Purpose Inguinal herniorrhaphy is the most common general surgical procedure. It is associated with frequent complications such as recurrence in 2.0% to 14.1% of cases with mesh as well as postoperative hematoma in 4.5% of cases, reduced sensation in 0% to 42.8%, chronic postoperative pain in 5.1%, vasal injury in 0.1% to 0.53% and infection in 3% to 6%. Drawing on our experience with the operating microscope for varicocelectomy, vasectomy reversal and repair of iatrogenic vasal obstruction from hernia repair, we applied the operating microscope for inguinal hernia repair. This study describes the rationale, technique and outcomes of microsurgically assisted inguinal hernia repair. Materials and Methods A total of 291 microsurgically assisted inguinal hernia repairs were performed in 253 men by the same urologist (MG). Simultaneous microsurgical varicocelectomy or other testicular procedures were performed in 83% of cases. All were open repairs through an inguinal incision with the vas deferens, ilioinguinal nerve, genital branch of the genitofemoral nerve, and spermatic vasculature identified and preserved. Median followup was 8.6 months. Outcomes were assessed by examination, pain reporting and pathology reports. Results Chronic postoperative pain, sensory loss, infection, hematoma, vasal injury and recurrence were assessed. The incidence of hematoma was 0.85%. No recurrent hernia, chronic postoperative pain, sensory loss, infection or vasal injury was reported. Conclusions Using an operating microscope the complications of inguinal hernia repair, such as vasal obstruction, testicular atrophy, recurrence, infection, hematoma, chronic postoperative pain and loss of sensation, are minimized. Microsurgically assisted hernia repair is a promising technique, especially when performed by a urologist who simultaneously performs microsurgical varicocelectomy or procedures involving spermatic cord structures or the testis.

Purpose Hydrocelectomy and spermatocelectomy are routine scrotal surgeries. A significant number of the surgical specimens are sent for pathology analysis. However, to our knowledge no study has been done to examine outcomes and necessity, which results in significant potentially unnecessary costs to the patient and the health care system. We evaluated outcomes and surgical pathology analysis of hydroceles and spermatoceles. Materials and Methods We performed a retrospective, single institution chart review of all patients who underwent initial surgery for hydrocele or spermatocele between January 2000 and August 2013. We determined the number of cases in which a surgical specimen was sent for pathology examination. The cost for each specimen was estimated at the department of pathology. Results A total of 264 routine scrotal cases were performed during the 14-year period. Surgical specimens were sent for pathology analysis in 102 hydrocelectomy cases (51%) and in 57 spermatocelectomy cases (90%). No pathology specimen showed any indication of malignancy. The estimated direct total cost of pathology analysis was $49,449 in this cohort. Conclusions No malignancy was detected in 159 hydrocele and spermatocele specimens during the 14 study years, suggesting that the pathology analysis is of little clinical benefit. Forgoing surgical pathology analysis of these specimens would result in significant cost savings to the patient and the health care system. [ABSTRACT FROM AUTHOR]

Purpose: We evaluate whether aspiration and sclerosing of hydrocele testis is an effective treatment. Materials and Methods: Men with symptomatic hydrocele testis were included in this prospective, double-blind, randomized study with polidocanol and placebo. Patients were randomized to active treatment or placebo at the first treatment. Depending on hydrocele testis size (less than 100, 100 to 200 and greater than 200 ml), the patients were treated with 1, 3 or 4 ml polidocanol after aspiration. Patients with recurrence at the 5-week followup received active treatment. Results: A total of 77 patients were included in the study. In group 1 (active treatment) there were 36 patients with a median age of 63 years (range 34 to 92). In group 2, comprised of 41 patients, the median age was 59 years (range 26 to 82). Median followup was 72 months. A significant difference between the groups was observed after the first and second treatments. Recurrence after the first treatment was seen in 16 (44%) patients from group 1 and in 32 (78%) from group 2 (p <0.05). Recurrence after re-treatment with the active drug in both groups was seen in 4 (25%) patients in group 1 and in 14 (44%) in the former placebo group (p <0.05). The overall success rate of treatment in the active group was 89%. There was no difference between the 2 groups in terms of volume of fluid aspirated, symptoms or complications. Conclusions: This long-term efficacy randomized study with placebo showed that polidocanol is effective for the treatment of hydrocele testis with a low recurrence rate. [Copyright &y& Elsevier]

Purpose: We demonstrated that hydrocele aspiration and sclerotherapy with doxycycline is an effective and safe nonsurgical treatment option for hydrocele correction. Materials and Methods: The medical records of patients who underwent hydrocele aspiration and sclerotherapy were analyzed in a retrospective cohort study for success rates as well as improvement in scrotal size and discomfort after a single hydrocele aspiration and sclerotherapy treatment. Patients who reported decreased scrotal size, improved physical symptoms and satisfaction with the procedure were considered as having success with hydrocele aspiration and sclerotherapy. Results: A total of 29 patients (mean age 52.8 years) presenting with 32 nonseptated hydroceles underwent hydrocele aspiration and sclerotherapy with doxycycline between 2005 and 2012. Of the hydroceles 27 (84%) were successfully treated with a single aspiration and sclerotherapy procedure. Overall mean followup was 20.8 months. Three patients reported moderate pain which resolved in 2 to 3 days. Of those patients in whom hydrocele aspiration and sclerotherapy failed, 1 had hydrocele successfully resolved with a second aspiration and sclerotherapy treatment, 3 did not have success with a second procedure and underwent hydrocelectomy, and 1 wanted immediate surgical correction. Conclusions: Hydrocele aspiration and sclerotherapy was successful in correcting 84% of simple nonseptated hydroceles with a single treatment. This result is an increase from previously reported success rates involving a single hydrocele aspiration and sclerotherapy procedure with tetracycline (75%). The success rate of a single hydrocele aspiration and sclerotherapy procedure is similar to the reported success rates involving hydrocelectomy while avoiding the hospital expense and many other complications. We conclude that the hydrocele aspiration and sclerotherapy procedure is a reasonable, nonsurgical and underused treatment option for nonseptated simple hydroceles. [Copyright &y& Elsevier]

Purpose: There is wide variation in the reported incidence of hydrocele after varicocelectomy (0% to 29%). We determined the incidence of hydroceles and hydrocelectomy following adolescent varicocelectomy, the time it took for them to manifest, and the results of aspiration and surgical correction. Materials and Methods: Our adolescent varicocele registry was reviewed to identify patients with a post-varicocelectomy hydrocele. We evaluated physical examination and ultrasound findings, postoperative interval to development and treatment results. Results: A total of 400 patients with at least 6 months of postoperative followup underwent 521 varicocelectomies (16 redo, 1 right, 104 bilateral) from 1987 to 2010. Mean followup was 32 months (range 6 to 182). Hydrocele was detected in 80 of 521 (15.4%) at a mean of 2 years after surgery. The incidence of hydrocele was higher in open vs laparoscopic (p <0.001), bilateral vs unilateral (p = 0.013), nonlymphatic sparing vs lymphatic sparing (p = 0.043) and Palomo vs laparoscopic nonlymphatic sparing (p = 0.001) procedures. Eight patients underwent aspiration for a large postoperative hydrocele. In all 8 patients fluid returned to pre-aspiration status. There were 29 patients (5.6%) who underwent Jaboulay bottleneck hydrocelectomy and none had recurrence. Conclusions: Hydroceles are a common sequela of varicocelectomy, with the fewest hydroceles occurring after laparoscopic lymphatic sparing varicocelectomy. Patients should be followed for at least 2 years after varicocelectomy to examine for the presence of hydroceles. Although there have been reports on the use of aspiration for post-varicocelectomy hydrocele, we have not had success in those with a single aspiration. Jaboulay bottleneck hydrocelectomy had a 100% success rate in this select group. [ABSTRACT FROM AUTHOR]

Purpose: Polidocanol sclerotherapy for hydrocele or spermatocele combines high efficiency with low morbidity, but the optimal dose is not known. We compared the efficacy and morbidity of 2 or 4 ml polidocanol sclerotherapy for hydrocele or spermatocele. Materials and Methods: From 1993 to 2005 a double-blind randomized clinical trial was conducted using 2 or 4 ml polidocanol (30 mg/ml) for sclerotherapy of hydrocele/spermatocele in 224 evaluable patients at 3 university hospitals. Fluid was evacuated and 2 or 4 ml polidocanol was administered by a nurse, with the amount injected concealed from others present. At 3-month followup morbidity was ascertained using a questionnaire completed by the patients. Fluid recurrence was determined clinically and generally re-treated. Results: After the first treatment, cure was observed in 59% and 47% in the 4 and the 2 ml group, respectively (p = 0.04). More patients in the 4 ml group had complications (31% vs 18%, p = 0.04). Complications were mostly of low or moderate intensity and seldom required medication. After 1 to 4 treatments 200 of 224 patients (89%) were cured and another 10 (5%) had small amounts of residual fluid, with no difference between the groups. Of the patients with hydroceles/spermatoceles larger than 175 ml, 58% and 34% were cured after the first treatment in the 4 and 2 ml groups, respectively (p = 0.012), with no differences in complications between the groups. Conclusions: Polidocanol sclerotherapy was effective for the treatment of hydrocele or spermatocele in our patients, with 94% satisfactory results after 1 to 4 treatments. A dose of 4 ml was superior to 2 ml, particularly for larger hydroceles/spermatoceles. [Copyright &y& Elsevier]

Purpose: Varicocelectomy after previous inguinal surgery poses a potential risk of testicular volume loss. To assess the extent to which varicocelectomy can be done without the complication of ipsilateral testis atrophy we present outcomes in adolescent patients with a history of inguinal surgery who underwent ipsilateral varicocelectomy. Materials and Methods: We retrospectively reviewed patient data from a single urologist practice. Testicular volume was recorded preferentially by ultrasound or, when unavailable, by ring orchidometry. Testicular asymmetry was calculated using the formula, [(right testis volume − left testis volume)/right testis volume] × 100. Symmetry was defined as less than 10% asymmetry. Catch-up growth was defined as resolution of asymmetry. Results: We identified 22 adolescent patients who fit study criteria. The patients underwent a total of 25 varicocelectomies since 3 underwent bilateral repair after previous bilateral inguinal surgery. Initial inguinal surgery included inguinal herniorrhaphy, hydrocelectomy and orchiopexy. Varicocelectomy was done laparoscopically in 17 cases and via open technique in 8 with variations in preservation/sacrifice of the lymphatics and artery. Median ± SD followup was 24.2 ± 18.2 months. After varicocelectomy mean testicular asymmetry decreased from 27.6% to 10.5%. There was no incidence of testicular atrophy postoperatively. The incidence of catch-up growth was 43% with no difference between the artery sparing and the nonartery sparing technique. Conclusions: Varicocelectomy with a history of previous inguinal surgery is safe and provides a significant incidence of testicular catch-up growth. Artery sparing vs sacrificing technique did not make a difference in terms of catch-up growth. [Copyright &y& Elsevier]

Purpose: We systematically reviewed the results of varicocelectomy by Palomo procedure in children and adolescents. Materials and Methods: We performed a search of the English literature through the MEDLINE® database and the Cochrane Central Search library. The key words used were “varicocele and children” and “varicocele and adolescents.” Of 264 articles published with data on varicocele surgery in children and adolescents 27 concerned the classic Palomo procedure and 20 dealt with the modified Palomo technique, in which the testicular artery was spared. Laparoscopic Palomo varicocelectomy was compared with the open Palomo technique. Results: Totals of 1,344 and 496 patients were treated with the laparoscopic and open Palomo techniques, respectively. The rates of hydrocele in the open and laparoscopic groups were 9.7% and 6.9%, respectively (p = 0.81). The rate of recurrence was 2.9% in the open group and 4.4% in the laparoscopic group (p = 0.146). A modified Palomo procedure was used in 715 operations and the classic technique in 1,454. Hydrocele was diagnosed in 3.2% of patients in the modified group and 7.7% in the classic group (p <0.001). Varicocele recurred in 4.2% of patients undergoing the modified procedure and 3.4% of those undergoing the classic procedure (p = 0.506). Mean ± SD testicular catch-up growth was 54.7% ± 38.9% in the modified group and 66.7% ± 19.9% in the classic group (p = 0.584). Three studies documented improvement of the quality of semen examination postoperatively compared to a control group of uncorrected cases. No study evaluated the rate of fertility after varicocelectomy. Conclusions: The rate of hydrocele is high with the classic Palomo technique and less with the modified technique. The rate of varicocele recurrence is around 3% to 4% with both procedures. The percentage of testicular catch-up growth is variable. [Copyright &y& Elsevier]

Purpose: Standard surgical procedures for hydrocele may cause postoperative discomfort, temporary limitation of normal activities and complications, such as hematoma, infection, persistent swelling, chronic pain and decreased fertility. We describe a new technique in an effort to decrease these complications. Materials and Methods: Between April 2004 and December 2006, 21 patients underwent hydrocelectomy, which was bilateral in 1. Through a 15 mm transverse scrotal incision the tunica vaginalis parietalis was identified and grasped. Under gentle traction the sac was dissected bluntly and delivered out of the incision. The fully mobilized tunica was excised by electrocautery at its base, followed by wound closure. Patients were discharged home within 24 hours after surgery and were followed at 6-month intervals for a minimum of 18 months. Results: Mean operative time was 27.3 minutes. Postoperatively hematoma or wound infection was not evident in any case. Mild scrotal edema usually subsided within a few days after the procedure. Two patients with persistent edema and hardening of the scrotum required additional bed rest and anti-inflammatory agents. Patients were able to resume normal daily activity an average of 6 days after surgery (range 3 to 21). Cure was achieved in 21 of the 22 hydrocele cases (95%). Conclusions: Our pull-through technique enables the surgeon to remove large hydrocele sacs through a small incision and with minimal dissection under direct vision of the testicular structures, resulting in early recovery and minimal complications. This procedure may be a viable option for the surgical management of idiopathic hydrocele. [Copyright &y& Elsevier]

Purpose: Infantile abdominoscrotal hydrocele is a rarely described condition. We report the outcome of the largest single institution experience managing these lesions. Materials and Methods: We retrospectively reviewed descriptive case series of all infants treated between January 1998 and December 2007. Postoperative followup ranged from 3 to 107 months (median 48). Results: A total of 18 consecutive patients underwent abdominoscrotal hydrocele repair at age 3 to 21 months (median 8). The first 13 patients underwent inguinal hydrocelectomy, which consisted of high ligation of the processus vaginalis and complete excision of the abdominal component of the lesion. The remaining 5 patients underwent plication of the tunica vaginalis accomplished through the scrotum. Included in this group were 2 patients initially treated expectantly because the lesion was without undue tension at diagnosis. Both cases demonstrated spontaneous resolution of the abdominal component of the lesion but ultimately required surgery for scrotal hydrocele. Overall 23 testes (5 bilateral lesions) were operated on, of which 18 had some degree of testicular dysmorphism detected by ultrasonography or during surgery and 15 fully recovered postoperatively. A total of 11 patients experienced 1 or more postoperative complications, including persistent scrotal swelling (7), hypoplastic testis (3), scrotal hematoma (2), inguinal hernia (1) and cryptorchidism (1). Morbidity related to scrotal hydrocelectomy was negligible. There were no recurrences of abdominoscrotal hydrocele in the series. Conclusions: Tense infantile abdominoscrotal hydroceles are associated with a high rate of testicular dysmorphism, which is often reversed by early intervention. Simple transscrotal plication of the tunica vaginalis represents an effective procedure with decreased postoperative complications. [Copyright &y& Elsevier]

Purpose: Abdominoscrotal hydrocele is a poorly understood entity and multiple theories attempt to explain its occurrence. To our knowledge the factors contributing to the formation of abdominoscrotal hydrocele are unknown, as are its cellular, biochemical and hydrostatic properties. We prospectively evaluated abdominoscrotal hydrocele at surgery to define its cause and its effects on the testicle. Materials and Methods: Six patients (9 abdominoscrotal hydroceles) were prospectively evaluated at surgery. Hydrocele volume was recorded as well as simultaneous hydrocele and bladder pressure. Fluid at surgery was sent for biochemical and cellular analysis. Testicular and epididymal abnormalities were noted and testicular length was measured. All abdominoscrotal hydroceles were exteriorized and excised. Processus vaginalis patency was documented at repair. Results: Mean patient age was 7.17 months (range 5 to 12). The mean volume recorded was 212.78 ml (range 80 to 320). Mean corrected hydrocele pressure was 15.44 cm H2O (range 7 to 28). Mean testicular length was 3.6 cm (range 2.2 to 5.5). All patients had epididymal anomalies and 2 of the 3 unilateral abdominoscrotal hydroceles had abnormal contralateral scrotal findings. In no case was a peritoneal communication identified. Fluid analysis revealed a high protein concentration (mean 4.94 gm/dl), low triglyceride concentration (mean 20.29 mg/dl) and lactate dehydrogenase levels comparable to those in normal serum (mean 99.14 U/l). Cytological analysis revealed a sterile, low cellularity fluid with a macrophage predominance (mean 84.71%). Conclusions: Abdominoscrotal hydrocele occurs as a result of increased intraluminal pressure confined in a proximal closed processus vaginalis. Increased hydrocele pressure allows expansion into the retroperitoneal space through the internal inguinal ring. This increased pressure is associated with testicular elongation and epididymal abnormalities. The exudative fluid is of a noninfectious etiology and it suggests an altered filtration process. To our knowledge the effects on future fertility are unknown. [Copyright &y& Elsevier]

Purpose: We report our long-term experience with the Palomo technique for varicocele ligation in the pediatric population. Materials and Methods: Between August 1986 and December 2006, 312 patients 7 to 21 years old (median age 14.6) underwent varicocele ligation using the Palomo technique for complete retroperitoneal ligation of the internal spermatic veins and artery. In 234 patients the varicocele was grade III, in 75 it was grade II and in 3 it was grade I. Indications for surgery were relative left testicular volume loss compared to the right testicle in 248 patients, bilateral palpable varicoceles in 8 and pain or parental preference in the remainder. Postoperative followup was 2 weeks to 10.6 years (mean 17.4 months). A total of 233 patients had at least a 6-month followup. Results: Persistent varicocele was noted in 9 of 233 patients (3.9%). Of the 233 patients 68 (29%) presented with a secondary hydrocele an average of 14 months (range 18 to 1,964 days) following surgery, of whom 12 (17.6%) underwent hydrocele correction. The 12 patients who underwent hydrocelectomy represented 5% of the patients with varicocelectomy. Postoperative testicular atrophy was not documented in any patient and no other surgical complications were noted. Conclusions: The Palomo procedure for adolescent varicocele repair is safe and effective with a high success rate and low complication rate. Postoperative hydrocele formation developed in 29% of our patients. However, most secondary hydroceles were small, asymptomatic and did not require surgical correction. [Copyright &y& Elsevier]

Purpose: The most common complications of varicocelectomy include failure and hydrocele formation. Various surgical approaches have been used to minimize complications and guarantee durable results. The use of vital dyes to visualize and preserve testicular lymphatics intraoperatively has been proposed to reduce the incidence of hydrocele formation. We investigated the safety of intratesticular injection of various vital dyes and their efficacy in allowing visualization of lymphatics for varicocelectomy. Materials and Methods: Using general anesthesia, 22 adolescent rats underwent bilateral transscrotal intratesticular injection of methylene blue, isosulfan blue, trypan blue or normal saline. All rats with intratesticular injection of a vital dye underwent immediate exploration of the spermatic cord to observe for visualization of lymphatic vessels. At 3 months all rats were euthanized, and orchiectomy was performed for histological examination. Results: Spermatic cord lymphatic vessels were variably visualized depending on concentration and volume of the vital dye used. Histological examination of the testicles at 3 months after injection revealed areas with necrosis of seminiferous tubules, thickened tubular basement membranes, interstitial fibrosis and hyalinization, and striking intratubular dystrophic calcification. These pathological changes were present to varying degrees in all groups. Conclusions: Although spermatic cord lymphatic channels were successfully visualized to varying degrees, intratesticular injection of vital dyes (and even normal saline) produced pathological changes in all groups, despite variation of concentration, volume and type of vital dye. Intratesticular injection of vital dyes for the visualization of lymphatics during varicocelectomy should be abandoned. Paratesticular injection of vital dyes should be used with caution.
