A Case Study of Urinary Tract Infection and its Ayurveda Management

A Urinary Tract Infection (UTI) is the most common bacterial infection encountered in daily medical practice. It is more prevalent in females than males due to the shorter urethra in females, which allows bacteria a quicker access to the bladder. One in five women develop UTI at least once in her lifetime. UTIs in men are uncommon, but when they do occur, they can be very serious. In Ayurveda, the symptoms of UTI closely resemble a condition known as Mutrakriccha. Acharya Charaka has explained eight types of Mutrakriccha in Charaka Chikitsa Sthana 26. In this condition, the aggravated Pitta Dosha, along with Apana Vayu, reaches the Vasti (bladder) and affects the Mutravaha Srotas, leading to painful and burning urination. In this case report, a 50-year-old male patient presented with symptoms of urinary urgency, increased frequency, and intermittent burning urination for the past 1-2 months. He was diagnosed with UTI and was effectively managed with Syp. Neeri, Chandraprabha Vati, Gokshuradi Guggulu, Shweta Parpati, and Hajaralyahud Bhasma. The treatment resulted in significant improvement in signs, symptoms, and urine examination results. During follow-up visits, there were no recurrences of UTI. Ayurvedic management offers a promising alternative for treating Mutrakriccha.

Relationship between the Presence of Human Papillomavirus in the Female Urethra and Recurrent Urinary Tract Infections.

Introduction: Recurrent urinary tract infections (rUTIs) are highly prevalent health issues among women, significantly impacting their quality of life. Urethral pain or urethritis can arise from infectious or non-infectious origins. The presence of Human Papillomavirus (HPV) in the urogenital tract has been associated with high-risk sexual behaviors, but its presence in the female urethra without such behaviors has not been thoroughly investigated. Objectives: The study aims to determine the presence of HPV in the urethra of women with recurrent urinary tract infections (rUTIs) and concomitant urethral syndrome and to compare the clinical and microbiological characteristics of women with and without urethral HPV, specifically focusing on those without high-risk sexual behaviors. Methods: This prospective multicenter study included 138 women over 18 years old with rUTIs and concomitant urethral pain syndrome. High-risk sexual behaviors, sexually transmitted infections, and vaginitis were set as exclusion criteria. Participants were divided into two groups: NHPV (n = 72) with no urethral HPV and HPV (n = 66) with urethral HPV presence. Variables analyzed included age, body mass index (BMI), follow-up duration, comorbidities, treatments, toxic habits, surgical history, main symptoms, urine sediment findings, and cultures from urine and vaginal exudate. HPV genotyping was also performed. Descriptive statistics were used, along with Student's t-test, Chi-square, Fisher's exact test, ANOVA, and multivariate cluster analysis. Results: The NHPV group was older on average (48.75 years) compared to the HPV group (39.09 years). The HPV group had a longer follow-up period (2634 days vs. 1975 days in NHPV). Urinary incontinence was significantly more common in NHPV (63.89%) compared to HPV (18.18%) (p = 0.001). HPV-positive women had a higher prevalence of verrucous lesions in the vaginal introitus (64% vs. 8% in NHPV). Additionally, the HPV group showed higher rates of pyuria (27.27%), vaginal Candida albicans (36.26%), and positive urine cultures for Escherichia coli (47.83%), Enterococcus faecalis (36.36%), and Klebsiella pneumoniae (21.74%). No significant differences were observed between the groups concerning BMI, smoking habits, diabetes, or the main symptom at consultation. The most common HPV genotypes identified were G35, G42, and G66 (each 27%). Multivariate analysis revealed that sensitivity to nitrofurantoin was the most significant variable in the HPV group (importance of 0.96), followed by fosfomycin (0.79), trimethoprim (0.79), and amoxicillin (0.71). Conclusions: HPV was present in the urethra of 47.8% of women with rUTIs and concomitant urethral syndrome who did not exhibit high-risk sexual behaviors. These women were younger and had a longer duration of symptoms compared to those without urethral HPV. The identification of Enterococcus faecalis, Escherichia coli, and Klebsiella pneumoniae was more common in the HPV group. The sensitivity of bacteria to nitrofurantoin and fosfomycin is crucial for the clinical management of these patients. The presence of urethral HPV should be considered in the evaluation and treatment of women with rUTIs and urethral syndrome.

Characterization of urethra closure in female neonatal mice at histological and molecular levels.

Female hypospadias is a little-known and poorly studied birth defect. This research establishes an anatomical and molecular foundation for future research to investigate the origins of this defect. Hypospadias is a congenital anomaly of the external genitalia where the urethra does not properly close. In humans, hypospadias is mostly reported in male newborns, whereas in females hypospadias is rare, although it is generally considered to be under-reported. Improper urethra closure in the female genitalia can cause recurrent genitourinary tract infections and infertility. In mice, female hypospadias was induced by exposure to exogenous estrogenic compounds. Aside from the link between estrogen exposure and female hypospadias, the process of female urethra closure is largely unstudied, with the precise timing of urethra closure and associated molecular mechanisms remaining poorly understood. To address this gap, we determined when urethra closure occurs and identified gene expression patterns during the process of urethra closure in female neonatal mice from postnatal day (PND) 5 to 10. Using whole mount imaging and histology, we discovered that the initiation of urethra closure begins at PND7, and urethra closure is fully completed by PND10. To identify the genes associated with urethra closure, we conducted bulk RNA sequencing on female external genitalia prior to and after urethra closure. Gene ontology analyses revealed an increase in steroidogenic gene expression (Star, Hsd3b6, and Cyp17a1) during urethra closure, suggesting that the female genitalia locally produce steroids which could facilitate steroid signaling within the genitalia. With this study, we establish an anatomical timeline of female urethra closure and hypothesize a paracrine steroid signaling mechanism of urethra closure. These observations provide entry points to aid in further understanding external genital abnormalities, like hypospadias, in females.

A case report of urethral prolapse in young girls: Clinical manifestations and surgical management

Background and importanceUrethral Prolapse (UP), first described by Solinger in 1732, is a rare condition characterized by the circular protrusion of the distal urethral mucosa through the external meatus, forming a hemorrhagic, sensitive vulvar mass. This condition is most commonly observed in prepubertal black females. This case report details the clinical manifestations and surgical management of UP in three young girls. Cases presentationThree girls, aged 4, 5, and 6 years, were admitted with symptoms of vaginal blood spotting. Physical examinations revealed moderate bleeding and a red ring of congested, edematous tissue prolapsing through the urethral meatus. Diagnostic procedures confirmed UP, and surgical management was undertaken. The surgical approach involved the complete excision of the prolapsed tissue and mucosal-to-mucosal anastomosis under general anaesthesia. Postoperative follow-up over a mean period of 11 years showed no recurrence or urethral stricture. Clinical discussionUP is a rare benign condition primarily affecting the female urethra, with several hypothesized etiologies, including weak pelvic floor structures and increased intraabdominal pressure. The typical presentation includes vaginal bleeding and a doughnut-shaped mass around the urethral meatus. Conservative management may be considered for mild cases, but surgical excision is recommended for severe cases, offering a safe and effective solution with low recurrence rates. ConclusionsUP in children, although rare, should be considered in cases of unexplained vaginal bleeding. Diagnosis is primarily clinical, and surgical resection provides a definitive and cost-effective treatment.

Distribution of prostatic markers in glands of the female urethra and anterior vaginal wall-a rapid autopsy study.

There are varying reports of immunohistochemically detected prostatic marker protein distribution in glands associated with the female urethra that may be related to tissue integrity at the time of fixation. In this study we used tissue derived from rapid autopsies of female patients to determine the distribution of glandular structures expressing prostate-specific antigen (PSA) and prostate-specific acid phosphatase (PSAP) along the female urethra and in surrounding tissues, including the anterior vaginal wall (AVW). Tissue blocks from 7 donors that contained the entire urethra and adjacent AVW were analyzed. These tissue samples were fixed within 4-12hours of death and divided into 5-mm transverse slices that were paraffin embedded. Sections cut from each slice were immunolabeled for PSA or PSAP and a neighboring section was stained with hematoxylin and eosin. The sections were reviewed by light microscopy and analyzed using QuPath software. In tissue from all donors, glandular structures expressing PSA and/or PSAP were located within the wall of the urethra and were present along its whole length. In the proximal half of the urethra from all donors, small glands expressing PSAP, but not PSA, were observed adjacent to the and emptying into the lumen. In the distal half of the urethra from 5 of the 7 donors, tubuloacinar structures lined by a glandular epithelium expressed both PSA and PSAP. In addition, columnar cells at the surface of structures with a multilayered transitional epithelium in the distal half of the urethra from all donors expressed PSAP. No glands expressing PSA or PSAP were found in tissues surrounding the urethra, including the AVW. Greater understanding of the distribution of urethral glands expressing prostatic proteins in female patients is important because these glands are reported to contribute to the female sexual response and to urethral pathology, including urethral cysts, diverticula, and adenocarcinoma. Strengths of the present study include the use of rapid autopsy to minimize protein degradation and autolysis, and the preparation of large tissue sections to demonstrate precise anatomical relations within all the tissues surrounding the urethral lumen. Limitations include the sample size and that all donors had advanced malignancy and had undergone previous therapy which may have had unknown tissue effects. Proximal and distal glands expressing prostate-specific proteins were observed in tissue from all donors, and these glands were located only within the wall of the urethra.

Disagreement in Female Urethral Nomenclature: A Survey Study of Genitourinary Surgeons.

Introduction: Inconsistencies exist in the nomenclature pertaining to the terms dorsal and ventral female urethra. This survey study was devised to demonstrate this inconsistency, and to identify any surgeon characteristics that contribute to this confusion in urologic and gynecologic reconstructive surgeons.Methods: Genitourinary surgeons were anonymously surveyed using email and social media platforms and asked how they would anatomically label 2 distinctly indicated regions of the female urethra using "dorsal" and "ventral" nomenclature. χ2 statistical analyses were used to compare categorical responses.Results: We received a total of 155 responses: 128 urologists, 26 gynecologists, and 1 medical student. The medical student was excluded from the analysis. Responses to the red/dorsal marker were 48% dorsal, 27% ventral, and 25% free response. Responses to the green/ventral marker were 52% ventral, 26% dorsal, and 22% free response. Urologists were more likely than gynecologists to use the correct "dorsal" label (χ2 [1, N = 122] = 33.6, P < .00001) and "ventral" label (χ2 [1, N = 124] = 32.3, P < .00001). There was no statistically significant difference between attendings vs trainees responding either "dorsal" or "ventral" to describe the red marker (χ2 [1, N = 124] = 0.24, P < .63) or the green marker (χ2 [1, N = 122] = 0.21, P < .65).Conclusions: The terms dorsal and ventral female urethra are not consistent between urologist and gynecologist reconstructive surgeons, and efforts to standardize terminology should be made at the residency training level.

Female paraurethral leiomyoma: A lateral transvestibular approach to a symptomatic tumor

We report a rare case of leiomyoma of the female urethra. A 31-year-old married woman, gravid and para one with no history of prior surgery, malignancy or other significant disease was referred to our clinic with a complaint of a mass protruding from the top of the vagina and difficulty voiding from 18 months ago. The mass had a rapid growth causing urinary obstructive symptoms, dyspareunia which turned to a vast palpable mass protruding the vagina. A definite surgical excision was launched via a lateral transvestibular approach demonstrating no attachment to the urethral tract. The histopathology report confirmed spindle cell tumor consistent with leiomyoma. During the 6-month follow-up period, there was no tumoral recurrence, and neither initial obstructive symptoms nor emerging de-novo incontinency were not observed. In resection of such tumors, care should be taken to spare urethral sphincter in order to prevent future incontinency.

Skene’s gland abscess: a rare case report

Background: The Para urethral gland of Skene is a pair of glands in the vestibule on the distal two-thirds of the female urethra, they are homologous to the male prostate gland and are believed to secrete fluid that lubricates the urethral opening. They contain about 6 to 30 small glands. The grand’s duct can get infected and hence inflamed obstruct. The secretion may accumulate leading an abscess formation. The patients may develop fever, dysuria, or dyspareunia. On examination, there may be a visible palpable Para urethral mass which may be unilateral or bilateral, it may also be tender. The incidence of Skene’s gland abscess is unknown, it is common in premenopausal women usually in the third and fourth decades of life. Trans trans-perineal ultrasound scan is very useful in the diagnosis but MRI is the gold standard. An important differential diagnosis is urethral diverticulitis which can be distinguished using these imaging modalities. Case report: We present a 30 years old nulliparous single lady who had a 2-year history of vaginal swelling and superficial dyspareunia we made a final diagnosis of palpable skene’s gland abscess, which was treated by marsupialization.

Nitrergic inhibition of sympathetic arteriolar constrictions in the female rodent urethra.

During the urine storage phase, tonically contracting urethral musculature would have a higher energy consumption than bladder muscle that develops phasic contractions. However, ischaemic dysfunction is less prevalent in the urethra than in the bladder, suggesting that urethral vasculature has intrinsic properties ensuring an adequate blood supply. Diameter changes in rat or mouse urethral arterioles were measured using a video-tracking system. Intercellular Ca2+ dynamics in arteriolar smooth muscle (SMCs) and endothelial cells were visualised using NG2- and parvalbumin-GCaMP6 mice, respectively. Fluorescence immunohistochemistry was used to visualise the perivascular innervation. In rat urethral arterioles, sympathetic vasoconstrictions were predominantly suppressed by α,β-methylene ATP (10μM) but not prazosin (1μM). Tadalafil (100nM), a PDE5 inhibitor, diminished the vasoconstrictions in a manner reversed by N-ω-propyl-l-arginine hydrochloride (l-NPA, 1μM), a neuronal NO synthesis (nNOS) inhibitor. Vesicular acetylcholine transporter immunoreactive perivascular nerve fibres co-expressing nNOS were intertwined with tyrosine hydroxylase immunoreactive sympathetic nerve fibres. In phenylephrine (1μM) pre-constricted rat or mouse urethral arterioles, nerve-evoked vasodilatations or transient SMC Ca2+ reductions were largely diminished by l-nitroarginine (l-NA, 10μM), a broad-spectrum NOS inhibitor, but not by l-NPA. The CGRP receptor antagonist BIBN-4096 (1μM) shortened the vasodilatory responses, while atropine (1μM) abolished the l-NA-resistant transient vasodilatory responses. Nerve-evoked endothelial Ca2+ transients were abolished by atropine plus guanethidine (10μM), indicating its neurotransmitter origin and absence of non-adrenergic non-cholinergic endothelial NO release. In urethral arterioles, NO released from parasympathetic nerves counteracts sympathetic vasoconstrictions pre- and post-synaptically to restrict arteriolar contractility. KEY POINTS: Despite a higher energy consumption of the urethral musculature than the bladder detrusor muscle, ischaemic dysfunction of the urethra is less prevalent than that of the bladder. In the urethral arterioles, sympathetic vasoconstrictions are predominately mediated by ATP, not noradrenaline. NO released from parasympathetic nerves counteracts sympathetic vasoconstrictions by its pre-synaptic inhibition of sympathetic transmission as well as post-synaptic arteriolar smooth muscle relaxation. Acetylcholine released from parasympathetic nerves contributes to endothelium-dependent, transient vasodilatations, while CGRP released from sensory nerves prolongs NO-mediated vasodilatations. PDE5 inhibitors could be beneficial to maintain and/or improve urethral blood supply and in turn the volume and contractility of urethral musculature.

Возможности магнитно-резонансной томографии в диагностике воспалительных изменений парауретральных желез у женщин.

Introduction. Inflammation of the paraurethral glands (skеneitis) is a complex urological disease, often hidden under the guise of other pathological conditions and causing recurrent lower urinary tract infection (UTI) in women. A significant problem for the diagnosis of skineitis at present is the absence or extremely low sensitivity and specificity of available laboratory, instrumental and radiation methods. Thus, the search for new ways to examine patients with recurrent UTI caused by chronic inflammation of the Skene’s glands is an important clinical and socio-economic task of modern healthcare. Materials and methods. The study involved 30 patients aged from 24 to 51 years who underwent magnetic resonance imaging (MRI) of the pelvis with contrast enhancement and targeted examination of the urethra and periurethral area using a device with a 3T fi ld strength. To study the MR semiotics of chronic inflammation of the gallbladder, in addition to standard MR protocols, high-resolution T2-weighted images with a slice thickness of 2 mm and T2-weighted Space 3D images in a sagittal projection with a slice thickness of 1 mm were used. The first group consisted of 16 urologically healthy women without complaints of dysuria, who underwent an assessment of the MRI anatomy of the normal female urethra. MRI of 14 respondents with chronic infl mmation of the paraurethral glands (second group) was performed to search for recurring (natural) changes characteristic of this disease. Such parameters as the diameter of the urethra, the separate thickness of its anterior and posterior walls, clarity at the boundary of the layers, and the presence of pathological changes and formations were studied. Results. Analysis of the obtained tomograms showed that urologically healthy respondents are characterized by symmetrical thickness of the walls of the urethra without pathological formations in it, as well as evenness and clarity of the contour at the boundary of the layers. When studying the results of examination of patients with chronic skeneitis, all of them (100%) noted the following recurring changes: an increase in the diameter of the urethra due to thickening of its posterior wall, in particular the submucosal layer, impaired differentiation at the border of the submucosal and muscular layers, the presence of small cystic changes in the structure of the posterior wall of the urethra (85.7%) or fragmentarily dilated ducts of the urinary tract (14%). Hypertrophy of the bulbospongiosus muscles, detected in 85.7% of respondents in the second group, is likely an indicator of frequent exacerbations and duration of the disease, and can be considered as an additional nonspecific criterion for this disease. Conclusions. These changes can tentatively, given the small sample, be considered pathognomonic MR signs of chronic skineitis. Thus, MRI of the pelvis with a targeted examination of the urethra and periurethral area can help in the differential diagnosis of patients with suspected inflammation of the paraurethral glands, establishing the correct diagnosis and prescribing adequate treatment.

Outcomes of urethral meatal preservation ventral urethroplasty for female urethral stricture: a series of cases.

To present a series of cases with our initial experience and short-term outcomes of a modified vaginal mucosal flap urethroplasty. Patients diagnosed with urethral stricture and operated by the same operative technique between January 2012 and January 2018 were followed for at least 6 months. Uroflowmetry and clinical outcomes were evaluated. Nineteen patients were included with an average age of 56.4 years, mean preoperative Qmax of 5.3 ml/s, and PVR of 101.4 mL. After 6 months of the procedure, the mean Qmax improved to 14.7 mL/s (p<0.05), PVR decreased to 47.3 mL (p<0.05), and 84.2% of all patients reported improvement in clinical self-reported symptoms. There was an improvement in symptoms such as voiding effort in 84.2% of patients, weak stream (89.5%), and recurrent urinary tract infection (85.7%). The success rate (absence of symptoms and normal Qmax with no significant PVR) of the procedure was 84.2%. The described technique was considered effective for the treatment of female urethra stricture, with a high clinical success rate and an objective improvement of Qmax and decrease in PVR after 6 months of the procedure.

Воспаление парауретральных протоков и желез у женщин: проблема с 350-летней историей.

Introduction. Inflammation of the Skene glands is one of the common causes of persistent dysuria and recurrent lower urinary tract infections. Lack of awareness about this pathology can lead to diagnostic errors and inadequate treatment. This pathology is not sufficiently covered in the literature, which was the reason for preparing this lecture. Results. The lecture review covers the history of studying the anatomy of the paraurethral glands in women, the first attempts to diagnose and treat various diseases. The issues of homology of the paraurethral ducts and glands in women with the prostate gland in men are considered, the anatomy, morphology and immunohistochemical properties of the Skene glands are described, as well as modern ideas about their function. The historical background, nomenclature and classification are presented. The role of inflammation in these structures as a cause of persistent dysuria and a source of persistent lower urinary tract infections has been demonstrated. The need to standardize the methodology for examining patients with skineitis and the search for a specialized instrument for an adequate examination of the female urethra is substantiated. An analysis of the effectiveness of electrical resection of Skene's glands was carried out. Conclusions. One of the main factors behind unsatisfactory treatment results for lower urinary tract infections is inflammation of the paraurethral ducts and glands. Their insufficient visualization and assessment are the reasons for frequent relapses of the disease and repeated surgical interventions.

Management of the Devastated Female Urethra

Management of the Devastated Female Urethra

Which parameters, related to the female urethra and pelvic floor, determine therapy selection for recurrent female stress urinary incontinence: ICI-RS 2023?

The evidence basis for therapy selection in women who have failed primary stress urinary incontinence (SUI) surgery is limited. The ICI-RS group discussed the available data at its meeting in June 2023, particularly the anatomical characteristics as assessed using magnetic resonance imaging (MRI) and ultrasound (US) modalities, functional characteristics associated with storage and voiding urodynamic assessment, as well as the patient characteristics that might influence outcomes. This paper summarizes the evidence base that supported these discussions and offers the basis for research proposals for future groups. A literature search of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials was performed, and the data is presented. Research questions are based on the knowledge gaps highlighted. Possible MRI parameters that may influence outcomes were striated urethral sphincter volume, bladder and proximal urethral funneling, pubo-urethral ligament integrity, distance of the bladder neck below the pubococcygeal line, posterior urethra-vesical angle, and bladder neck to levator ani distance. US parameters included sling distance to the urethral lumen and pubis, sling position, bladder neck mobility, and lateral arm asymmetry, twisting, or curling. Urodynamic parameters included detrusor overactivity, Valsalva leak point pressure, maximum urethral closure pressure, and bladder outlet obstruction. Important patient parameters included body mass index, age, and previous interventions. Identifying and quantifying causative factors in patients with recurrent SUI, that allow clinicians to modify subsequent treatment choices and techniques may help reduce treatment failure and complications. Formulating algorithms is the next step in optimizing patient counseling, surgical selection, and healthcare allocation.

Mélanome primitif de l’urètre féminin : à propos d’un cas diagnostiqué à Ouagadougou

We report a case of primary melanoma of a female urethra diagnosed at a non-metastatic stage in a 48-year-old patient with a history of breast carcinoma treated with radiotherapy and hormone therapy. The patient was consulting for dysuria, hematuria, and perineal pain. The clinical examination found a prolapsed and black mass, developed at the expense of the urethra and located at the anterosuperior part of the vulva. The mass biopsy revealed a proliferation of fusiform and globular cells loaded with black pigment expressing the anti-HMB45and PS100antibodies. The extension assessment showed an absence of secondary localization. The patient underwent total cystourethrectomy without inguinal lymphadenectomy. There was no recurrence observed on day 100following the surgery.

Synovial sarcoma of female urethra: a case report and review of the literature

Synovial sarcoma (SS) is a rare malignant soft tissue sarcoma that originates from primitive mesenchymal cells with epithelial differentiation potential. It is most commonly found in the limbs and trunk. In the urinary system, it is mostly found in the kidneys. However, synovial sarcomas originating from the external urethra are extremely rare. Only one case of synovial sarcoma arising from the vulvar urethral orifice has been reported previously, and we report a second case of synovial sarcoma of the urethral orifice. In addition, a total of 16 vulvar synovial sarcomas were identified and the literature are analyzed in this report reviews from 1966 to the present.

Case Report: A rare case of mucinous adenocarcinoma of the female urethra

Background: Urethral adenocarcinoma is a very uncommon problem in women, with a prevalence of 0.02%. Due to the disease's rarity, there is very little information available about it. Treatment for cancer can have a significant negative influence on a patient's condition. Mucinous adenocarcinomas are a very uncommon type of cancer that is poorly studied. These cancers almost invariably have a worse outcome compared to conventional adenocarcinomas. Case Presentation: A 67 year old woman presented with hematuria and stranguria. A computerised tomography (CT) scan of this patient revealed an urethral tumor. In her histopathologic report we found the tumor cells were arranged in small clusters and single cells were scattered among extracellular mucin and signet ring cell picture, which is consistent with mucionous adenocarcinoma. We then performed partial urethrectomy with negative surgical resection, but the tumor reappeared 18 months later with no symptoms. The patient then decided to undergo radiotherapy for 33 sessions. From a recent MRI follow up the patient remains recurrence free. Conclusions: Early surgical treatment with or without adjuvant radiotherapy appears to be the best option in cases of small, organ-confined disease of urethral mucinous adenocarcinoma. Partial urethrectomy can be performed in this type of cases, which can prevent the use of permanent urinary catheters and further improve the patient's quality of life.

Primary clear-cell adenocarcinoma in women

Objectives: A literature review of clear cell adenocarcinoma (CCA) of the female urethra, which is a urinary tract neoplasm of low prevalence that can affect the urethra in rare occasions. Material and methods: A case report of CCA in a 59-year-old female with low urinary tract symptoms associated with two episodes of acute urinary retention and recurrent urinary tract infection (UTI) with the finding of a periurethral tumor in magnetic resonance image (MRI). Results: After cystectomy, double adnexectomy, urethrectomy, bilateral iliac-obturator lymphadenectomy, and ureteroileal deviation, the diagnosis of urethral CCA spread to lymph nodes was made. The case was discussed in the Urologic Oncology committee, indicating external radiotherapy and cisplatin as adjuvant treatment. Conclusions: Because of its aggressiveness, CCA is a rare tumor that requires radical surgery.

Diagnosis and treatment of primary urethral melanoma with regional lymphatic metastasis in an elderly woman: a case report and review of available therapies

BackgroundMucosal melanomas account for 17% of melanomas, and less than 1% affect the urogenital tract. Primary urethral melanoma is extremely rare; less than 200 cases have been reported so far since it was first described. The clinical presentation is usually delayed, and the prognosis is generally poor.Case presentation.An 86-year-old female was referred to urology due to the presence of a three-month-old violaceous mass in the urethral meatus protruding through the vagina. On physical examination, a pedunculated, hyperpigmented, friable, and tender lesion was seen in the urethral meatus bulging between the labia minora. After initial diagnostic studies, the patient was taken to surgical resection of the lesion. The pathology report identified the lesion as a malignant melanoma of the urethra, and staging studies revealed regional lymph node metastases. After discussing the treatment options with the patient, palliative therapy with nivolumab was started. In follow-up at 26 months, the patient had evidence of extensive lymph node involvement, but a conserved performance status and no visceral metastases.ConclusionPrimary melanoma of the female urethra is an uncommon disease with a poor prognosis. Despite the deficiency in literature regarding its management, it is important to consider patient expectations and preferences when treating this rare disease.

A deeper understanding of the cellular composition of female urethra in the non-diseased state could provide insights into the etiology of dysfunction. Single cell RNA sequencing was performed on female urethra to generate a cellular atlas. METHODS: Urethra from female organ donors aged 18-45 (N=4) was collected fresh from surgery and enzymatically digested into a single cell suspension. Single cell RNA sequencing was performed using 10x Genomics V3 chemistry. Data were analyzed in Seurat for cell type annotation. Immunohistochemical validation of cell types was performed on FFPE sections using differentially expressed genes from clustered data. RESULTS: The female proximal urethral lumen is lined with a stratified urothelium composed of KRT5+/KRT14- basal cells with KRT13+ hillock epithelia and KRT4+ luminal epithelia. Ducts emerging from dorsal urethra (Skene's glands) contain basal and club cells similar to prostatic urethra. The urethral lumen is surrounded by two discrete layers of fibroblasts (peri-urethral and interstitial) and circumferential smooth muscle and skeletal muscle. CONCLUSIONS: The identification of 1) specialized fibroblasts surrounding the urethra, and 2) club cells in dorsal ducts could yield new insight into the regulation of infection, inflammation and obstruction, which are the putative etiologies of most urethral dysfunction.
