ABSTRACT
Fundamento: El cáncer primario de uretra se define como el tumor cuya primera lesión se localiza en la uretra; es infrecuente, el mismo representa menos del 1 % de los tumores malignos y el 5 % de los tumores malignos del sistema urinario. La extensión de este proceso a la glándula prostática genera sintomatología urinaria obstructiva e irritativa y cuadros agudos como la hematuria macroscópica. Objetivo: Presentar el caso de un paciente con cáncer primario de uretra en su variedad urotelial con hematuria macroscópica como forma clínica de presentación. Presentación del caso: Caso clínico de un paciente masculino de 75 años de edad, con hematuria macroscópica como forma clínica de presentación de cáncer primario de uretra en su variedad urotelial, el cual se diagnosticó anatomopatológicamente durante el estudio de la hematuria. Conclusiones: El caso que se presenta permite alertar a la comunidad científica que en pacientes que presentan hematuria macroscópica, sin manifestaciones urológicas obstructivas ni irritativas, también debe tenerse en cuenta el diagnóstico de cáncer uretral primario, aunque sea un signo infrecuente como forma clínica de presentación de esa enfermedad.
Background: Primary urethral cancer is defined as a tumor whose first lesion is located in the urethra; is very uncommon, represents less than 1% of malignant tumors and 5% of malignant tumors of the urinary system. The extension of this process to the prostate gland creates obstructive and irritative urinary symptoms and acute conditions such as macroscopic hematuria. Objective: To present the case of a patient with primary urethral carcinoma in its urothelial variety with macroscopic hematuria as clinical presentation. Case presentation: Clinical case of a 75-year-old male patient, with macroscopic hematuria as a clinical presentation of primary cancer of the urethra in its urothelial variety, diagnosed anatomopathologically during the hematuria study. Conclusions: The case presented alerts the scientific community that the diagnosis of primary urethral cancer should be considered in patients with macroscopic hematuria in the absence of obstructive or irritative urologic manifestations, although it is a rare sign as clinical presentation of this disease.

Male primary adenocarcinoma of urethra is rare clinically. A patient with primary adenocarcinoma of posterior urethra complicated with intestinal metaplasia was admitted and underwent urethral mass resection. The tumor recurred 3 months after surgery and no further treatment was given for personal reasons. The purpose of this report is to improve clinicians' understanding of urethral cancer, so that patients can undergo more accurate diagnosis and treatment.
ABSTRACT
Objective:To investigate the clinical features, diagnosis, treatment and prognosis of primary urethral carcinoma.Methods:The clinical and follow-up data of 12 patients with primary urethral carcinoma admitted to Beijing Hospital from July 2016 to December 2020 were retrospectively analyzed.Results:There were four males and eight females, with an average age of 66.3(53~75)years.Nine patients underwent magnetic resonance examination before operation, and eight patients presented with abnormal urethral signals.The clinical stage of female patients was generally later than those of male patients, and all patients received surgical treatment.Four male patients did not receive post-operative adjuvant treatment, and all of them attained disease-free survival.Among the eight female patients, four patients received postoperative adjuvant radiotherapy or chemotherapy, five patients had recurrence or metastasis during follow-up, and two patients died.Conclusions:The clinical stage of female urethral cancer is later than that of male.MRI examination is beneficial to the determination of local invasion of urethral cancer.For female proximal urethral cancer and male posterior urethral cancer, radical resection has a good therapeutic effect.
ABSTRACT
Primary female urethral adenocarcinoma is rare. This paper reports a case of primary urethral mucinous adenocarcinoma complicated with signet ring cell carcinoma. The patient underwent urethral tumor resection in another hospital. Postoperative examination indicated that the tumor remained, and the tumor was completely removed after urethral tumor resection. After 11 months of follow-up, there was no tumor residue or recurrence.
ABSTRACT
Objective:To investigate the characteristics and the management of male genital lichen sclerosus (MGLSc)accompanied by urethral carcinoma.Methods:A retrospective analysis was performed on 16MGLSc accompanied by urethral carcinoma patients who were referred to Shanghai Sixth People’s Hospital between June 2000 and August 2019. The average age was 53.7 (45-69) years. All of the patients had a mean history of MGLSc 15(6-35) years, anterior urethral stricture received urethral dilatation and other inappropriate urethrotomy treatment for 10 (8-15) years. There were 5 cases of solid mass 4.5 (3-7) cm in scrotum, accompanied by obviously pain. There were 11 cases of infective masses 6(4-10)cm in the perineum, and the masses were ulcerated with purulent secretions and residue-like pus mixed with necrotic tissues draining from the wounds. Urethrocutaneous fistula developed in 9 cases, and the secretions in the fistula cannot heal. The diseased tissue was confirmed by pathology as the metastasis of invasive urothelial carcinoma in 12 patients and urethral squamous cell carcinoma in 4 patients. 9 cases of tumor invaded corpus spongiosum or corpus cavernosum, 5 cases invaded corpus spongiosum or corpus cavernosum, with enlarged firm one side inguinal node. 2 cases of tumor invaded corpus cavernosum, beyond prostatic capsule and bladder neck, bilateral palpable inguinal lymph nodes metastasis were found, one case found tumor involved the left testis. 9 cases were T 2-3N 0M 0, 5 cases T 2-3N 1M 0, 1 case T 3N 2M 0, 1 case T 4N 2M 1. 5 patients with substantial tumors located in the scrotum, penile-sparing scrotum tumor, urethral tumor resection and urethrostomy was performed in 2 patients. Partial phallectomy, urethral tumor resection and perineal urethrostomy were performed in 3 patients. 11 patients with urethral cancer complicated with perineal infectious mass, 2 patients underwent extensive resection of the tumor and suprapubic cystostomy. 8 cases with perineal tumor infection complicated with urethrocutaneous fistulas formation, of which 2 patients received perineal mass, urethral tumor, fistula resection and suprapubic cystostomy, 4 patients with unilateral inguinal lymph node metastasis and received perineal mass, urethral tumor, fistula, lymph node resection and suprapubic cystostomy. 2 patients with bilateral inguinal node metastasis underwent total phallectomy and urethrectomy, inguinal lymph node resection and suprapubic cystostomy. One case of perineal infectious mass with urethral cutaneous fistula and unilateral inguinal lymph node metastasis (T 2-3N 1M 0) gave up tumor resection. Results:The pathological examination of surgical resection of the glans and urethra showed typical MGLSc manifestations as epithelial keratinization, basal cell vacuoles degeneration, dermis lymphocyte infiltration. The pathological examination of the surgical excised diseased urethra and surrounding tumor tissue showed invasive urothelial carcinoma in 12 patients. Immunohistochemical staining showed positive expression of P53, Ki-67 and GATA3. 4 patients of urethral squamous carcinoma and immunohistochemical staining showed positive expression of Ki-67, P40 and GATA3. All patients received cisplatin combined with gemcitabine chemotherapy for an average of 4.8 (2-6)courses and received local radiotherapy (50-70Gy/5w). The mean postoperative survival time of the 16 patients was 26 (3-48) months, and the survival time of urethral transitional cell carcinoma and squamous cell carcinoma was 29 (18-48) months and 18 (3-24) months, respectively. All patients died of tumor metastasis, with 6 patients of lung metastsis, 2 patients of lumbar and bone metastasis, 3 patients of liver metastasis, 2 patients of brain metastasis and 3 patients of lung combined with bone metastasis.Conclusions:MGLSc can cause urethal stricture and urethral carcinoma. The clinical manifestations are dysuria, urinary tumor, repeated infection and urethral fistula. Tumor excision and urinary diversion are common surgical methods. Urethral transitional cell carcinoma and squamous cell carcinoma are common pathological types. Postoperative combined radiotherapy and chemotherapy can be used, but the overall prognosis is poor.
ABSTRACT
Objective The cyst excision is considered as priority management of the female paraurethral cyst.The purpose of this present study was to explore the feasibility and safety of the two-step excision with treatment for the female paraurethral cyst.Methods Twenty eight consecutive women with paraurethral cyst underwent paraurethral cyst removal were enrolled retrospectively in this study from October 1,2005 to August 12,2008 in Urology Department of West China Hospital.Results All cases were followedup from 6 months to 2 years,no recurrence occurred.No complications such as urethral stricture and urethralvaginal fistula were found.Conclusions The 2-step excision is the reference technique for cure of female paraurethral cyst.Urethra injury was avoided efficiently,because anatomical relationship between cyst and urethra could be clearer when the technique of 2-step excision was applied.
ABSTRACT
Objective To investigate the feasibility and efficacy of the first stage anastomosis using perineal ring-shaped flap in the treatment of anterior urethral defect after bladder-preserving urinary continence anterior urethral resection in female patients with early urethra carcinoma. Methods Tweenty-nine female patients with early urethra malignant tumor diagnosed in Changhai Hospital, Second Military Medical University from Jan. 2013 to Jan. 2016 were enrolled in this study. The average age of the patients was (61.4±14.4) years old, the clinical stages were type and the lesions were limited to half of the urethra. All patients underwent bladder-preserving urinary continence anterior urethral resection. After the resection of tumor, a free 30-40 mm long ring-shaped flap from the perineal vestibule was anastomosed inline to the end of the urethra. The clinical feasibility and safety of the operation were evaluated. Results The operation time was 0.45-1.50 h, with an average of (0.51±0.30) h. The postoperative urethral orifice shape of patients was close to the physiological shape with unobstructed urination, and the maximum urination rate was 12.8-33.0 mL/s, with an average of (19.3±8.7) mL/s. The success rate of one-stage operation was 100%, without any urethral stricture or urinary incontinence. All patients were followed up for 12-48 months with an average of (32.6±3.5) months. During follow-up, 1 case (1/6) with squamous cell carcinoma had a positive left inguinal lymph node metastasis in the first 2 years after surgery, and died of extensive lung metastasis 3 years after surgery; 1 case diagnosed with metastatic squamous cell carcinoma by postoperative pathological report developed regional swollen lymph nodes in the groin 13 months after surgery, and then ilioinguinal lymphadenectomy was perform to dissect the lymph nodes. No other recurrence was found during follow-up. Conclusion The first stage anastomosis surgury using perineal ring-shaped flap is safe and effective in the treatment of anterior urethral defect after bladder-preserving urinary continence anterior urethral resection in female patients with early urethra carcinoma.
ABSTRACT
ABSTRACT The urethral adenocarcinoma is a rare malignant tumor that affects predominantly women. Its incidence is higher after the age of 50 in this group. The knowledge about this disease is limited due to its low frequency and is mainly based on case reports. Although rarely presenting distant metastasis, the clinical consequences of treating this condition may bring an important negative impact on patient's quality of life. This is mainly due to mutilating surgery and the need to use permanent urinary catheter. It is presented a case report of a patient with urethral adenocarcinoma and its therapeutic management.
RESUMO O adenocarcinoma de uretra é uma rara neoplasia maligna, que ocorre predominantemente em mulheres. Nesse grupo, sua incidência é maior a partir dos 50 anos. O conhecimento acerca da doença é limitado pela sua infrequência e baseia-se, sobretudo, em relatos de caso. Apesar de raramente apresentar metástase a distância, as consequências clínicas do tratamento dessa condição podem trazer forte impacto negativo na vida da portadora, em decorrência de cirurgias mutiladoras e da necessidade de uso de sonda vesical permanente. Apresenta-se um relato de caso de uma paciente com adenocarcinoma uretral e sua condução terapêutica.
ABSTRACT
Urethral tumors are rare and aggressive. They usually affect men (2:1) and occur more commonly in white (85% of cases). Soft tissue sarcomas are a heterogeneous group of tumors that arise from embryonic mesoderm. It represents 1% of all cases of urinary tract malignancies and rarely primary affect the ureter. We report a case of male urethral sarcoma. To date, only two similar cases have been published in literature.
Os tumores de uretra são muito raros e bastante agressivos. Acometem mais frequentemente homens (2:1) e são mais comuns na raça branca (85% dos casos). Os sarcomas de tecidos moles são um grupo heterogêneo de tumores que surgem a partir da mesoderme embrionária e representam 1% de todos os casos de doença maligna urinária, raramente acometendo a uretra primariamente. Relamos aqui um caso extremamente raro de sarcoma uretral masculino com somente dois semelhantes publicados na literatura.

Objective To evaluate the efficacy and feasibility of 125I radioactive seed interstitial implantation for the local advanced urinary tract epithelial carcinoma without total resection.Methods The clinical data of 21 patients with local advanced urothelial carcinoma without completely surgical resection who were treated by 125I radioactive particles implantation were retrospectively analyzed.The patients were divided into two groups and received preoperative plan.In group A, 14 patients received implants during operations, including 7 bladder transitional cell carcinoma patients who underwent a transurethral resection surgery or partial bladder resection and another 7 ureteral carcinoma cases who underwent semi urine road resection.After these operations, all of patients had tumor residues.After furthest resection of the tumor, the 125I seeds were implanted at the residual suspicious tumors and their surroundings.In group B, 7 patients were implanted under the guidance of color ultrasound or CT.According to the evaluation criteria of solid tumor in 2009, the tumor remission rate, survival rate, distribution and the mobile information of the particles were observed.Results The operations were successfully completed in all of 21 patients, and serious complications did not appear during the operation.Particle distribution and lesions were basic coincidence.A total of 2 particles displaced, but every patient had no adverse reactions.There were 2 patients with local fever after operation within 4 months, while the rest of patients had no adverse reactions.After median follow-up for 36 months (3-75 months) , the 1-year survival rate was 100.0 ％ (21/21), the 2-year survival rate was 90.5 ％ (19/21), and the 3-year survival rate was 61.9 ％ (13/21).The tumor remission rate of group A was 85.7 ％ (12/14) after 6-9 months, and was 42.9 ％ (6/14) after 12 months.The bladder was preserved in 7 cases with bladder tumors with the 2-year survival rate of 100.0 ％ (7/7) and the 5-year survival rate of 71.4 ％ (5/7).The tumor remission rate of group B after 6-9 months was 71.4 ％ (5/7), and was 42.9 ％ (3/7) after 12 months.Conclusion 125I seed implantation is a good choice for locally advanced urothelial carcinoma with high local tumor control rate, which is expected to be applied in the individual treatment of advanced urothelial cancer.
ABSTRACT
The aim of this study was to evaluate female urethral cancer (UCa) patients treated and followed-up during a time period spanning more than 20 yr at single institution in Korea. We reviewed medical records of 21 consecutive patients diagnosed with female UCa at our institution between 1991 and 2012. After exclusion of two patients due to undefined histology, we examined clinicopathological variables, as well as survival outcomes of 19 patients with female UCa. A Cox proportional hazards ratio model was used to identify significant predictors of prognosis according to variables. The median age at diagnosis was 59 yr, and the median follow-up duration was 87.0 months. The most common initial symptoms were voiding symptoms and blood spotting. The median tumor size was 3.4 cm, and 55% of patients had lesions involving the entire urethra. The most common histologic type was adenocarcinoma, and the second most common type was urothelial carcinoma. Fourteen patients underwent surgery, and 7 of these patients received adjuvant radiation or systemic chemotherapy. Eleven patients experienced tumor recurrence after primary therapy. Patients with high stage disease, advanced T stage (> or =T3), and positive lymph nodes had worse survival outcomes compared to their counterparts. Particularly, lymph node positivity and advanced T stage were significant predictive factors for all survival outcomes. Tumor location was the only significant predictor for recurrence-free survival. Although our study included a small number of patients, it conveys valuable information about this rare female urologic malignancy in a Korean population.

Here we report a case of primary carcinoma of the female urethra. A 52-year-old woman presented with a palpable urethral mass associated with intermittent pain that she first experienced a few months prior. Clinical examination showed a urethral mass that appeared to be a caruncle; therefore, simple carunclectomy was performed. However, on histological examination, the mass was revealed to be a squamous cell carcinoma; therefore, anterior urethrectomy was performed. During a 4-year follow-up period, the patient has been well with no dysuria, dyspareunia, or incontinence.

Objective To evaluate treatment results and prognostic factors of 47 patients withprimary urethral transitional cell carcinoma treated with post-operative adjuvant radiotherapy. Methods From October 1998 to October 2008, 47 patients with primary urethral transitional cell carcinoma received postoperative adjuvant radiotherapy. Thirty-one patients had stage T_3/T_4 disease, 7 had lymph node metastasis. Thirty-nine patients had G3 tumor, 13 had stump-positive. The median radiotherapy dose was 60 Gy (36-64 Gy). 81% patients (38/47) were treated with regional irradiation. Results The median follow-up time was 21 months (6 -88 months). The follow-up rate was 92%. The median overall survival time was 35 months (5 -88 months). The 2-and 5-year overall survival rates were 57% and 49%, respectively. In univariate analysis, the median overall survival time was better in patients with stage T_1 or T_2 compared with stage T_3 or T_4 tumor (42 months vs. 19 months,Χ~2 =7. 28,P=0. 007), with age of ≤65 years compared with >65 years (28 mouths vs 18 months,Χ~2 =8.23 ,P =0. 004). There was no significantdifference in the long term survival in patients with non-radical surgery compared with radical mastectomy (21 months vs. 20 months, Χ~2 = 0. 90, P = 0. 344). In multivariate analysis, the stage T_3 or T_4 (Χ~2 = 7. 89, P =0. 005), >65 years old (Χ~2 = 4.85, P = 0. 028), renal pelvis involvement (Χ~2= 5.65, P = 0. 018), and tumor located in the mid or inferior segment (Χ~2=6. 08 ,P =0. 014) were factors associated with poorer prognosis. Conclusions Postoperative adjuvant radiotherapy can improve the efficacy of patients with locally advanced urethral transitional cell carcinoma. Advanced T stage and > 65 years age are associated with poorer prognosis.
ABSTRACT
Objective To explore the surgical treatment of urethral recurrence after neobladder reconstruction in patients with bladder cancer. Methods In 89 consecutive patients with radical cystectomy, 5 patients (5.6%) presented with a noninvasive urethral recurrence at a median of 18 months (range 9 to 32 months). All 5 patients were treated by transurethral resection and intraurethral instillation with hydroxycamptothecin used as initial therapy. Mean follow-up was 37 months (24 - 52 months). Results All the 5 patients survived after the treatment. There was no one showed recurrence or distant metastasis. All the 5 cases achieved continence. Conclusion Urethral preservation at initial therapy for incipient noninvasive urethral recurrence would be a good choice and could maintain the quality of life.
ABSTRACT
Objective:To assess the clinical utility of a fluorescence in situ hybridization(FISH) assay as a non-invasive method for diagnosing and monitoring urothelial carcinoma(UC) in the upper urinary tract(UUT).Methods:Urine specimens from 63 consecutive patients with UUT-UC and 69 controls with benign disease were analyzed by means of cytology and FISH.For FISH analysis,labeled probes specific for chromosomes 3,7,and 17 and for the p16(9p21) gene were used to assess chromosomal abnormalities indicative of malignancy.Sensitivity and specificity of both techniques were determined and compared.The frequency of chromosomal aberrations of malignant cells from UUT-UC was also determined.Results:Of 63 patients with UUT-UC,FISH affords an overall sensitivity of 84.1%(53/63),the figure being 71.4%(20/28)for PTa and PT1 tumors,94.3%(33/35) for PT2-4 tumors.The sensitivities of urine cytology were 35.7%(10/28)for PTa and PT1 tumor,45.7%(16/35)for PT2-4 tumors,with an overall sensitivity of 41.3%(26/63).The sensitivities of the two methods for the low grade tumors were 80%(20/25)and 44%(11/25),and for high grade tumors were 86.8%(33/38)and 39.5%(15/38),respectively.Specificities for FISH and urine cytology were 91.3%(63/69)and 94.2%(65/69)respectively.Conclusion:According to the results,the sensitivity of FISH for the detection of UUT-UC is superior to that of urine cytology and the specificities of FISH and urine cytology are not significantly different.FISH can promote the diagnosis of UUT-UC,especially for the low stage and low grade cases,it may be a new promising non-invasive method for the diagnosis of UUT-UC.
