BACKGROUND: Congenital inguinal hernia, hydrocele and undescended testis (UDT) are associated with patent processus vaginalis. The smooth muscles present in the processus vaginalis aid in the descent of the testis and undergo programmed cell death after testicular descent leading to obliteration. The persisting amount of smooth muscle in the processus vaginalis influences the clinical outcome as inguinal hernia, hydrocele or UDT. Therefore, a study was conducted to evaluate the processus vaginalis in these three conditions to observe the presence and phenotype of smooth muscle cells and the presence of myofibroblasts.
METHODS: The processus vaginalis sacs in patients with inguinal hernia, hydrocele and UDT were examined using light microscopy for the presence and distribution of smooth muscle cells and immunohistochemical staining for vimentin, desmin, and α-smooth muscle actin (SMA) to identify the smooth muscle phenotype. Transmission electron microscopy was also performed in all the sacs to observe the presence of myofibroblasts.
RESULTS: Seventy-eight specimens of processus vaginalis (from seventy-four patients), distributed as 47%, 27%, and 26% as inguinal hernia, hydrocele and UDT respectively, were included in the study. The sacs from inguinal hernia and hydrocele had significantly more presence of smooth muscles distributed as multiple smooth muscle bundles (p < 0.001). Desmin and SMA staining of smooth muscle cells was observed in significantly more sacs from hydrocele, followed by inguinal hernia and UDT (p < 0.001). The sacs from UDT had a significant presence of striated muscles (p = 0.028). The sacs from inguinal hernia had a significant presence of myofibroblasts, followed by hydrocele and UDT (p < 0.001) and this significantly correlated with the light microscopy and immunohistochemical features. The processus vaginalis sacs from four female patients did not differ statistically from the male inguinal hernia sacs in any of the above parameters.
CONCLUSIONS: The processus vaginalis sacs in pediatric inguinal hernia, hydrocele and undescended testis differ in the presence, distribution and phenotype of smooth muscles and the presence of myofibroblasts. The clinical presentations in these entities reflect these differences.

Background and Objectives: Scrotal swelling or hydrocele is a rare complication of acute pancreatitis described in the literature. We present a case of penoscrotal swelling caused by the first attack of acute interstitial edematous alcohol-induced pancreatitis in a young male patient. Case report: A 22-year-old man was admitted to the emergency unit due to diarrhea and vomiting since morning which was followed by severe abdominal pain. Urgent abdominal multislice CT scan showed steatosis, pancreatic swelling and acute peripancreatic fluid collection (interstitial edematous pancreatitis). Also, scan showed fluid between small bowel loops and along the anterior renal fascia, while there was minimal amount of fluid in the Douglas space. There was no sign of penoscrotal swelling. On the second day of admission, the patient developed left scrotal swelling and mild pain without erythema. On the fourth day, a control CT scan showed progression to moderately severe pancreatitis (CT severity index 4). Dilated scrotal veins of the pampiniform venous plexus with an increased caliber of the testicular veins were present on both sides, from the scrotum to the level of the inguinal canal. Penoscrotal swelling was significantly reduced on discharge. Conclusions: Penoscrotal swelling is a rare complication or manifestation of acute inflammation of the pancreas. It is important to identify scrotal swelling caused by pancreatitis because in severe cases it can be related to possible infertility in the future.

The hydrocele is overall a rare condition in urology. A differentiation between primary and secondary hydrocele is essential for further treatment. A primary hydrocele with a patent vaginal process tends to spontaneously regress in the first 2 years of life in newborns. If treatment is necessary, open as well as laparoscopic methods are available with good results. The treatment of scrotal pathologies, especially secondary hydrocele, often poses a challenge in the clinical practice. Despite the benign nature, supposedly simple surgical techniques and good chances of healing, postoperative complications are frequent. In comparison to open surgery, sclerotherapy provides a good alternative for the treatment of secondary hydrocele.
UNASSIGNED: Die Hydrozele ist insgesamt ein seltenes Krankheitsbild in der Urologie. Die Unterscheidung zwischen einer primären und einer sekundären Hydrozele ist unerlässlich für die weitere Therapie. Die primäre Hydrozele mit dem offenem Processus vaginalis neigt im Neugeborenenalter zur spontanen Rückbildung in den ersten beiden Lebensjahren. Sollte eine Behandlung notwendig sein, stehen offene sowie laparoskopische Methoden mit guten Ergebnissen zur Verfügung. Die Behandlung von skrotalen Pathologien insbesondere der sekundären Hydrozele stellt im klinischen Alltag häufig eine Herausforderung dar. Trotz der Benignität, vermeintlich einfacher Operationstechnik und guter Heilungschancen sind postoperative Komplikationen häufig. Zur offenen Operation bietet die Sklerosierungstherapie eine gute Alternative zur Behandlung der sekundären Hydrozele.

BACKGROUND: Although the laparoscopic approach become standard for the treatment of many surgical conditions many studies still debating whether laparoscopic surgery has significant advantages over open surgery in regards to hernia or hydrocele treatment. This study aimed to evaluate the outcomes of treatment of treatment of communicating hydrocele in pediatric patients between laparoscopic percutaneous internal ring suturing (PIRS) and open ligation of the patent processus vaginalis (PPV).
METHODS: The medical records of pediatric patients who underwent surgery for communicating hydrocele between 1 January 2019 and 1 January 2024 were retrospectively reviewed. The primary objective of the study is to investigate the outcomes of treatment (complications and recurrence rates) of communicating hydrocele in children between laparoscopic and open surgical approaches. Secondary outcomes of the study are the duration of surgery and anesthesia, length of hospital stay (LOS), frequency of hospital readmissions (ReAd) and unplanned return to the operating room (uROR).
RESULTS: A total of 198 children underwent surgery for a communicating hydrocele (205 repairs, as 7 cases were bilateral) and were included in the study. Of these, 87 children underwent a PIRS, while the remaining 111 cases underwent open ligation of the PPV. No recurrence of the hydrocele was observed in any of the study groups. Intraoperative complication (epigastric vein injury) was noted in two cases in both groups (2.3% vs. 1.8%, p > 0.999). A slightly higher number of postoperative complications was observed in the open group (n = 7, 6.3%) compared to the PIRS group (n = 2, 2.3%) (p = 0.190). The median duration of surgery (15 min (IQR 10, 17) vs. 21 min (IQR 15, 25); p < 0.001) and anesthesia (30 min (IQR 25, 40) vs. 40 min (IQR 35, 40); p < 0.001) were significantly lower in the PIRS group compared to open ligation of the PPV. In addition, a significantly shorter median of LOS was observed in the PIRS group compared to the open PPV group (9 h (IQR 8, 12) vs. 24 h (IQR 12, 24; p < 0.001). No cases of ReAd and uROR were observed in any of the study groups.
CONCLUSIONS: PIRS is a safe and effective laparoscopic technique that can be used in the treatment of communicating hydrocele in children. PIRS showed excellent outcomes and a low incidence of complications and recurrences, comparable to traditional open surgery.

OBJECTIVE: We present an overview of the 2024 updates for the European Association of Urology (EAU)/European Society for Paediatric Urology (ESPU) guidelines on paediatric urology to offer evidence-based standards for perioperative management, minimally invasive surgery (MIS), hydrocele, congenital lower urinary tract obstruction (CLUTO), trauma/emergencies, and fertility preservation.
METHODS: A broad literature search was performed for each condition. Recommendations were developed and rated as strong or weak on the basis of the quality of the evidence, the benefit/harm ratio, and potential patient preferences.
UNASSIGNED: Recommendations for perioperative management include points related to fasting, premedication, antibiotic prophylaxis, pain control, and thromboprophylaxis in patients requiring general anaesthesia. MIS use is increasing in paediatric urology, with no major differences observed among different MIS approaches. For hydrocele, observation is the initial approach recommended. For persistent cases, treatment varies according to the type of hydrocele. CLUTO cases should be managed in tertiary centres with multidisciplinary expertise in prenatal and postnatal management. Neonatal valve ablation remains the mainstay of treatment, but associated bladder dysfunction requires continuous treatment. Among urological traumas and emergencies, renal trauma is still an important cause of morbidity and mortality. Conservative management has become the standard approach in haemodynamically stable children. Ischaemic priapism is a medical emergency and requires stepwise management. Initial management of nonischaemic priapism is conservative. Fertility preservation in prepubertal children and adolescents has become an increasingly relevant issue owing to the ever-increasing number of cancer survivors receiving gonadotoxic therapies. A major limitation is the scarcity of relevant literature.
CONCLUSIONS: This summary of the 2024 EAU/ESPU guidelines provides updated guidance for evidence-based management of some paediatric urological conditions.
RESULTS: We provide a summary of the updated European Association of Urology/European Society for Paediatric Urology guidelines on paediatric urology. There are recommendations on steps to take before and immediately after surgery, management of hydrocele, congenital lower urinary tract obstruction, and urological trauma/emergencies, as well as preservation of fertility. Recommendations are based on a comprehensive review of recent studies.

UNASSIGNED: Encysted spermatic cord hydrocele is a rare anomaly characterized by obstruction of processus vaginalis closure. Clinically, it presents as a swelling in the inguinal region extending to the upper scrotum and does not communicate with the peritoneal cavity. It is often mistaken for indirect inguinal hernias, inguinal lymphadenopathy, undescended testis, and primary tumors of the cord in infants and children, making the diagnosis challenging.
METHODS: We report the cases of five male patients aged nine months to 12 years who presented with painless swelling on the right side of the scrotal region. Physical examination revealed firm masses in the right inguinal region with positive transillumination, negative cough impulse tests, and irreducibility. Inguinal and scrotal ultrasonography showed an anechoic cystic lesion with thin walls, without any signs suggestive of a hernia. Patients were diagnosed with encysted spermatic cord hydrocele and advised to undergo cyst excision. The postoperative periods were uneventful, and expected recovery was observed at one-week and one-month follow-ups.
UNASSIGNED: Encysted spermatic cord hydroceles are rare causes of painless inguinal swelling. The medical history and clinical findings can be used to establish a diagnosis, which can be confirmed using ultrasonography. Management depends on differentiating between spermatic cord hydrocele and scrotal hydrocele and involves considering the type. Treatment options range from conservative measures to surgery, particularly for non-communicating hydroceles that persist beyond 12-18 months or enlarge in size.
CONCLUSIONS: Encysted hydrocele of the cord is rare and is often mistaken for indirect inguinal hernias in infants and children. This similarity makes the diagnosis challenging and necessitates vigilance from clinicians. Surgical intervention results in optimal outcomes, especially in cases where the hydrocele persists beyond 12-18 months or with size progression.

Hydrocele is a common benign scrotal condition affecting adult men. The gold standard of treatment includes hydrocelectomy, with the use of Winkelman\'s/Jaboulay\'s technique or Lord\'s procedure. The vessel-sealing device (VSD) is a blood vessel-sealing system, known to enhance patient\'s postoperative outcomes in multiple different surgeries. The aim of this study was to compare the procedural and postoperative outcomes of a novel hydrocelectomy method using a VSD to the conventional hydrocelectomy using the Jaboulay\'s technique. We performed A retrospective review for all adult cases who underwent surgical hydrocelectomy at Hillel Yaffe Medical Center between 2011 and 2022. Study cases were grouped into one of two groups, patients undergoing conventional hydrocelectomy, or patients undergoing hydrocelectomy with the use of a VSD. Patients operated using other techniques were excluded. Data collected included demographic data and operative and postoperative parameters. Among 102 patients, 47 underwent Jaboulay\'s technique and 55 underwent hydrocelectomy using a VSD. We observed significantly shorter duration of hospitalization (1.18 vs 1.53, P = 0.038) and shorter surgery time (31.87 vs 37.4, P = 0.003) when using the VSD during a hydrocelectomy compared to conventional surgical hydrocelectomy. Both techniques indicated low complication rates and no recurrent hydrocele was observed in either group. We report our experience with a novel surgical technique that includes hydrocelectomy with the use of VSD. Our findings demonstrated shorter surgery time and length of hospitalizations, which may indicate improved patient\'s postoperative outcomes with the use of the VSD for hydrocelectomy.

While hydrocelectomy is the gold-standard for treating hydroceles, it poses an increased risk to patients and a greater burden to the healthcare system. Sclerotherapy is an alternative treatment for hydroceles that involves injecting a sclerosant into the hydrocele under ultrasound guidance. This literature review aimed to assess the types of sclerosants used and how sclerotherapy compares to hydrocelectomy. A literature search was conducted of MEDLINE and EMBASE using the terms \"sclerotherapy\" and \"hydrocelectomy,\" which yielded 1058 studies, of which 29 met the inclusion criteria. Only studies published after 2000 were included to ensure the most recent information was reviewed. The results showed hydrocele sclerotherapy is done using a variety of sclerosants. The most used agents are polidocanol, phenol, and STS. Of these, phenol had the highest clinical success rate of 96.5%. There was evidence for the use of atypical agents, such as tetracycline antibiotics, which yielded cure rates up to 93%, and alcohol, which was found to be especially useful for treating multiseptated hydroceles. The results comparing sclerotherapy to hydrocelectomy indicated hydrocelectomy to be a more effective method in completely curing hydroceles. However, this came at the cost of more complications. Additionally, sclerotherapy was found to be more advantageous for secondary outcomes, such as healthcare costs and burden to patients. In conclusion, this review shows that while hydrocelectomy is more effective, sclerotherapy is a valuable alternative for treating hydroceles. Due to the lack of standardization among studies, a definitive conclusion cannot be made regarding which sclerosant is best to use.

Hydrocele of the canal of Nuck is a rare condition which is commonly misdiagnosed as an inguinal hernia due to the unfamiliarity of clinicians with this pathology. There are three different types of hydrocele of the canal of Nuck, with type 1 being the most common, typically presenting as a unilocular cystic lesion with no communication with the peritoneal cavity. We present a case of a two-month-old female patient with an enlarging inguinal swelling raising the suspicion for an inguinal hernia or lymphadenopathy, with sonographic imaging revealing a fluid collection in the canal of Nuck, suggestive of a hydrocele. Diagnostic radiology plays a crucial role in the initial diagnosis of a canal of Nuck hydrocele, and ultrasound is considered the modality of choice for early diagnosis differentiating it from other causes of inguinal swelling.

Testicular and scrotal abnormalities can occur in children, adolescents, and adults. The lesions, often accompanied by pain and swelling/enlargement of the scrotum, can cause anxiety in patients and their parents. Regardless of age, proper diagnosis is based on adequate anamnesis and physical examination. Color Doppler ultrasound is the first-line test in the differential process of testicular and scrotal diseases. Testicular and scrotal lesions require differentiation for benign and malignant processes as well as therapeutic management, including urgent surgical intervention. The aim of this paper is to present the most common causes of testicular and scrotal abnormalities in pediatric and adult patients and to outline the symptoms and diagnostic and therapeutic management.
