Paratesticular metastasis from colorectal adenocarcinoma presenting as hydrocele: a rare case report and literature review.

Colorectal cancer, with the liver being the most common site of distant metastasis, followed by the lungs and bones. Although reports of metastasis to the testis exist, paratesticular metastasis is extremely rare. A 37-year-old male presented with scrotal swelling. Ultrasound revealed hydrocele of the tunica vaginalis. The patient underwent routine surgical treatment, and postoperative pathology of the tunica vaginalis indicated adenocarcinoma of gastrointestinal origin. Colonoscopic biopsy confirmed adenocarcinoma of the sigmoid colon. After six months of systemic therapy, tumor reduction surgery was performed in conjunction with tunica vaginalis excision. Postoperative pathology suggested histological similarity in both sites, with immunohistochemistry results supporting the diagnosis of sigmoid colon adenocarcinoma metastasizing to the tunica vaginalis. We conducted a literature review, summarizing and discussing clinical presentations, metastatic pathways, and diagnostic approaches.

Well-Differentiated Papillary Mesothelial Tumor of the Scrotum with Suspicious Invasion.

Well-differentiated papillary mesothelial tumor (WDPMT) is a distinct form of mesothelioma with low malignant potential and is mostly found in the peritoneal cavity. It consists of mesothelial cells with papillary structure and bland cytology. We report a rare case of WDPMT with suspicious invasive foci in the tunica vaginalis. WDPMT with invasive foci is known to have a tendency for recurrence. Therefore, careful attention should be given to properly diagnosing and treating this rare entity.

Aspiration and sclerotherapy versus hydrocelectomy for treating hydroceles: a systematic review and meta-analyses.

BACKGROUND: In this meta-analysis, we aimed to compare the hydrocelectomy versus aspiration and sclerotherapy for treating primary hydrocele. METHODS: We included randomized controlled trials (RCTs) and quasi-RCTs that compared aspiration and sclerotherapy with any type of sclerosants versus hydrocelectomy for primary hydrocele. Studies were identified via a systematic search of the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and ClinicalTrials.gov. Citation tracking of related articles was performed. Data extraction and quality assessment were performed independently by two authors. The primary and secondary outcome measures were compared and analyzed using the Review Manager 5.3.5 software. RESULTS: Five small RCTs were included in the present study. These 5 RCTs included 335 patients with 342 hydroceles, randomized to aspiration and sclerotherapy (185 patients; 189 hydroceles) and surgery (150 patients; 153 hydroceles). There was no significant difference in clinical cure between sclerotherapy and hydrocelectomy (RR 0.45, 95% CI 0.18 to 1.10). Meta-analysis revealed a significant increase in recurrence in the sclerotherapy group compared with the surgical group (RR 9.43, 95% CI 1.82 to 48.77). There were no significant differences between the two groups in assessing fever, infection, and hematoma. CONCLUSION: Aspiration and sclerotherapy is an efficient technique with a higher recurrent rate; therefore, we recommend aspiration and sclerotherapy for patients at high risk for surgery or avoiding surgery. In addition, included RCTs had low methodological quality, low sample size, and invalidated instruments for outcome assessment. Therefore, there is a great need for further methodologically rigorous RCTs with the registered protocol.

Metachronous Contralateral Occurrence of Hydrocele After Unilateral Hydrocelectomy in Children Younger Than 8 Years.

BACKGROUND: Hydrocele on the contralateral side after surgical repair is an uncommon condition compared to surgical site recurrence. Although there has been much research on metachronous contralateral inguinal hernia in children, metachronous contralateral hydrocele, which share a common pathology with inguinal hernias, has not yet been investigated. We have investigated the incidence and risk factors for metachronous contralateral occurrence of communicating and noncommunicating hydroceles in children younger than 8 years. METHODS: From January 2017 to June 2020, 302 children younger than 8 who were diagnosed with unilateral hydroceles were treated in our hospital without surgical exploration of contralateral hydrocele. The disease was classified into communicating and noncommunicating hydroceles. We divided patients into two groups according to the presence of metachronous contralateral hydrocele and analyzed the differences between the two groups. RESULTS: Among 302 patients, the mean age was 36.4 ± 20.9 months. Metachronous contralateral hydrocele occurred in 15 (4.9%) patients as communicating hydroceles. Comparison between the two groups showed statistically significant differences in type of hydrocele (P = 0.047) at first diagnosis. CONCLUSION: Clinically evident risk of metachronous contralateral hydrocele after unilateral hydrocelectomy was 4.9%. Despite the relatively low incidence rate, the risk of metachronous contralateral occurrence should always be consulted with parents before surgical treatment of hydroceles.

Clinical efficacy of minimal hydrocelectomy with the aid of scrotoscope in the treatment of testicular hydrocele / 现代泌尿外科杂志

【Objective】 To explore the application value of scrotoscopy in the treatment of testicular hydrocele. 【Methods】 The clinical data of 27 patients with testicular hydrocele who were successfully treated with minimal hydrocelectomy with the aid of scrotoscope (MHS group) and 32 patients with traditional open surgery (TH group) during Dec.2017 and Dec.2021 were retrospectively analyzed and compared. 【Results】 Compared with TH group, the MHS group needed shorter average operation time [(32.22±5.25) min vs.(57.34±8.71) min, P<0.01], shorter incision length [(0.95±0.15) cm vs.(5.09±0.55) cm, P<0.01], shorter hospital stay [(3.63±0.97) d vs.(4.72±0.89) d,P<0.01] and lower postoperative incision visual analogue scale (VAS) (P<0.01), and milder degree of edema on the 3rd and 7th day after operation (P<0.05), but higher recurrence rate (14.81% vs.3.13%, P=0.256) 24 weeks after operation. 【Conclusion】 Scrotoscopy is safe in the treatment of testicular hydrocele, which has the advantages of short operation time, small incision, mild postoperative incision pain, mild scrotal edema and short hospital stay, but the recurrence rate tends to be higher than that of traditional open surgery.

Spontaneous, atraumatic hydrocele rupture: A case report.

There is little information in the literature on the management and prognosis of ruptured hydroceles. We present a case report of spontaneous, atraumatic left hydrocele rupture in a 64-year-old male. His hydrocele was initially diagnosed as non-complex and appeared to have ruptured spontaneously three years after initial onset. On follow-up in clinic, mild re-accumulation of fluid was observed, and no pain was reported by the patient. Post-rupture fluid re-accumulation was minimal in our patient but there is potential for significant fluid re-accumulation based on other reports of ruptured hydroceles.

Abdominoscrotal Haematocele in an Adult and Its Successful Treatment.

Abdominoscrotal hydrocele (ASH) is a variant of hydrocele that rarely occurs in adults. ASH has two sacs, one in the scrotum and one in the abdomen connected through the inguinal canal. Abdominoscrotal haematocele is a rare complication of ASH. We report a 57-year-old male patient who presented to a tertiary care hospital in Puducherry, India, in 2019 with complaints of swelling in the scrotum for 15 years and abdominal pain for two months. Both the swellings were soft and cross fluctuation was present. Imaging confirmed the diagnosis of ASH. During a diagnostic laparoscopy, the abdominal sac was decompressed and found to have thick brownish fluid suggestive of haematocele. It was demonstrated that both sacs were connected. Due to difficulty in the dissection of the sac, the procedure was converted to an open procedure. Both the sacs were excised and Lytle's repair was done for the dilated internal ring. The patient recovered and no recurrence of any swelling in the abdomen or scrotum was found at the end of a one-year follow-up.

Adolescent Varicocelectomy: Success at What Cost? Clinical Outcome and Cost Comparison of Surgical Ligation and Percutaneous Embolization.

Objectives: Evaluate clinical outcome, recurrence, morbidity, and cost associated with laparoscopic surgical ligation versus percutaneous embolization of adolescent varicocele. We hypothesize that both approaches are similar in outcomes, complications, and cost. Materials and Methods: A retrospective review of 56 consecutive adolescent males, ≤18 years from 2006 to 2016 with clinical varicocele who underwent laparoscopic surgical ligation or percutaneous embolization. Patient demographics, operative time, postoperative complications, success, varicocele grade, recurrence, and hospital charges were abstracted. Results: Mean age was 14.2 ± 2.1 years; 48 (86%) patients having undergone laparoscopic surgical ligation and 8 (14%) percutaneous embolization. Intervention in 45 (80%) patients was for testicular hypotrophy (mean 27.4% ± 15.6%) and 11 (20%) for pain symptomology. Median follow-up was 17.5 months (range 1-65 months). After ligation, 2 (4%) patients developed hydroceles (1 with subsequent hydrocelectomy) and 6 (12%) varicocele recurrence. There were no cases of hydrocele or varicocele recurrence after percutaneous embolization. Twenty ligation patients had postoperative scrotal ultrasound demonstrating an increase in testicular volume by a reduction in difference in testicular volume from 27.3% ± 14.7% preoperatively to 11.2% ± 13.6% postoperatively (P < .001). There was significant difference in mean operative time between the groups (surgical ligation 41.3 minutes versus percutaneous embolization 117.9 minutes, P < .001) and hospital charges for the procedure (surgical ligation $3983 versus percutaneous embolization $18.165, P < .001). Conclusions: Contrary to our hypothesis, percutaneous embolization has seemingly lower rates of postoperative hydrocele and varicocele recurrence in comparison to surgical ligation but with three times the exposure to general anesthesia and at four times the price.

Complications after scrotal surgery - still a major issue?

OBJECTIVE: Gold standard treatment of symptomatic hydrocele or spermatocele is surgery. Despite a minor procedure, complications such as bleeding and infections leading to reoperations may be devastating for the patients. In autumn 2018, an accumulation of complications was seen in our department. The aim of this study was to investigate the rate and grade of complications and to identify potential means to reduce these. MATERIALS AND METHODS: Patient records of all patients undergoing surgical repair of hydrocele or spermatocele from December 2017 to November 2018 were examined. Results were audited to identify potential causes of complications. The focus was on the perioperative hemostasis and postoperative activity restrictions. The outcome was compared to a consecutive patient series operated the following year. RESULTS: Sixty-five men were operated on during the first period. Twenty-two patients contacted the department postoperatively due to swelling or pain, 19 patients were examined at the hospital and six patients were re-operated 1-9 times. The following year, 69 patients were operated on. Of these, 16 patients contacted the department postoperatively (p = 0.17), 13 patients were examined at the hospital, and five patients were re-operated (p = 0.68). There was the same complication rate in patients operated by specialist urologists or supervised younger doctors. However, patients preoperatively examined and informed by a specialized urologist had significantly fewer complications compared to those informed by urological residents and interns (p = 0.012). CONCLUSION: Despite the change in patient information and increased awareness of possible complications, a high proportion of patients still were in need of unplanned contact to the department and reoperation.

Comparison of outcomes and costs of surgery versus sclerotherapy to treat hydrocele / Comparação entre resultados e custos de cirurgia e de escleroterapia para tratamento de hidrocele

ABSTRACT Objective: To evaluate the outcomes and costs associated with surgery versus sclerotherapy as treatment of hydroceles. Methods: A total of 53 men consecutively treated for hydrocele at our organization, between December 2015 and June 2019, were retrospectively analyzed (39 with Jaboulay technique and 14 with sclerotherapy). All charts were reviewed, assessing clinical data, ultrasound findings, surgical data, and post-procedure outcomes. The hospital finance department calculated the cost of outpatient evaluation, complementary tests, supplies, drugs, and professionals' costs throughout all procedures. Results: The median age for both groups was similar (58 and 65 years old). Comorbidities were less frequent in the Surgery Group (20; 51%) than in the Sclerotherapy Group (14; 100%, p<0.05). The median length of hospital stay was 34.5±16.3 hours for the Surgery Group and 4 hours for the Sclerotherapy Group. The mean follow-up period was similar for both groups (85.4±114.8 days after surgery, and 60.9±80.1 days after sclerotherapy, p=0.467). No significant complications occurred in any patient. Success rates were 94.8% after surgery and 92.8% after sclerotherapy. The mean cost per patient was US$2,558.69 in the Surgery Group (Hydrocelectomy Group) and US$463.58 in the Sclerotherapy Group (p<0.0001). Costs directly related to in-hospital treatment procedures were significantly higher for surgery versus sclerotherapy (US$2,219.82±US$1,629.06 versus US$130.64±US$249.60; p<0.0001). Conclusion: Sclerotherapy is an excellent treatment option for idiopathic hydrocele as compared to traditional Jaboulay. It has a high success rate, low complication rates, fast discharge and patients return quicker to activities of daily living.

RESUMO Objetivo: Avaliar resultados e custos associados à cirurgia e à escleroterapia como tratamentos das hidroceles. Métodos: Foram tratados consecutivamente para hidrocele em nossa instituição 53 homens, entre dezembro de 2015 e junho de 2019, os quais foram analisados retrospectivamente (39 pela técnica de Jaboulay e 14 por escleroterapia). Todos os prontuários foram revisados, avaliando dados clínicos, achados de ultrassom, dados cirúrgicos e desfechos pós-procedimento. O departamento financeiro do hospital calculou o custo da avaliação ambulatorial, dos exames complementares, dos insumos, dos medicamentos e dos profissionais em todos os procedimentos. Resultados: A idade mediana foi semelhante nos dois grupos (58 e 65 anos). Comorbidades foram menos frequentes no Grupo Cirurgia (20; 51%) do que no Grupo Escleroterapia (14; 100%; p<0,05). O tempo mediano de internação hospitalar foi 34,5±16,3 horas para o Grupo Cirurgia e 4 horas para Grupo Escleroterapia. O período médio de seguimento foi semelhante nos dois grupos (85,4±114,8 dias após a cirurgia e 60,9±80,1 dias após escleroterapia; p=0,467). Nenhuma complicação significativa ocorreu nos pacientes. As taxas de sucesso foram de 94,8% após a cirurgia e 92,8% após a escleroterapia. O custo médio por paciente foi de US$2,558.69 para Grupo Cirurgia e US$463.58 para Grupo Escleroterapia (p<0,0001). Os custos relacionados aos procedimentos de tratamento hospitalar foram significativamente maiores para cirurgia em relação à escleroterapia (US$2,219.82±US$1,629.06 versus US$130.64±US$249.60; p<0,0001). Conclusão: A escleroterapia é uma excelente opção de tratamento para hidrocele idiopática em comparação com a tradicional Jaboulay. Apresenta alta taxa de sucesso, baixas taxas de complicações e alta rápida, além de os pacientes retornarem mais rapidamente às atividades diárias.

Testicular schistosomiasis mimicking hydrocele in a child: a case report.

Schistosomiasis is a disease of profound public health importance worldwide. Testicular schistosomiasis (TS) is however still considered as a rare entity despite the burden of the disease. We report a case of a 9 year old male who presented with features suggestive of testicular hydrocele. The spermatic cord and testis were seen as thickened lesion on examination and a biopsy taken revealed calcified ova of Schistosoma haematobium. This is being reported to enhance increased suspicion amongst surgeons in cases of testicular masses within endemic settings like Nigeria.

Individualized minimally invasive treatment for adult testicular hydrocele: A pilot study.

BACKGROUND: Hydrocelectomy is the gold standard for the treatment of hydrocele, but it often causes complications after surgery, including hematoma, infection, persistent swelling, hydrocele recurrence, and chronic pain. In recent years, several methods for minimally invasive treatment of hydrocele have been introduced, but they all have limitations. Herein, we introduce a new method of individualized minimally invasive treatment for hydrocele. AIM: To present a new method for the treatment of adult testicular hydrocele. METHODS: Fifty-two adult patients with idiopathic testicular hydrocele were included. The key point of this procedure was that the scope of the resection of the sheath of the tunica vaginalis was determined according to the maximum diameter (d) of the effusion measured by ultrasound and the maximum diameter of the portion of the sheath pulled out of the scrotum was approximately πd/2. The surgical procedure consisted of a 2-cm incision in the anterior wall of the scrotum, drainage of the effusion, and dissection of part of the sheath of the tunica vaginalis. After the sheath was peeled away to the predetermined target extent, the pulled-out sheath was removed. The intraoperative findings and postoperative complications were analyzed. RESULTS: All patients were successfully treated with a median operation time of 18 min. The median maximum diameter of the effusion on ultrasound was 3.5 cm, and the median maximum diameter of the resected sheath was 5.5 cm. Complications occurred in four (7.7%) patients: two (3.8%) cases of mild scrotal edema, one (1.9%) case of scrotal hematoma, and one (1.9%) case of wound infection. All of the complications were grade I-II. Recurrent hydrocele, chronic scrotal pain, and testicular atrophy were not observed during a median follow-up of 12 mo. CONCLUSION: We report a new technique for individualized treatment of testicular hydrocele, which is quantitative and minimally invasive and yields good outcomes. Further study is warranted to verify its potential value in clinical practice.

Epidemiology of hydrocele and spermatocele; incidence, treatment and complications.

Objectives: To estimate the incidence of men seeking specialized care and receiving treatment for hydro or spermatocele complaints. Also, to determine the risk of complications of treatment. Materials and methods: The total number of men living in Sweden each year from 2005 to 2014 was used to calculate incidence and age distribution of adult (≥18 years) men seeking specialized healthcare with either hydro or spermatocele. This was done by using nationwide registries, mandatory by law. They contain information on primary or discharge diagnosis, procedure codes and antibiotic prescriptions. Also, complication rates comparing aspiration (with or without sclerotherapy) and conventional surgery were analysed. Results: The incidence of men with either hydro or spermatocele diagnosis in specialized healthcare was ∼100/100,000 men. The treatment incidence was 17/100,000 men. Orchiectomy was used as primary treatment in 2.4% of cases. The risk of experiencing a complication was clinically and statistically significantly increased with conventional surgery as compared with aspiration, 17.5% (1607/9174) vs 4.6% (181/3920), corresponding to relative risk of 3.79 (95% CI = 3.27-4.40). Hematoma and infections were the most common complications. Conclusion: Hydro and spermatoceles are common, affecting elderly men. Aspiration seems advantageous with respect to complications and can be recommended due to the benign course of the disease. The indication for conventional surgery might be questioned such as the use of orchiectomy as primary treatment.

Hidrocele como manifestación inicial de tuberculosis genitourinaria y miliar / Hydrocele as initial manifestation of genitourinary and miliary tuberculosis / Hidrocele como manifestação inicial da tuberculose geniturinária e miliar

Introducción. La tuberculosis es una enfermedad infectocontagiosa que puede afectar cualquier órgano del cuerpo, incluyendo el sistema genitourinario, representando el 33.7-45.5 % de las tuberculosis extrapulmonares. El objetivo de este trabajo es reportar el caso de un paciente con hidrocele como manifestación inicial de tuberculosis genitourinaria y miliar, enfermedad que no se sospechaba. Presentación del caso. Paciente masculino previamente sano, que consulta a urgencias por orquialgia e hidrocele bilateral, con secreción purulenta por escroto, requiriendo manejo antibiótico intravenoso e hidrocelectomía derecha, con hallazgos intraoperatorios de engrosamiento del epidídimo derecho, y drenaje de material caseoso y purulento. Se realizó epididimectomía ipsilateral, se solicitaron pruebas de detección de bacilos tuberculosos en espécimen y derivado proteico purificado, que fueron positivas. En el postoperatorio presentó sintomatología respiratoria; paraclínicos evidenciaron compromiso pulmonar, pleural y de la vía urinaria por bacilos tuberculosos. Se inicia manejo antituberculoso con evolución satisfactoria. Discusión. El genitourinario es considerado el segundo sistema con mayor afectación de tuberculosis extrapulmonar. El órgano más afectado es el riñón (en un 80 % con respecto a los demás) y el órgano genital es el epidídimo (22 - 55 %). Debe sospecharse en pacientes con síntomas urinarios crónicos sin causa aparente. Se asocia a una alta tasa de morbimortalidad por infertilidad y falla renal. Conclusiones. A pesar de su sintomatología inespecífica y de tratarse de una entidad poco sospechada, la tuberculosis genitourinaria debe descartarse al existir tuberculosis pulmonar. Su diagnóstico y tratamiento oportuno serán de gran importancia para evitar complicaciones secundarias. Cómo citar: Álvarez-Jaramillo J, Ortiz-Zableh AM, Tarazona-Jiménez P, Ortiz-Azuero A.

Introduction. Tuberculosis is an infectious disease that can affect any organ in the body, including the genitourinary system, which accounts for 33.7 - 45.5 % of non-pulmonary tuberculosis cases. The purpose of this paper is to report a case of hydrocele as initial manifestation of genitourinary and miliary tuberculosis, which was an unsuspected disease. Case Presentation. Previously healthy male patient is admitted to emergencies due to orchialgia and bilateral hydrocele, with purulent secretion from the scrotum. Was managed with intravenous antibiotic and right hydrocelectomy. Intraoperative findings of thickening of right epididymis and drainage of caseous and purulent material. Ipsilateral epididymectomy was performed; testing for detection of tubercle bacillus in specimen and purified protein derivative was requested, and was found positive. In the postoperative period, respiratory symptoms arose; paraclinical tests found compromised lungs, pleura and urinary tract by tubercle bacillus. Antituberculous treatment was initiated with satisfactory evolution. Discussion. The genitourinary system is the second-most affected system by nonpulmonary tuberculosis. The most affected organ is the kidney (by 80 % compared to the others) and the most affected genital organ is the epididymis (22 - 55 %). It should be suspected in patients with chronic urinary symptoms with no apparent cause. It is associated with a high rate of morbidity and mortality due to infertility and kidney failure. Conclusions. Despite the non-specific symptoms and because it is not normally a suspected entity, genitourinary tuberculosis should be ruled out when pulmonary tuberculosis exists. Timely diagnosis and treatment are very important in order to prevent secondary complications. Cómo citar: Álvarez-Jaramillo J, Ortiz-Zableh AM, Tarazona-Jiménez P, Ortiz-Azuero A.

Introdução. A tuberculose é uma doença infecciosa que pode afetar qualquer órgão do corpo, incluindo o sistema geniturinário, representando 33.7 a 45.5 % da tuberculose extrapulmonar. O objetivo deste trabalho é relatar o caso de um paciente com hidrocele como uma manifestação inicial de tuberculose geniturinária e miliar, uma doença que não se suspeitava. Apresentação do caso. Paciente do sexo masculino previamente saudável, que consultou a emergência para orquialgia e hidrocele bilateral, com secreção purulenta do escroto, necessitando de tratamento antibiótico endovenoso e hidrocelectomia direita, com achados intraoperatórios de espessamento do epidídimo direito e drenagem de material purulento e caseoso. Foi realizada uma epididimectomia ipsilateral e foram solicitados exames de bacilos tuberculosos em espécime e derivado proteico purificado, que foram positivos. No pós-operatório, apresentou sintomas respiratórios; testes para-clínicos mostraram comprometimento pulmonar, pleural e do trato urinário devido a bacilos da tuberculose. Começa-se o tratamento antituberculose com evolução satisfatória. Discussão. O sistema geniturinário é considerado o segundo com maior comprometimento da tuberculose extrapulmonar. O órgão mais afetado é o rim (80 % em relação aos demais) e o órgão genital é o epidídimo (22 a 55 %). Deve-se suspeitar em pacientes com sintomas urinários crônicos sem causa aparente. Está associada a uma alta taxa de morbimortalidade devido à infertilidade e insuficiência renal. Conclusões. Apesar de sua sintomatologia inespecífica e de ser uma entidade pouco suspeitada, a tuberculose geniturinária deve ser descartada quando existir tuberculose pulmonar. Seu diagnóstico e tratamento oportuno serão de grande importância para evitar complicações secundárias. Cómo citar: Álvarez-Jaramillo J, Ortiz-Zableh AM, Tarazona-Jiménez P, Ortiz-Azuero A.

Hydrocelectomy via scrotal incision is a valuable alternative to the traditional inguinal approach for hydrocele treatment in boys.

Purpose: Few studies have explored the treatment of isolated communicating hydroceles via scrotal incision. We prospectively evaluated the surgical outcomes of such treatment in boys with hydroceles compared with that using traditional, inguinal incision hydrocelectomy. Materials and Methods: Of 347 boys aged 0-12 years who were diagnosed as hydrocele on ultrasonography, 173 boys were assigned to the scrotal incision hydrocelectomy group (group I, n=173) and 172 boys were assigned to the traditional inguinal incision hydrocelectomy group (group II, n=172), and finally 156 boys in group I and 156 boys in group II were included in this study. Surgical outcomes, including postoperative complications and hydrocele relapse rates, were compared between groups. Results: The overall success rates were similar in both groups (group I, 96.8%; group II, 89.1%; p=0.740). The operation time and hospital stay were significantly shorter in group I (30.94±3.95 minutes and 3.94±0.30 days) than in group II (38.02±7.12 minutes and 4.24±0.99 days; p<0.001 and p=0.009, respectively). The postoperative complication rate was lower in group I than in group II (3.2% vs. 10.9%, p=0.740). Conclusions: Scrotal incision hydrocelectomy in boys was associated with shorter operative time and hospital stay, and a lower postoperative complication rate, than was the inguinal incision approach. The scrotal incision technique might be an easy and effective alternative treatment when used to treat hydroceles in boys as well as inguinal incision approach.

Is genetic drift to blame for testicular dysgenesis syndrome in Semliki chimpanzees (Pan troglodytes schweinfurthii)?

BACKGROUND: We present 3 likely cases of testicular dysgenesis syndrome (TDS) within a community of chimpanzees (Pan troglodytes schweinfurthii). We tested whether genetic drift may be the culprit, as a genetic cause has been suspected to account for TDS among other wildlife. METHODS: We successfully sequenced a 367-bp segment spanning the first hypervariable region within the D-loop of the mitochondrial genome for 78 DNA samples. RESULTS: We found 24 polymorphic sequence sites consisting of 7 singletons and 17 parsimony informative sites. This sample contained 9 haplotypes with a diversity index of 0.78 (SD = 0.03). All tests against the null hypothesis of neutral polymorphisms were non-significant (P > .10). The mismatch distribution of pairwise differences does not fit a Poisson's curve (raggedness index = 0.166; SSD = 0.12; P = 1). CONCLUSIONS: Thus, we found no significant signs of genetic isolation, population expansion, or genetic bottleneck. Alternative causes of TDS and how they might pertain to this population are discussed.

Microsurgically Assisted Inguinal Hernia Repair and Simultaneous Male Fertility Procedures: Rationale, Technique and Outcomes.

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.

Acute Scrotum in an Infant with Kawasaki Disease

Kawasaki disease (KD) is a systemic vasculitis that occurs predominantly in infants and young children. The etiology of KD is unknown and coronary heart disease is a major complication of KD. Acute scrotum is a rare complication of acute KD, and not as well recognized as other manifestations of the disease. We report a 2-month-old boy with acute scrotum in the acute phase of KD. He was treated with intravenous immunoglobulin (total 2 g/kg) and aspirin (50 mg/kg/day). The treatment was effective in resolving his fever and other clinical symptoms, but 2 days after starting treatment he experienced scrotal swelling. Scrotal ultrasound and transillumination were used in the diagnosis of acute scrotum. After 2 months, a follow-up testicular ultrasound revealed a remission of the acute scrotum. Subsequently, he has been followed up for KD.

Extremely rare tumour--malignant mesothelioma of tunica vaginalis testis.

INTRODUCTION: Malignant mesothelioma of tunica vaginalis testis is an extremely rare tumour. It is often caused by exposition to asbestos, however, more often its occurrence is sporadic. The diagnosis is usually set secondarily during hydrocele surgery. This type of tumour should be considered in cases with with atypical hydrocele, especially haematocele or atypical shape of seminal covering. RESULTS: A case of an asbestos-exposed patient with described disease and long-term hydrocele is presented. The number of patients is so small that the guidelines are limited due to low statistical power (Fig. 2, Ref. 14).
