OBJECTIVE: To describe the clinical and imaging characteristics of Herlyn-Werner-Wunderlich syndrome (HWWS).
METHODS: This study presented an observational case series involving consecutive patients diagnosed with HWWS, whose medical records were retrospectively reviewed. From June 2012 to December 2022, there were a total of 85 patients with HWWS enrolled in our study. We obtained the medical history, including demographic characteristics, clinical presentation, treatment, complications, and radiologic examinations performed. Patients > 18 years of age (n = 58) were recontacted.
RESULTS: In our analysis, 27 patients were categorised as having complete obstruction, and 58 were categorised as having incomplete obstruction. The mean age at the onset of symptoms and diagnosis of complete obstruction was significantly younger than incomplete obstruction (P < 0.05). For complete obstruction, the median time between menarche and the onset of symptoms was 2.1 years, while for incomplete obstruction, it was 5.3 years. There was a significantly lower incidence of intermittent mucopurulent discharge, irregular vaginal haemorrhage, and occasional examination findings of complete obstruction than incomplete obstruction (P < 0.05). Complete obstruction was significantly associated with dysmenorrhea and pelvic endometriosis compared with incomplete obstruction (P < 0.05).
CONCLUSIONS: There are distinct clinical differences between patients with complete obstruction of the hemivagina and those with incomplete obstruction. HWWS can manifest as various combinations of uterine anomalies, communications anomalies, and renal anomalies. Early recognition and treatment can avoid complications and preserve fertility.
UNASSIGNED: Herlyn-Werner-Wunderlich syndrome (HWWS); complete obstruction; incomplete obstruction; obstructed hemivagina; congenital malformation.

Herlyn-Werner-Wunderlich syndrome is an uncommon urogenital anomaly defined by uterus didelphys, obstructed hemi-vagina and unilateral renal anomalies. The most common clinical presentation is dysmenorrhoea following menarche, but it can also present as pain and an abdominal mass. Prader-Willi syndrome is a rare neuroendocrine genetic syndrome. Hypothalamic dysfunction is common and pituitary hormone deficiencies including hypogonadism are prevalent. We report the case of a 33-year-old female with Prader-Willi syndrome who was referred to the Gynaecology clinic due to vaginal bleeding and abdominal pain. Abdominal ultrasound revealed a haematometra and haematocolpos and computed tomography showed a uterus malformation and a right uterine cavity occupation (hematometra) as well as right kidney agenesis. Vaginoscopy and hysteroscopy were performed under general anaesthesia, finding a right bulging vaginal septum and a normal left cervix and hemiuterus. Septotomy was performed with complete haematometrocolpos drainage. The association of the two syndromes remains unclear.

Herlyn-Werner-Wunderlich syndrome (HWWS), also known as OHVIRA syndrome (obstructed hemivagina and ipsilateral renal anomaly) is a complex congenital malformation characterized by a triad including uterine didelphys, hemivaginal obstruction, and ipsilateral renal agenesis. In this case report, we present a case of HWWS along with the challenges in diagnosis and multi-step treatment processes. A 25-year-old woman presented to Dr. Zainoel Abidin Hospital in Banda Aceh, Indonesia with a chief complaint of lower back pain for the past six months (two months after the marriage). The patient also complained of late menstruation, followed by thick yellow vaginal discharge resembling malodorous pus occurring after menstruation. Additionally, a history of fever and pain during intercourse was reported. Vaginal examination revealed purulent fluid emerging from a pinpoint hole on the right vaginal wall. Vaginal palpation revealed a two-branched uterus, along with a palpable cystic mass on the right vaginal wall. Ultrasound examination indicated the presence of the right and left hemi-uteri, measuring 4.7x1.35 cm and 5.7x1.26 cm in size, respectively with both ovaries appearing normal. Fluid accumulation was observed in the right hemivagina, while the left kidney exhibited normal features, and the right kidney showed signs of hypoplasia. The patient was diagnosed with uterus didelphys, fluid accumulation in the hemivagina, and right kidney hypoplasia. Magnetic resonance imaging (MRI) confirmed uterus didelphys and revealed narrowing of the right hemivagina, suggestive of HWWS. Hysteroscopy was performed to resect the vaginal septum with laparoscopic guidance, along with drainage of hematocolpos, pyocolpos and placement of an intracervical mold. Despite HWWs having conservative gradual management, it was opted to perform vaginal septum resection, hematocolpos and pyocolpos drainage and placement of an intracervical mould in this case, in order to relieve symptoms and restore the reproductive and sexual functions.

OBJECTIVE: To compare the anatomic variation between patients with a diagnosis of an obstructed hemivagina with an anorectal malformation (ARM) and those without an ARM.
METHODS: This was a retrospective chart review conducted at a single tertiary children\'s hospital. Patients with an obstructed hemivagina seen from 2004 to 2019 were included.
RESULTS: We identified a total of 9 patients diagnosed with an obstructed hemivagina: 4 patients with a history of ARM and 5 patients without an ARM. Patients presented with obstructive symptoms between the ages of 11 and 20. Two-thirds of patients had a left-sided obstruction. All patients without an ARM had ipsilateral congenital anomalies of the kidney and urinary tract. Half the patients with a history of ARM had an ipsilateral renal anomaly, and the other half had a contralateral renal anomaly.
CONCLUSIONS: Obstructed hemivagina occurs in patients with a history of ARM. However, unlike patients with isolated obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), patients with an ARM and an obstructed hemivagina can present with associated renal anomalies on either the ipsilateral or contralateral side. In our small case series, patients with a history of ARM had high septa and required more complex surgical management due to the inability to access the septum vaginally. Knowledge of renal anatomy and ureteral path is important because a hysterectomy may be needed to relieve the obstruction in patients with ARMs. A larger case series is needed to better characterize the spectrum of complex anomalies in patients with ARMs.

Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare developmental anomaly of the female reproductive system caused by a failure of fusion during Mullerian duct development. The triad of uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis characterizes HWWS. The most common presenting symptoms are dysmenorrhoea, pelvic pain, primary infertility in later years, and an abdominal mass due to hematometrocolpos.
UNASSIGNED: A 17-year-old girl presented to the authors\' department with recurrent low back pain, which was neither responsive to analgesics nor associated with urinary complaints, vomiting, or fever. Imaging techniques confirmed she had the triad of uterus didelphys, obstructed hemivagina, and right renal agenesis.
UNASSIGNED: The genital system is the same for males and females before 6 weeks of pregnancy. HWWS is a rare congenital disorder as a result of the failure of fusion during Mullerian duct development. It consists of a didelphic uterus, hemivaginal septum, and unilateral renal agenesis.
UNASSIGNED: Shame and social stigma associated with virginity continue to endanger the lives of many girls in Syria. To complicate matters further, the low resources in Syria produced by war pose a difficult challenge in managing many gynecological conditions, including HWWS, like this case, in which endoscopic technologies were not available, necessitating open surgery while keeping in mind preserving hymen intactness. So, the authors indicate that preserving virginity could be conducted even though the approach is open surgery by very careful intervention and experienced surgeons.

To demonstrate vaginoscopic resection of the oblique vaginal septum in a girl with Obstructed Hemi Vagina and Ipsilateral Renal Agenesis (OHVIRA) syndrome before menarche.
Stepwise demonstration of surgical technique with narrated video footage.
OHVIRA syndrome is a rare urogenital anomaly in which patients present after menarche, with progressive dysmenorrhea and a palpable pelvic mass due to hematocolpos and hematometra on the obstructed side. Delay in diagnosis may cause endometriosis, pelvic adhesions, and infertility [1,2]. A 12-year-old, premenarchal girl with complaints of pelvic pain and an ultrasound report of right renal agenesis was referred to the urology department of our hospital. She was also found to have uterus didelphys and a loculated fluid collection behind the urinary bladder on ultrasonography and on magnetic resonance imaging (Figs. 1 and 2). A probable diagnosis of OHVIRA syndrome with mucocolpos was made [3].
Vaginoscopy showed an obstructing bulging vaginal septum on the right side. The left uterine horn was inspected by hysteroscopy. The vaginal septum was incised vaginoscopically with monopolar cautery using Collins knife (Video still 1) [4-6]. The collected mucus was drained. The right cervix and the right uterine horn were visualized by hysteroscopy. Edges of the septum were resected with a resectoscope loop (Video still 2). The hymen was not injured during the surgery. Relook vaginoscopy done after 2 months showed a normal and healed vagina.
Vaginoscopic resection of the obstructing oblique vaginal septum in OHVIRA syndrome is a very simple, minimally invasive, and virginity conserving surgery. Early diagnosis and treatment can prevent future complications due to cryptomenorrhea.

To show a conservative surgical treatment for a female adolescent affected by Wunderlich syndrome with didelphys uterus and obstructed hemivagina.
Stepwise demonstration of the technique with narrated video footage.
In the context of obstructive congenital müllerian anomalies, involving a stagnation of menstrual blood, the Wunderlich syndrome is the most common and constantly characterized by the duplicity of the uterine body, by the presence of an imperforate hemivagina, and by renal agenesis ipsilateral to the obstructed hemivagina. The imperforate hemivagina leads to dysmenorrhea and abdominal pain, owing to the hematocolpos and the hematometra, which arose immediately after the menarche. This is the case of a 14-year-old female adolescent affected by Wunderlich syndrome referred to the San Raffaele Hospital adolescent center (Milan, Italy) for dysmenorrhea and abdominal pain. At vaginal exploration, a right imperforated hemivagina and hematocolpos were highlighted. A diagnostic magnetic resonance imaging (MRI) found the duplicity of the uterine body, the hematometra, and the right renal agenesis.
A combination of explorative laparoscopy and surgical vaginal time leads to the excision of the vaginal septum that allows the drainage of the hematocolpos and of the hematometra. Three surgical steps are described: 1. First laparoscopic step: exploration of the abdominal cavity with the detection of a double uterine body, an enlarged hemiuterus, and an enlarged hemivagina caused by the hematometra and the hematocolpos. Careful evaluation of adnexa for eventual presence of hematosalpinx. 2. Vaginal step divided into the following: (A) puncture of the vaginal tumescence (corresponding to the imperforated hemivagina) with a 19-gauge needle mounted on a syringe. Aspiration results in thick creamy black material (old menstrual blood). (B) In correspondence with the needle puncture, a full-thickness incision of the vaginal wall widely opening the second uterine cervix and (C) stabilization of the opening by the marsupialization of the edge of the obstructed hemivagina were performed. 3. Second laparoscopic step: having emptied the hematocolpos of the left hemiuterus, the didelphys uterus and the disappearance of the hematocolpos can be clearly seen.
Here, we demonstrate a conservative surgical approach for the treatment of Wunderlich syndrome. This rare malformation is characterized by an extreme variability of the anatomic presentation, and the precise identification of the variety together with the early diagnosis is of fundamental importance for the surgical correction.

BACKGROUND: OHVIRA (Obstructed Hemivagina and Ipsilateral Renal Anomaly or Herlyn-Werner-Wunderlich syndrome) is a rare Müllerian malformation. Usually, symptoms begin with worsening dysmenorrhea in post-menarche adolescents. The management in pre-menarche period is controversial and has only recently been subject of study.
OBJECTIVE: To review the experience of a pediatric tertiary center and to propose an age-specific management protocol for patients diagnosed before menarche.
METHODS: A retrospective cohort study (review of medical records - period 2009-2021).
RESULTS: Twenty-eight patients were diagnosed (mean age 11.9 years), seven (25%) before menarche, one (3%) perinatally. One patient had Floating-Harbor syndrome. Twenty-three patients had ipsilateral renal agenesis, while five had a multicystic-dysplastic kidney. The contralateral kidney showed hypertrophy in 25 patients, pelvicalyceal ectasia in 8 and dysplasia in 1. Twenty-four patients were symptomatic. Three of the seven diagnosed prior to menarche had symptoms. All post-menarche diagnosed patients were symptomatic. Twenty-six patients underwent surgery (one-stage drainage, vaginal septal resection, and vaginoplasty). Asymptomatic pre-menarche patients were followed-up until surgery after menarche onset. No patient underwent surgery prior to menarche solely for OHVIRA diagnosis. At follow-up (median 3.5 years, 3 lost to follow-up), eighteen patients were asymptomatic, one developed endometriosis, one had impaired renal function, two needed reoperations.
CONCLUSIONS: Pre-menarche OHVIRA patients, without symptoms, should undergo regular follow-up until the onset of menarche. Surgery must be considered in post-menarche or symptomatic patients. Post-operative, long-term follow-up is required, evaluating both renal and gynecological issues.
METHODS: IV.

BACKGROUND: Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare female urogenital tract malformation.
OBJECTIVE: To present 10 patients with OHVIRA treated at the clinical center. To perform a systematic review of OHVIRA case series related to the prevalence of anatomical variants, surgical interventions and endometriosis, and to compare them with our case series.
METHODS: Medical records from 10 OHVIRA patients treated between 2016 and 2020 were retrospectively reviewed. For the systematic review, PubMed and Web of Science were used to search for relevant studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were strictly followed.
RESULTS: The most common anatomical variant includes left obstructed hemivagina (50.7%) with isolated hematocolpos or hydrocolpos (55.9%), uterus didelphys (82.9%), and ipsilateral renal agenesis (92.2%). Vaginal septectomy was the most common surgical approach (86.5%). Hemivaginectomy (2.2%), hemihysterectomy (4.2%), or total hysterectomy (0.7%) were also performed in several patients. Some subjects required salpingectomy (3.3%) or oophorectomy (1.8%). 7.5% of patients, mainly infants, did not require surgery due to the spontaneous resolution of hydrocolpos. Endometriosis was fortuitously found in 13.6% of the selected cases who underwent laparoscopy or laparotomy.
CONCLUSIONS: The most common variant of OHVIRA includes isolated hematocolpos and a thick vaginal septum between adjacent hemivaginas. Endometriosis was present in approximately 14% of OHVIRA patients, but this number is probably underestimated. Routine laparoscopy is not required. However, all patients need further monitoring due to a higher risk of endometriosis. Based on the analyzed studies and our case series, vaginal septectomy is a sufficient surgical technique to relieve symptoms and prevent possible complications in most OHVIRA patients.

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital anomaly of Mullerian duct development characterized by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. We present a case of a 29-year-old nulliparous woman, who was referred to our hospital complaining of chronic pelvic pain, dyspareunia, and a palpable mass in her vagina. At the age of 12, she underwent surgery because of a didelphys uterus diagnosis. Subsequently, she was operated on twice for endometriomas. At our institution, clinical and imaging findings revealed an obstructed hemivagina setting the diagnosis of HWW syndrome. Some of the various syndrome types may go unnoticed for months or even years after the onset of menstruation. Early diagnosis, followed by proper surgical treatment, is the key to avoid potentially severe complications.
