“…We previously reported this patient with bladder agenesis with anal atresia, left renal agenesis, left ovarian and renal tubular acidosis [5], Retrograde genitogram revealed a tortuously dilated right ureter without discernible renal calyces and a hypoplastic vagina. The left kidney was not found by ultrasonography or computed tomography.…”

“…A unicaly ceal kidney is a very rare anomaly in humans. Only 17 cases (21 kidneys) have been reported so far [1][2][3][4][5] and are often accompanied by other anomalies of the urogenital system as well as other organ systems. The renal function of the involved kidney is decreased in many cases [1], We report patients with unicalyceal kidneys which were asso ciated with other anomalies of the urinary tract.…”

“…Sunku et al described a 16-year-old female with secondary amenorrhea, synchronous cervical rhabdomyosarcoma, and Sertoli-Leydig cell tumor of the ovary with unilateral tuboovarian absence [37]. A number of cases noted pelvic masses diagnosed concomitantly with UOA with pathologies such as a mucinous cystadenocarcinoma, dermoid cysts, a serous cystadenoma, and fibrous calcified masses consistent with autoamputated ovary [34,[38][39][40][41][42][43][44][45][46].…”

Ovarian absence: a systematic literature review and case series report

Ovarian absence is an uncommon condition that most frequently presents unilaterally. Several etiologies for the condition have been proposed, including torsion, vascular accident, and embryological defect. A systematic review was conducted to describe the clinical presentation of ovarian absence, as well as its associations with other congenital anomalies, through a systematic search of Cochrane Library, ClinicalTrials.gov, Google Scholar, Ovid Embase, Ovid Medline, PubMed, Scopus, and Web of Science. Exclusion criteria included cases with suspicion for Differences of Sex Development, lack of surgically-confirmed ovarian absence, and karyotypes other than 46XX. Our search yielded 12,120 citations, of which 79 studies were included. 10 additional studies were found by citation chasing resulting in a total 113 cases including two unpublished cases presented in this review. Abdominal/pelvic pain (30%) and infertility/subfertility (19%) were the most frequent presentations. Ovarian abnormalities were not noted in 28% of cases with pre-operative ovarian imaging results. Approximately 17% of cases had concomitant uterine abnormalities, while 22% had renal abnormalities. Renal abnormalities were more likely in patients with uterine abnormalities (p < 0.005). Torsion or vascular etiology was the most frequently suspected etiology of ovarian absence (52%), followed by indeterminate (27%) and embryologic etiology (21%). Most cases of ovarian absence are likely attributable to torsion or vascular accidents, despite many references to the condition as “agenesis” in the literature. Imaging may fail to correctly diagnose ovarian absence, and diagnostic laparoscopy may be preferable in many cases as genitourinary anatomy and fertility considerations can be assessed during the procedure. Fertility is likely minimally or not affected in women with unilateral ovarian absence.

“…Metoki et al [ 7 ] classified bladder agenesis according to the site of ureter insertion into five types in females: (1) remnant cloacal type: persistent cloaca due to failure of the urorectal septum; hence, the ureters open into the remnant cloaca; (2) rectal type; (3) urogenital type: the ureter opening into the urethra or the vaginal vestibulum; (4) vaginal type; and (5) ectopic type: ureters open into the uterus.…”

Bladder Agenesis: A Systematic Review

Bladder agenesis is a rare congenital deformity characterized by the absence of the bladder. It is primarily observed in postmortem dissections of stillbirths rather than live births. The condition is often associated with other congenital anomalies, leading to the hypothesis that most affected fetuses do not survive to term. However, the exact cause and specific associated anomalies remain unclear and poorly described in the literature. The limited mention of bladder agenesis in textbooks and literature underscores the importance of creating a comprehensive source for future research in this field. Therefore, our objective is to collect and analyze data on bladder agenesis, focusing on associated anomalies and potential causes, to enhance our understanding of the condition. We conducted a thorough review of reports collected from three databases, Google Scholar, PubMed, and Science Direct, last searched on July 30, 2023, starting with 327 reports. Excluding duplicates and records written in languages other than English, veterinary studies, irrelevant reports, or stillbirths. Inclusion criteria were the following: cases must have proven bladder agenesis, not hypoplasia, and must have most of the information, including the age of diagnosis, presenting symptoms, gender, associated anomalies, and management or outcome of the patient. A quality assessment was conducted according to the Joanna Briggs Institute checklist for case reports. A total of 65 case reports from 56 articles were included in the review. Through our manual analysis, we documented a wild array of malformations associated with bladder agenesis. Among the reports reviewed, 93% exhibited urinary system malformations beside bladder agenesis, 77% were found to have reproductive malformations, 44% had gastrointestinal anomalies, 38% showed musculoskeletal malformations, 28% had cardiac malformations, and another 28% had vascular anomalies. The overall mortality rate was 38%, with a higher rate of 74% for males compared to 20% for females. By collating and analyzing those case reports, we aim to contribute to a better understanding of bladder agenesis and its associated anomalies, facilitating further investigations and advancements in the field.
