A Retrospective Analysis of Female Müllerian Duct Anomalies in Association With Congenital Renal Abnormalities

Müllerian Anomalies: Presentation, Diagnosis, and Counseling

Müllerian anomalies represent a complex collection of developmental defects occurring in up to 5% of the general population. They are increasingly more common in individuals with infertility (8.0%) and in those with a history of pregnancy loss (13.3%); they have the highest prevalence in individuals with a history of both (24.5%). A wide spectrum of anomalies can occur based on the stage at which müllerian development ceases in utero, ranging from mild (eg, a partial uterine septum) to severe, with complete absence of the cervix, uterus, and fallopian tubes (eg, müllerian agenesis). The components of the reproductive tract involved and, importantly, whether an obstruction of the tract is involved correlates with the timing of presentation, the constellation of associated symptoms, and the necessity for either medical or surgical management. Individuals, regardless of the severity of the defect, should be counseled on the gynecologic, reproductive, and obstetric risks associated with their specific müllerian anomaly to minimize adverse sequela and outcomes. We will review the clinical presentation, diagnostic evaluation, and clinical counseling of individuals with müllerian anomalies.

Unusual clinical presentations, pathogenesis and radiological review of Herlin-Werner-Wunderlich syndrome: A case report and literature review

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare anomaly of the female urogenital tract characterized by the combination of uterine didelphys, obstructed hemivagina, and ipsilateral renal anomalies. The exact incidence of the syndrome remains unknown, but it has been reported to be 1 per 2000 to 1 per 28,000 women. It is believed that the triad is a mesonephric duct-induced paramesonephric duct anomaly. In majority of the cases with complete hemivaginal obstruction, the pathology is diagnosed after menarche due to retained menstrual flow. While the common clinical presentations are dysmenorrhea, pelvic pain, intermenstrual bleeding, and pelvic mass, it can also manifest itself with unusual gastrointestinal and urinary tract symptoms. We present a case of HWW syndrome with gastrointestinal symptoms like worsening constipation and abdominal fullness. The unusual clinical presentation of this syndrome makes diagnosis more challenging. To solve such medical puzzles and prevent complications, detailed history-taking and radiological guidance are critical.

Renal agenesis: A meta-analysis of its prevalence and clinical characteristics based on 15 641 184 patients

Our objective was to analyse the newest relevant data on worldwide prevalence and associated symptoms of renal agenesis (RA). This meta-analysis builds on previous systematic reviews to include bilateral RA, its symptoms and data on gender, unilateral RA and anomaly location prevalence. Review of available data included records in English and other languages from PubMed, Embase, ScienceDirect, Web of Science, SciELO, BIOSIS, Current Content Connect Korean Journal Database and Russian Citation Index and Google. A total of 15 641 184 patients were analysed in relation to the prevalence of RA. The pooled prevalence of RA was 0.03% (95% CI: 0.03%-0.04%). Based on 500 subjects, a pooled prevalence of 47.96% (95% CI: 31.55%-64.58%) for unilateral and 52.04% (95% CI: 35.42%-68.45%) for bilateral RA has been set. Our study presents the newest generalized findings on bilateral RA. There appears to be universal disease and symptom prevalence with minor differences between world regions, although quality of future observational research should include genomic data. This will provide even further insight into the prognosis of various renal anomalies and their etiologies.

Endometrial Cancer in a Patient With Didelphys Uterus and a History of Renal Cancer: A Case Report and Literature Review

Müllerian duct anomalies (MDAs) concurrent with endometrial cancer are exceptionally rare, with only a few documented cases. Here, we present a case of endometrial cancer in both horns of a didelphys uterus in a 54-year-old woman with a history of renal cancer, who underwent left radical nephrectomy and left salpingo-oophorectomy. The patient sought medical evaluation due to postmenopausal vaginal bleeding. Hysteroscopy with dilation and curettage revealed the presence of two cervixes and two endometrial cavities, with pathology results indicating endometrioid adenocarcinoma (G1). Preoperative MRI staging confirmed the diagnosis of a double cervix and uterus. Subsequently, an open abdominal hysterectomy and a right salpingo-oophorectomy were performed, revealing a didelphys uterus (International Federation of Gynaecology and Obstetrics 2018, stage IA). This manuscript aims to explore the potential correlation between renal and endometrial malignancies in the presence of MDAs.

MRI presentations of Müllerian duct anomalies in association with unilateral renal agenesis

AIM

To evaluate the presentations of Müllerian duct anomalies (MDAs) associated with unilateral renal agenesis (URA) on magnetic resonance imaging (MRI).

MATERIALS AND METHODS

From 2014 to 2021, 92 patients with MDAs coexisting with URA who had undergone MRI were reviewed, and imaging patterns were analysed.

RESULTS

Based on the different imaging patterns, there were 74 cases of Herlyn-Werner-Wunderlich (HWW) syndrome (80.4%), nine cases of unicornuate uterus (10.9%), and nine cases of Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome (8.7%). In HWW syndrome, URA was ipsilateral to the vaginal or cervical obstruction. All the nine cases of unicornuate uterus were obstructive, and the most common subtype was unicornuate uterus with a non-communicating functioning rudimentary horn. The other two cases of unicornuate uterus with no rudimentary horn were obstructed due to cervical os obliteration, one of which was complicated with contralateral absent ovary. URA was contralateral to the unicornuate uterus in all cases. In MRKH syndrome, seven patients had bilateral rudiments and ovaries, all of which were unilaterally or bilaterally located above the pelvic brim, and URA was ipsilateral to the ectopic ovary in all cases. The other two patients had unilateral absent rudiment, ovary, and ipsilateral URA.

CONCLUSIONS

MRI presentations of URA-associated MDAs are diverse, with HWW syndrome being the most common form, followed by different patterns of unicornuate uterus and MRKH syndrome. An ectopic or absent ovary might be associated with URA in MRKH syndrome and unicornuate uterus.
