Clinical analysis of children with pathological phimosis treated by circumcision / 中华泌尿外科杂志

Objective:To investigate the clinical characteristics of pathological phimosis and analyze the correlation between pathological phimosis and balanitis xerotica obliterans(BXO) in children.Methods:The clinical data of 45 children who underwent circumcision and histopathologic evaluation in our hospital from July 2018 to August 2022 were retrospectively analyzed. According to the results of the pathological examination, lichen sclerosis et atrophicus cases were classified as the BXO group, and other cases were classified as the non-BXO group. The two groups' age, history, and symptoms were recorded and compared. The management of meatal stenosis and the effect of topical steroids were described.Results:There were 33 patients in the BXO group, aged (7.42±2.46)years old, of which 91% (30/33) were 5-11 years old. There were 12 patients in the non-BXO group, aged (10.42±2.88) years old. The difference of age between the two groups was statistically significant ( P< 0.05). But there was no significant difference between the BXO group and non-BXO group in the history of balanoposthitis(28 cases vs. 7 cases), history of foreskin dilated(15 cases vs. 3 cases), frequent urination (18 cases vs. 10 cases), urgent urination(12 cases vs. 4 cases), urination pain(17 cases vs. 3 cases), dysuria(21 cases vs. 5 cases), pruritus(25 cases vs. 7 cases), penile pain(7 cases vs. 1 case), ballooning(7 cases vs. 6 cases), and spraying (14 cases vs. 2 cases)( P > 0.05). All 8 cases of meatal stenosis were in the BXO group. Three cases underwent meatal dilatation and indwelling catheter was left for 5-10 days, and topical steroid was used on the third day after surgery. The remaining cases were treated with topical steroids after a pathological diagnosis of BXO. Among the 4 cases with partial urethral meatus involvement, 3 had good results after treatment, and 1 had no significant improvement and underwent meatal dilatation twice later. In 1 case, meatal stenosis was found two weeks after surgery, but no meatal abnormality was found during operation. All patients recovered smoothly during a median follow-up of 12.2 (5.4, 21.8) months. Conclusions:BXO is the main cause of pathologic phimosis in boys, and the diagnosis is based on histopathology. The main complication of BXO is meatal stenosis, which should be detected as early as possible and treated in time.

One case report of male genital lichensclerosus with urethrostenosis, perinral abscess and squamous cell carcinoma / 中华泌尿外科杂志

Male genital lichensclerosus has a hidden onset, which is easy to be ignored by doctors and patients. However, as the disease progresses, it can cause anterior urethral stricture, urinary fistula, perineal abscess and induce squamous cell carcinoma, which is extremely harmful. In February 2019, Rongcheng People’s Hospital treated a case of male genital sclerosing lichenoidosis with urethral stricture, perineal abscess and squamous cell carcinoma. After a variety of imaging, endoscopic examination and multiple pathological biopsy, the final diagnosis was confirmed, and then the cancer tissue was removed.

Urethral carcinoma accompanied by urethral stricture due to male genital lichen sclerosus / 中华泌尿外科杂志

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.

Balanitis xerótica obliterante en el adulto: A propósito de un caso / Balanitis xerotica obliterans: A case report in an adult

El liquen escleroso y atrófico (LE y A) del pene, también conocido como balanitis xerótica obliterante (BXO), es una enfermedad inflamatoria crónica del pene que puede ocurrir a cualquier edad. La inflamación conduce a la formación de placas hipocrómicas, más comúnmente en el prepucio o en el glande. En general puede causar fimosis, prurito, dolor por las fisuras, disuria, restricción de la micción, dispareunia y disfunción sexual significativa. Comunicamos un caso de BXO asociado a vitiligo en un paciente de 78 años, quien consultó por dispareunia. Fue derivado a Urología para resolución quirúrgica, donde se realizó una postectomía, cuyo estudio era compatible con una BXO. Muchos hallazgos obtenidos en los últimos años apuntan cada vez más, hacia un origen autoinmune de esta enfermedad. El uso de corticoides tópicos de alta potencia es todavía la mejor terapéutica, siendo la cirugía un buen tratamiento en casos muy severos, con fimosis importante o aquellos que no responden al uso de corticoides o inhibidores de la calcineurina, como el tacrolimus o pimecrolimus.

Lichen sclerosus et atrophicus (ALE) of the penis, also known as balanitis xerotica obliterans (BXO) is a chronic inflammatory disease of the penis that can occur at any age. The inflammation leads to the formation of hypochromic plaques, most commonly in the foreskin or on the glans. BXO can cause phimosis, pruritus, pain, dysuria, urinary restriction, dyspareunia, and significant sexual dysfunction. We present a case of BXO associated to vitiligo in a 78 years old patient, who consulted for dyspareunia. It was referred to urologist for surgical resolution, where circumcision was performed with biopsy compatible with BXO. In recent years studies have found that it could exists, an autoimmune ethiopathogenic factor of the disease. The topical use of high power corticosteroids is still the first choice and surgery remains a good treatment in severe cases (ex. phimosis) or those who do not respond to steroids.

Perineostomy: the last oportunity

Objective To review the technique and outcome of perineal urethrostomy or urethral perineostomy and to identify factors related to the procedure failure. Material and methods We studied 17 patients who underwent perineal urethrostomy between 2009-2013 in a single hospital. Success was defined as no need for additional surgical treatment or urethral dilatation. We reviewed the clinical data related to age, weight, previous urethral surgery, diabetes, hypertension, ischemic cardiopathy, lichen sclerosus and other causes and studied their association with the procedure failure (univariate analysis). We completed the analysis with a multivariate test based on binary regression. Results The average follow-up was 39.41 months. From all the causes, we found Lichen Sclerosus in 35%, idiopathic etiology in 29% and prior hypospadia repair in 18%. Postoperative failure occurred in 3 patients, with a final success of 82.4%. The binary regression model showed as independent risk factors ischemic cardiopathy (OR: 2.34), and the presence of Lichen Sclerosis (OR: 3.21). Conclusions The success rate with the perineal urethrostomy technique shows it to be a valid option above all when we preserve the urethral blood supply and plate. Lichen sclerosus and ischemic vascular problems are risk factors to re-stenosis. .

Clinical outcome of urethroplasty using free mucosal grafts for the treatment of urethral stricturecaused by lichen sclerosus / 中华泌尿外科杂志

ObjectiveTo improve the recognition of lichen sclerosus (LS) involving the anterior urethral strictures and to investigate the outcome of urethroplasty using free mucosal grafts for the treatment of urethral strictures caused by LS. MethodsFrom January 2007 to December 2010,36 patients with anterior urethral strictures caused by LS were treated using oral mucosal grafts or colonic urethroplasty.The mean age was 41 years (range,27 -75) and the mean anterior urethral stricture length was 11.5 cm (range,5.0 -20.0 cm).Of the 36 patients,27 patients underwent dorsal lingual mucosal graft or combined buccal mucosal graft urethrography.Eight patients underwent colonic mucosal urethrography according to the length and seriousness of urethral strictures,and the remaining patient underwent anterior urethral split.Biopsies were taken from the glans,urethral meatus and urethra before urethroplasty. ResultsThe urethral silicone stent was removed 21 d post-operatively and all the patients voided well.An epithelial-stromal lesion characterized by hyperkeratosis,thinned epithelium and diffuse perivascular lymphocyte infiltrate was seen upon histological examination of the biopsied areas.The mean follow-up was 22 ( range,6 - 50) months post-operatively.Meatal stenosis developed in 2 patients undergoing oral mucosas urethroplasty and 1 patient with colonic urethroplasty,the patients voided very well after re-operation.The other patients voided well and the urinary peak flow rates ranged from 17.2 to 47.0 mL/s ( mean,23.4). ConclusionsFree mucosal grafts urethroplasty can obtain good results for the treatment of urethral strictures caused by LS.But there is a risk of recurrence of urethral stricture and closing follow-up is required,especially for meatal stenosis.

Balanitis Xerotica Obliterans with Primary Urethral Stone, A Case Report / 대한비뇨기과학회지

Balanitis xerotica obliterans is a condition of unknown etiology with a specific clinical and histological character. It is a condition affecting the glans penis and prepuce which Stuhmer in 1928 first reported as occurring predominantly in young men following circumcision for phimosis. We report an unusual case of balanitis xerotica obliterans which developed on penis with primary urethral stone
