlation between use of bioflavonoids and lesser rate of clinical progression to palpable varicocele (11 vs. 31%), higher rate of stable vein reflux (47 vs. 38%) and higher resolution rate (41 vs. 31%) (p > 0.05). Bioflavonoids did not show any protective factor against testicular growth arrest. CONCLUSIONS: Subclinical varicocele should be considered as the starting point of varicocele, and although the use of bioflavonoids in patients with subclinical varicocele could reduce the development of palpable varicocele, it cannot prevent the onset of testicular growth arrest.

A prospective study in children: Pre- and post-surgery use of vitamin E in surgical incisions.

BACKGROUND: One of the main problems of elective surgery is the cosmetic result. OBJECTIVE: This prospective controlled study aims to determine the effects of topical vitamin E on cosmetic results in children. METHODS: A single-blind study was carried out. Topical vitamin E was used on the intended incision site for at least 15 days, thrice daily, before surgery and for at least 30 days, twice daily, after surgery (group A). The control group received topical petrolatum-based ointment (group B). RESULTS: No patients in group A developed keloids. A total of 96% of patients (or parents) considered the cosmetic results very good. No patients had wound infection. In the control group, only 78% of patients (or parents) considered the cosmetic results very good and 13 (6.5%) patients developed keloids after 6 months. There were no cases of wound infection. CONCLUSION: Topical vitamin E before and after surgery improved surgical wound healing and improved cosmetic results.

Percutaneous aspiration for hydroceles after varicocelectomy.

OBJECTIVES: To assess the role and efficacy of aspiration alone in the treatment of hydroceles occurring after varicocelectomy. Hydroceles represent one of the most common complications related to varicocelectomy at any age. METHODS: From September 1990 to 2008 at our department, a total of 453 varicocelectomies were performed. Inclusion and exclusion criteria were created. The patients with postoperative hydrocele formation were followed up every 3 months. Aspiration was suggested and then performed after 2 consecutive follow-up visits showing an enlarged hydrocele. In compliance with the protocol implemented at our institution, the clinicians performed >or=3 aspirations before suggesting surgical treatment. RESULTS: A total of 256 patients were considered for the present study. All patients underwent laparoscopic varicocelectomy, and 31 (11%) developed postoperative hydrocele. Of the 31 patients, 9 (29%) underwent surgical hydrocelectomy after 3 aspirations, 7 (22.5%) had spontaneous resolution of the hydrocele, and 15 (48.5%) were treated with aspiration only. The success rate of aspiration seemed to be related only to the aspirated fluid volume, with <50 mL/aspiration guaranteeing spontaneous resolution in 60% of patients (P <.05). CONCLUSIONS: The results of our study have shown that the management of postoperative hydrocele formation should be conservative for almost 18-24 months, with a minimum of 3 aspirations, if necessary. If confirmed by additional studies, the volume of fluid aspirated from hydroceles could be used as an early indicator of the need for surgery.

Unusual presentation of antenatal ovarian torsion: free-floating abdominal cysts. Our experience and surgical management.

BACKGROUND: Abdominal cystic formations in newborns are relatively common and often diagnostic suspicion arises before birth as a result of ultrasound scans carried out during pregnancy. Prenatal ovarian torsion is a rare condition very difficult to manage in the first days of life. We report and discuss the management of prenatal ovarian torsion with a free-floating abdominal cyst detected on prenatal ultrasound. MATERIALS AND METHODS: We recorded the cases of antenatal abdominal cysts detected on ultrasound at the Department of Antenatal Diagnosis between January 2003 and January 2007. Only patients with a free-floating cyst were included in the study. Clinical and surgical findings were then recorded. RESULTS: Two out of 57 patients underwent surgery for a free-floating abdominal cyst during the second day of life. Postnatal ultrasound, Doppler ultrasound, and laparoscopic exploration were useful to identify an unusual presentation of antenatal ovarian torsion with a complete atresia of the Fallopian tube. CONCLUSIONS: The cases reported in this study suggest that a good clinical approach to all cases of abdominal cysts detected on prenatal ultrasound scans require postnatal Doppler and abdominal ultrasound with a laparoscopic exploration. Free-floating abdominal cysts are rare but, at the same time, strictly correlated with autoamputation of the ovary/Fallopian tube complex.

Testicular catch-up growth after varicocelectomy: does surgical technique make a difference?

OBJECTIVES: Catch-up growth of the affected testis in adolescents after varicocele repair has been well documented. Many investigators have found evidence that testicular hypotrophy related to varicocele can be reversed by early intervention. The aim of this study was to analyze the testicular catch-up growth rate in pediatric patients, correlating it with patient age at surgery, varicocele size, procedures used, and semen quality. METHODS: Between March 1990 and September 2006, a total of 465 varicocelectomies were performed at our department. We evaluated the mean testicular volume before and after varicocelectomy in patients aged 9-14 years. Two procedures were used: laparoscopic artery-preserving varicocelectomy (group 1) and open inguinal microscopic artery-preserving varicocelectomy with a venous-venous bypass (group 2). The testicular volume was measured before and after surgery using ultrasonography, and the mean testicular catch-up growth was recorded. RESULTS: Although the overall catch-up growth rate for both groups was 80%, after 18 months, only 45% of patients in group 1 and 34% of patients in group 2 had equal bilateral testicular volume. None of these procedures showed a statistically significant correlation with age at surgery, varicocele size, or catch-up rate. The semen analysis results did not show statistically significant differences between the 2 groups. CONCLUSIONS: Although 80% of patients demonstrated testicular catch-up, with a different distribution depending on the procedure type used but without statistically significant differences, only 32% of patients had complete and real testicular volume catch-up.

Painful varicocele in pediatric age: is there a correlation between pain, testicular damage and hormonal values to justify surgery?

PURPOSE: Pain is one of the indications to treat varicocele at any age. The purpose of this study is to find a possible correlation between pain and objective testicular damage through the analysis of hormonal values. METHODS: Between 1990 and 2001, varicocelectomy was performed on 44 adolescents with painful varicocele using two different techniques. Thirty-eight patients were eligible for the study. Pre- and post-operative hormonal values were analyzed retrospectively to find a possible correlation between pain and testicular damage or discomfort. The patients had to fill out a simple questionnaire about their type of pain following a two-grade rating scale. After treatment, relief of pain or persistence of symptoms were recorded. RESULTS: Six months after surgery 26 patients showed complete relief of pain. There was not a statistically significant correlation between grade of varicocele, type of surgery and relief of symptoms. Clinically there was not a statistically significant correlation between pain and hormonal values. CONCLUSIONS: Management of painful varicocele in pediatric patients should be studied through randomized trials comparing conservative and surgical treatments. While waiting for objective data supporting surgery, clinical evidence justifies varicocelectomy which, on the other hand, is not supported by objective clinical data (i.e., hormonal values).

Recurrent abdominal pain due to buckshots in the appendix.

UNLABELLED: Ingestion of foreign bodies is a common paediatric problem, with more than 100,000 cases occurring each year. The majority of these objects are radiopaque. This paper reports a case of elective appendectomy in a patient with unknown ingestion of buckshots affected by recurrent abdominal pain. Plain abdominal films and ultrasound scans showed that the foreign bodies were located in the right lower abdominal quadrant, more specifically in the appendix. CONCLUSION: Foreign bodies in the appendiceal lumen may cause inflammation, perforation and peritonitis. Surgery seems to be the only effective therapeutic approach to foreign bodies in the appendix.

Relationship between varicocele grade, vein reflux and testicular growth arrest.

The development of testicular hypotrophy (or testicular growth arrest) in pediatric patients with varicocele is the first indication for surgery. The aim of this study is to identify the correlation between grade of varicocele, grade of vein reflux and testicular growth arrest. Between 2000 and 2001, we recruited 226 patients affected by varicocele without testicular hypotrophy and with grades 2-3 spermatic vein reflux observed during Doppler velocimetry. Medical examinations carried out every 6 months allowed the assessment of varicocele grade, testicular volume, and grade of vein reflux. Other parameters considered in the study were: mean time of grade deterioration, mean time to onset of testicular growth arrest and the relationship between varicocele grade and testicular growth arrest. Deterioration of the condition was experienced in 92 patients (40%) in which 60 patients showed higher varicocele grades without testicular growth arrest, while 32 patients developed testicular growth arrest. There was a statistically significant relationship between testicular growth arrest and varicocele grades (grade 2 and 3) and between grade of reflux and testicular growth arrest. Although it is not possible to determine which patients will develop testicular growth arrest, the assessment of vein reflux allows the identification of those subjects who may potentially develop such a condition.

Longitudinal study of semen quality in adolescents with varicocele: to treat or not?

OBJECTIVES: To assess the role of varicocelectomy in pediatric patients through a careful semen analysis. METHODS: A total of 214 patients with grade 2 and 3 left idiopathic varicocele were enrolled. Of these 214 patients, 106 (group 1) were treated surgically for testicular hypotrophy, 54 (group 2) were treated surgically with a normal testis, and 54 with a normal testis (group 3) were observed with follow-up visits every 6 months. The spermiogram results for each group were divided into two subgroups: normal, if they met the evaluation criteria and abnormal in the remaining cases. RESULTS: The spermiogram analysis for groups 1 and 2 showed no statistically significant difference in terms of normal and abnormal spermiogram findings (P >0.01). Even though the patients included in group 3 had reported no testicular hypotrophy or pain, the qualitative semen analysis showed the same trend observed in patients affected by varicocele, but the difference was not statistically significant in the variables considered for the other groups (P >0.01). Preservation of the testicular artery in patients with hypotrophy was associated with better results in terms of semen quality. CONCLUSIONS: Testicular hypotrophy remains the most objective indication for surgical treatment of varicocele, and preservation of the testicular artery gives better results in terms of semen quality only in patients affected by testicular hypotrophy.

Effect of varicocelectomy on the plasma oxidative stress parameters.

AIM OF STUDY: This study evaluates the long-term effect of varicocelectomy as measured by plasma oxidative stress parameters. METHODS: Eleven children aged 10 to 16 years presented with left-sided varicocele and ipsilateral testicular hypoplasia. Peripheral blood samples for C-reactive protein, basal thiobarbituric acid reactive substances (TBARS), and plasma peroxidation susceptibility (lag time and slope) were obtained preoperatively and at 1 year after the varicocelectomy. All patients underwent inguinal microvascular varicocelectomy with testicular-inferior epigastric (spermatic-epigastric) venous shunt, and a blood sample from the pampinous plexus was taken. Student's t test for unpaired and paired data was used with a level of significance set at P < .05. RESULTS: When compared with controls, the cohort preoperative basal TBARS (mean, 2.07 nmol/mL; SD, 0.56 nmol/mL) were higher (P = .009), and plasma peroxidation susceptibility lag time (mean, 132.92 minutes; SD, 32.8 minutes) was lower (P = .0002). Blood samples from the pampiniform plexus showed similar results. Peroxidative plasma levels were significantly reduced on peripheral venous specimens taken 1 year after varicocelectomy with mean (SD) TBARS of 1.53 (0.41) nmol/mL (P = .0003) and mean (SD) lag time of 183.7 (17.46) minutes (P = .0025). The slope did not show significant changes compared with controls, or before and after surgery. CONCLUSION: Peroxidative plasma levels were significantly reduced 1 year after surgery, indicating that surgical varicocelectomy with construction of venous shunt reduces oxidative stress.

Phimosis: stretching methods with or without application of topical steroids?

Phimosis has been defined as unretractable foreskin without adherences or a circular band of tight prepuce preventing full retraction. We suggested a new treatment protocol combining betamethasone with stretching exercises to reduce the number of patients requiring surgery for phimosis. Between January 2003 and September 2004, 247 boys aged 4 to 14 years (mean 7.6) were included in this consecutive, prospective, open study. Patients were treated with 0.05% betamethasone cream applied to the distal aspect of the prepuce twice daily for the first 15 days, then once daily for 15 more days. Preputial gymnastics started 1 week after topical application of betamethasone. Ninety-six percent of patients receiving 1 or more cycles of betamethasone showed complete resolution of phimosis. There was a significant difference (P < .001) in response rate between the study and control groups. Only 10 boys in the study group had no response to steroid and stretching. Treatment with topical steroids, combined with stretching exercises, is a suitable alternative to surgical correction (preputial plasty/circumcision).

Varicocele and retrograde adrenal metabolites flow. An experimental study on rats.

BACKGROUND: Idiopathic varicocele is one of the causes of potentially correctable male subfertility. The mechanisms causing spermatogenesis impairment have yet to be clarified. The aim of this study is to analyze the effects of renal and adrenal metabolite reflux on testicular exocrine function in a rat experimental model. MATERIALS AND METHODS: In the study, 45 male Lewis Stock adult rats, each weighing 300 g, were used. The rats were subdivided into three groups of 15 rats. In group A (control group) testicular volume and basal follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were measured at the beginning of the study and after 9 months. In group B, varicocele was induced by means of rings introduced in the left renal vein in order to cause a renospermatic reflux. In group C, similarly to group B, varicocele was induced after removal of left adrenal gland. The effects of varicocele on testicular function were then analyzed 3, 6 and 9 months after surgery. After 9 months, all rats underwent testicular biopsy. RESULTS: Both groups B and C showed a reduction in testicular volume, an increase in FSH and a decrease in testosterone levels. These levels were higher in group B. Testicular histological assessment showed important structural abnormalities in group B rats. CONCLUSIONS: These data support the hypothesis that renal and adrenal metabolites enhance varicocele-induced testicular damage. This theory is supported both by hormonal impairment and testicular histological analysis.
