The detection of fetal anomalies has improved in the last years as a result of the generalization of ultrasound pregnancy screening exams. The presence of a cystic imaging in the fetal pelvis is a relatively common finding, which can correspond to a real congenital cystic lesion or result from the anomalous liquid accumulation in a whole pelvic organ, mainly the urinary bladder, the uterus, or the vagina. In selected cases with poor prognosis and/or inconclusive echographic findings, magnetic resonance may bring additional information in terms of the characterization, anatomical location, and real extension of the pathology...

REVIEW
Emre Huri, Mehmet Ezer, Eddie Chan
Laparoscopic surgery is routinely used to treat many urological conditions and it is the gold standard treatment option for many surgeries such as radical nephrectomy. Due to the difficulty of learning, laparoscopic training should start outside the operating room. Although it is a very different model of laparoscopic training; the aim of this review is to show the value of human cadaveric model for laparoscopic training and present our experience in this area. Fresh frozen cadaveric model in laparoscopic training, dry lab, cadaveric model, animal models and computer based simulators are the most commonly used models for laparoscopic training...

G Meermans, J Van Doorn, J-J Kats
AIMS: One goal of total hip arthroplasty is to restore normal hip anatomy. The aim of this study was to compare displacement of the centre of rotation (COR) using a standard reaming technique with a technique in which the acetabulum was reamed immediately peripherally and referenced off the rim. PATIENTS AND METHODS: In the first cohort the acetabulum was reamed to the floor followed by sequentially larger reamers. In the second cohort the acetabulum was only reamed peripherally, starting with a reamer the same size as the native femoral head...

BACKGROUND: The sacrococcygeal morphology of Arabs and Europeans has been studied using computed tomography (CT) or magnetic resonance imaging to determine the cause of coccydynia. Studies have suggested differences in sacrococcygeal morphology among ethnic groups. However, there are no data on the sacrococcygeal anatomy of Koreans. METHODS: We conducted a retrospective analysis of 606 pelvic CT scans that were taken at Cheju Halla General Hospital between 2008 and 2014...

BACKGROUND: Rectal prolapse is a disorder of the pelvic floor in which the layers of the rectal mucosa protrude outward through the anus. Surgical repair is the mainstay of treatment. Options include intra-abdominal procedures such as rectopexy and perineal procedures such as the Delorme and Altemeier perineal rectosigmoidectomy. Rectal and vaginal prolapse can often coexist. However, to our knowledge, there are no reported cases of rectal prolapse resolved by the repair of a compressive enterocele abutting the anterior rectal wall through a vaginal approach alone...

BACKGROUND: The two major perforators supplying the superficial circumflex iliac artery perforator (SCIP) flap are the medial (superficial) and lateral (deep) perforators but lacks detailed description. The purpose of this study was to clarify the anatomy. MATERIAL AND METHOD: In a prospective analysis of 142 patients, CT angiograms of 284 SCIP regions were evaluated and 142 SCIP flaps were surgically correlated. The origin of the SCIA, the origin of the medial perforator, the location where it penetrates the deep fascia, and its pattern of pathway after penetration of the superficial fascia were evaluated...

Rui Diogo, Peter Johnston, Julia L Molnar, Borja Esteve-Altava
Previous accounts of the origin of tetrapod limbs have postulated a relatively sudden change, after the split between extant lobe-finned fish and tetrapods, from a very simple fin phenotype with only two muscles to the highly complex tetrapod condition. The evolutionary changes that led to the muscular anatomy of tetrapod limbs have therefore remained relatively unexplored. We performed dissections, histological sections, and MRI scans of the closest living relatives of tetrapods: coelacanths and lungfish. Combined with previous comparative, developmental and paleontological information, our findings suggest that the characteristic tetrapod musculoskeletal limb phenotype was already present in the Silurian last common ancestor of extant sarcopterygians, with the exception of the autopod (hand/foot) structures, which have no clear correspondence with fish structures...

Due to the intricate relationship between the pelvic organs and vital structures, such as vessels and nerves, pelvic anatomy is often considered to be complex to comprehend. In oncological pelvic surgery, a trade-off has to be made between complete tumor resection and preserving function by preventing damage to the nerves. Damage to the autonomic nerves causes undesirable post-operative side-effects such as fecal and urinal incontinence, as well as sexual dysfunction in up to 80 percent of the cases. Since these autonomic nerves are not visible in pre-operative MRI scans or during surgery, avoiding nerve damage during such a surgical procedure becomes challenging...

INTRODUCTION: The wide use of laparoscopy for groin hernia repair has unveiled "hidden hernias" silently residing in this area. During the open repair of the presenting hernia, the surgeon was often unaware of these occult hernias. These patients postoperatively may present with unexplained chronic groin or pelvic pain. PRESENTATION OF CASE: Rare groin hernias are defined according to their anatomical position. Challenges in the diagnosis and management of occult rare groin hernias are discussed...

En bloc removal of the coccyx during sacrococcygeal teratoma resection is necessary to decrease the risk of recurrence. However, variable anatomy often makes the border between the coccyx and sacrum difficult to identify. We describe the use of intraoperative lateral pelvic X-ray to localize this border and ensure complete coccygectomy.

Pelvic injuries are not uncommon. The complex anatomy of the pelvic bones, the complex pattern of injuries, associated important structures such as neurovascular bundles, and difficult access make the reduction and fixation of these fractures difficult. Often the surgical outcomes are not satisfactory. Three-dimensional (3D) imaging using computed tomography (CT) scan (3DCT) has been the mainstay of preoperative evaluation since the 1980s, however, even with these images it may be difficult to understand complex injury patterns...

BACKGROUND: Sacral nerve stimulation is a common treatment for various pelvic floor disorders. It consists of the percutaneous introduction of electrodes through the posterior sacral foramina for therapeutic stimulation of the target sacral spinal nerve. The aim of our study was to determine the surface anatomical landmarks of the sacrum to facilitate identification of the posterior sacral foramina. METHODS: This study was conducted on 20 human cadavers. The cadavers were placed in a prone position, and all the soft tissues of the sacral region were removed to allow exposure of the osseous structures...

REVIEW
Satoru Kyo, Tomoyasu Kato, Kentaro Nakayama
Laparoscopic radical hysterectomy has been widely performed for patients with early-stage cervical cancer. The operative techniques for nerve-sparing to avoid bladder dysfunction have been established during the past three decades in abdominal radical hysterectomy, but how these techniques can be applied to laparoscopic surgery has not been fully discussed. Prolonged operation time or decreased radicality due to less accessibility via a limited number of trocars may be a disadvantage of the laparoscopic approach, but the magnified visual field in laparoscopy may enable fine manipulation, especially for preserving autonomic nerve tracts...

Acquired clitoral enlargement is a rare condition resulting from a variety of etiologies, including tumors and excess androgens. Few cases of nonmalignant schwannoma, a benign tumor of the peripheral nerve sheath, have been reported in the literature as causes of clitoral enlargement in patients without known neurofibromatosis. These painless, slow-growing tumors rarely recur once excised. We present the initial investigation of a patient with a large clitoral schwannoma and subsequent treatment with partial vulvectomy...

We present a case of a 76-year-old woman, who attended with features suggestive of renal colic; however on imaging, she was found to have a right pelvic kidney and a left-sided uretero-sciatic hernia (USH), identified on CT urography (CT urogram). She was managed conservatively as she had a normal renal function and reported no symptoms in follow-up appointments. USH are rare hernias, where the ureter herniates through the sciatic foramen. Patients might present with sepsis in which case they require emergency stenting either anterograde or retrograde or with pain in which a less urgent approach can be followed and plan for surgery...
