Review
Stress urinary incontinence is a common disease in middle-aged and elderly women, which seriously affects the physical and mental health of the patients. For this reason, researchers have carried out a large number of studies on stress urinary incontinence. At present, it is believed that the pathogenesis of the disease is mainly due to changes related to age, childbirth, obesity, constipation and other risk factors that induce changes in the urinary control anatomy, including the anatomical factors of the urethra itself, the anatomical factors around the urethra and the anatomical factors of the pelvic nerve. The combined actions of a variety of factors lead to the occurrence of stress urinary incontinence. This review aims to summarize the anatomical pathogenesis of stress urinary incontinence from the above three perspectives.

STUDY OBJECTIVE
To show how the evaluation for endometriosis can be included in the routine pelvic ultrasound examination.
DESIGN
Stepwise narrated video demonstration of the sonographic evaluation for endometriosis in routine pelvic ultrasound following the recommended sonographic approach published in the 2016 consensus paper by the International Deep Endometriosis Analysis (IDEA) group [1].
SETTING
Endometriosis is a common and often debilitating gynecological disorder that affects 5-10% of women [2]. The prevalence is even higher among women with symptoms of endometriosis [2], which include chronic pelvic pain, acquired dysmenorrhea, dyspareunia, dyschezia, menorrhagia, abnormal bleeding, and infertility. Approximately 80% of women who have endometriosis have superficial lesions, whereas 20% have deep infiltrating endometriosis (DIE; [3]). Laparoscopy is the gold standard for diagnosing endometriosis, because it allows the diagnosis of all forms of endometriosis and often immediate removal of superficial endometriosis. The removal of DIE is considerably more complicated and usually cannot be completed unless it was diagnosed preoperatively. The technique to diagnose DIE with transvaginal ultrasound (TVUS) was first described in detail in 2009 [4]. Since then, the accuracy of TVUS for the prediction of DIE has been well established in the literature [5-7]. TVUS is widely used as a first-line investigation for women with gynecological symptoms. The inclusion of an assessment for endometriosis in the routine pelvic ultrasound allows earlier diagnosis and better surgical outcomes for all women with DIE.
INTERVENTIONS
The evaluation for endometriosis in routine pelvic ultrasound based on the IDEA consensus promotes a 4-step dynamic ultrasound approach [1]: (1) routine evaluation of uterus and adnexa with particular attention for sonographic signs of adenomyosis and the presence or absence of endometriomas; (2) evaluation of transvaginal sonographic 'soft markers' such as site-specific tenderness and ovarian mobility; (3) assessment of status of pouch of Douglas using the real-time ultrasound-based "sliding sign;" and (4) assessment of DIE nodules in the anterior and posterior compartments, which involves assessment of the bladder, vaginal vault, uterosacral ligaments, and bowel, including rectum, rectosigmoid junction, and sigmoid colon. Because 5-10% of women with DIE also have ureteric endometriosis, it is useful to assess the kidneys. Silent hydronephrosis is easily identified in 50-60% of patients with ureteric involvement. Although it is possible to identify DIE involving the ureters more directly, this requires more advanced skills, and further studies are still needed to better define the accuracy of ureteric DIE detection by TVUS [8-10].
CONCLUSION
Traditionally, only pathologies of the uterus and ovaries are assessed during a routine pelvic ultrasound. Here we demonstrate that the routine ultrasound examination can easily be extended beyond the uterus and ovaries into the posterior and anterior pelvic compartments to evaluate structural mobility and to look for deep infiltrating endometriotic nodules, wherewith women suffering from DIE can benefit from a preoperative diagnosis and subsequently, a single, well-planned procedure in the hands of a well-prepared team.

Review
This review summarises the current reconstructive urological procedures seeking to optimise urinary tract function. This includes nephrectomy to avoid complications in non-functioning kidneys and reconstruction of uretero-pelvic junction stenosis. Re-implantation of the ureters is indicated in case of reflux or stenosis. The technique depends on the defect and ranges from re-implantation to transplantation of the kidney into the pelvis. Intestine is used for bladder augmentation or to create a new reservoir. Urethral reconstruction is used for complicated strictures, while penile reconstruction includes insertion of implants and straightening procedures.

Hand-assisted laparoscopic nephroureterectomy with cystoscopic en-bloc excision of the distal ureter and bladder cuff and isthmusectomy in a horseshoe kidney for invasive urothelial carcinoma of the renal pelvis.
Upper tract invasive urothelial carcinoma and horseshoe kidneys are familiar to the practicing urologist but relatively rare individual entities. The complication of managing them when they coexist in the same patient can be challenging. Herein, we present the first reported case in which an upper tract invasive urothelial carcinoma in a horseshoe kidney was successfully managed with a combined hand-assisted laparoscopic nephroureterectomy and isthmusectomy with cystoscopic en-bloc excision of the distal ureter and bladder cuff. This highlights the fact that complex anatomy can be managed in a completely minimally invasive fashion, and sound oncologic principles can still be maintained.

Review
Although most partial nephrectomies are performed as primary procedures in the elective or semi-imperative setting on kidneys with relatively normal anatomy, this is not always the case. The indications for partial nephrectomy continue to expand and it is becoming particularly relevant in patients with single functioning kidneys, poor kidney function, anatomical anomalies and hereditary syndromes predisposing to multiple kidney cancers, such as Von Hippel-Lindau syndrome. These, along with previous abdominal surgery, pose surgical challenges. In this article we offer advice as to how to tackle these unusual situations. An ability to master the whole range of indications will allow the modern upper renal tract surgeon to offer partial nephrectomy to a wider range of patients.

Review
OBJECTIVE
Provide an overview of sexual dysfunction in female urologic cancer patients, approaches for assessing sexual problems, and interventions to treat sexual dysfunction in this patient population.
METHODS
A review of the literature in urologic oncology was conducted. Research on other female pelvic cancers with similar treatments was also reviewed.
RESULTS
Sexual health is an important element of women's quality of life that is often not discussed and problems remain unaddressed. Urologic cancer treatments commonly result in sexual dysfunction (e.g., dyspareunia, vaginal dryness, problems with orgasm) in female patients, although more research is necessary to understand the impact of non-surgical treatments (e.g., radiation, chemotherapy, immunotherapy). As such, provider teams should complete necessary screening for sexual dysfunction during and after treatment. The 5 A's model (i.e., Ask, Advise, Assess, Assist, Arrange Follow-Up) provides a helpful guide for communicating about and addressing sexual health concerns with patients during the screening process. If it is determined that referral for further assessment and treatment of sexual dysfunction is needed, a number of non-pharmacologic (e.g., pelvic floor physical therapy; psychosexual counseling) and pharmacologic treatment approaches are available.
CONCLUSION
Sexual dysfunction is common in female urologic cancer survivors. Routine assessment and appropriate referral are essential for high quality patient care.

Lymphangiomatosis is a rare and benign mesenchymal disorder where there is developmental malformation and dilatation of lymphatic channels. The most common sites for lymphangiomatosis are the cervical neck and axilla, but it can also occur in the mediastinum, retroperitoneum, mesentery, omentum, colon, and pelvis. Renal lymphangiomatosis is an even rarer multicystic disorder which may be hilar, pericalyceal, paracalyceal, peripelvic, or para pelvic. We report a case of 24-year-old female with bilateral perirenal lymphangiomatosis. Her complain was bilateral flank pain and bilateral perinephric fluid collection with multiple sepatations was noted on radiological examination.

Review
The goal of functional renal imaging is to identify and quantitate irreversible renal damage and nephron loss, as well as potentially reversible hemodynamic changes. MR urography has evolved into a comprehensive evaluation of the urinary tract that combines anatomical imaging with functional evaluation in a single test without ionizing radiation. Quantitative functional MR imaging is based on dynamic contrast-enhanced MR acquisitions that provide progressive, visible enhancement of the renal parenchyma and urinary tract. The signal changes related to perfusion, concentration and excretion of the contrast agent can be evaluated using both quantitative and qualitative measures. Functional evaluation with MR has continued to improve as a result of significant technical advances allowing for faster image acquisition as well as the development of new tracer kinetic models of renal function. The most common indications for MR urography in children are the evaluation of congenital anomalies of the kidney and urinary tract including hydronephrosis and renal malformations, and the identification of ectopic ureters in children with incontinence. In this paper, we review the underlying acquisition schemes and techniques used to generate quantitative functional parameters including the differential renal function (DRF), asymmetry index, mean transit time (MTT), signal intensity versus time curves as well as the calculation of individual kidney glomerular filtration rate (GFR). Visual inspection and semi-quantitative assessment using the renal transit time (RTT) and calyceal transit times (CTT) are fundamental to accurate diagnosis and are used as a basis for the interpretation of the quantitative data. The importance of visual assessment of the images cannot be overstated when analyzing the quantitative measures of renal function.

A new method of removing calculi from the renal collecting system, in which the large and traumatic incision in the loin currently used is unnecessary, was attempted in 31 patients. Small dilators were introduced over a guide wire through a nephrostomy tube into the renal pelvis and a catheter inserted. The track was dilated in stages and two days later the nephrostomy tube was removed and a cystoscope introduced into the interior of the kidney. A stone basket was introduced down the operating channel of the cystoscope and maneuvered to secure the stone; the cystoscope, stone basket, and stone were then removed. The procedure failed in 11 of the 31 patients, in five because the needle could not be placed accurately initially and in six because the stone could not be removed despite the establishment of a nephrostomy track. In the remaining 20 patients the procedure was successful. This procedure is far less traumatic than the conventional operation. With the development of a flexible nephroscope and an ultrasonic stone disintegrator it will be possible also to remove larger stones and stones in the peripheral calices using this method.

AIM
To report the morphology of maternal kidneys captured on fetal magnetic resonance imaging (MRI) including kidney length, volume, renal pelvis diameter, and corticomedullary differentiation in pregnancy.
MATERIALS AND METHODS
A retrospective study of maternal kidney morphology captured incidentally on fetal MRI. Women without chronic kidney disease, with a complete view of both kidneys and a singleton pregnancy were included. Kidney length, maximal renal pelvis diameter, kidney volume, and corticomedullary differentiation ratio were measured independently in duplicate. Associations with maternal and pregnancy variables were explored using linear regression.
RESULTS
MRI images from 42 women were performed at 22-32 weeks' gestation. Serum creatinine concentrations are not checked routinely during pregnancy and were available for 15 (36%) women, with a median creatinine of 57 μmol/l (IQR: 50-63 μmol/l). Mean interpolar lengths were 10.9 and 10.4 cm for the left and right kidneys and varied with height. Mean maximal renal pelvis diameters were 9 mm and 12 mm, with upper reference intervals of 17 and 25 mm for the left and right kidneys, respectively. Renal volume in pregnancy was within the non-pregnant reference interval and varied with height and gestation.
CONCLUSIONS
Maternal kidney length and volume in pregnancy are within the normal reference intervals for non-pregnant women. Renal pelvis diameter in pregnancy measured using MRI is substantially higher than described previously by ultrasound, with implications for routine reporting.
