Título: Urothelial neoplasm of the bladder in childhood and adolescence: a rare disease
Fonte: Int. braz. j. urol;42(2):242-246, Mar.-Apr. 2016. tab, graf.
Idioma: en.
Resumo: ABSTRACT Purpose: Bladder tumors are rare in children and adolescents. For this reason, the diagnosis is sometimes delayed in pediatric patients. We aimed to describe the diagnosis, treatment, and follow-up methods of bladder urothelial neoplasms in children and adolescents. Materials and Methods: We carried out a retrospective multicenter study involving patients who were treated between 2008 and 2014. Eleven patients aged younger than 18 years were enrolled in the study. In all the patients, a bladder tumor was diagnosed using ultrasonography and was treated through transurethral resection of the bladder (TURBT). Results: Nine of the 11 patients (82%) were admitted with gross hematuria. The average delay in diagnosis was 3 months (range, 0–16 months) until the ultrasonographic diagnosis was performed from the first episodes of macroscopic hematuria. A single exophytic tumor (1–4cm) was present in each patient. The pathology of all patients was reported as superficial urothelial neoplasm: two with papilloma, one with papillary urothelial neoplasm of low malignant potential (PUNLMP), four with low grade pTa, and four with low grade pT1. No recurrence was observed during regular cystoscopic and ultrasonographic follow-up. Conclusions: Regardless of the presence of hematuria, bladder tumors in children are usually not considered because urothelial carcinoma in this population is extremely rare, which causes a delay in diagnosis. Fortunately, the disease has a good prognosis and recurrences are infrequent. Cystoscopy may be unnecessary in the follow-up of children with bladder tumors. We believe that ultrasonography is sufficient in follow-up.

Título: Intraoperative breakage of Sachse's knife blade: A rare complication of optical internal urethrotomy (one case managing experience)
Fonte: Int. braz. j. urol;43(1):163-165, Jan.-Feb. 2017. graf.
Idioma: en.
Resumo: ABSTRACT Optical internal urethrotomy (OIU) is the most common procedure performed for short segment bulbar urethral stricture worldwide. This procedure most commonly performed using Sachse’s cold knife. Various perioperative complications of internal urethrotomy have been described in literature including bleeding, urinary tract infection, extravasation of fluid, incontinence, impotence, and recurrence of stricture. Here we report a unique complication of breakage of Sachse knife blade intraoperatively and its endoscopic management.

Título: Female sexual function following a novel transobturator sling procedure without paraurethral dissection (modified-TOT)
Fonte: Int. braz. j. urol;43(1):142-149, Jan.-Feb. 2017. tab, graf.
Idioma: en.
Resumo: ABSTRACT Purpose To determine whether there is a difference in sexual function after modified and classical TOT procedures. Materials and Methods Of the 80 sexually active women with SUI, 36 underwent an original outside-in TOT as described by Delorme, and 44 underwent modified TOT procedure, between 2011 and 2015. The severity of incontinence and sexual function were evaluated using International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and Female Sexual Function Index (FSFI) questionnaires preoperatively and 3 months after surgery. Results The postoperative ICIQ-SF score was significantly lower than the preoperative ICIQ-SF score in both groups (p=0.004 for modified TOT and p=0.002 for classical TOT). There was no significant difference in the ICIQ-SF score reduction between the two groups (14.1±2.1 vs. 14.4±1.9; p=0.892). Complication rates according to the Clavien-Dindo classification were also similar in both groups. In both groups, difference between preoperative and postoperative FSFI scores revealed a statistically significant improvement in all domains. Comparison of postoperative 3-month FSFI scores of modified and classical TOT groups showed statistically significant differences in arousal, lubrication and orgasm domains. Desire, satisfaction, pain and total FSFI scores did not differ significantly between two groups. Conclusion The modified TOT technique is a simple, reliable and minimal invasive procedure. The cure rate of incontinence and complication rates are the same as those of the classical TOT technique. However, due to the positive effects of minimal tissue damage on sexual arousal and orgasmic function, modified TOT has an advantage over the classical TOT.

Título: Cystoscopy-assisted laparoscopy for bladder endometriosis: modified light-to-light technique for bladder preservation
Fonte: Int. braz. j. urol;43(1):87-94, Jan.-Feb. 2017. tab, graf.
Idioma: en.
Resumo: ABSTRACT Introduction Endometriosis is a disease with causes still unclear, affecting approximately 15% of women of reproductive age, and in 1%-2% of whom it may involve the urinary tract. The bladder is the organ most frequently affected by endometriosis, observed around 85% of the cases. In such cases, the most effective treatment is partial cystectomy, especially via videolaparoscopy. Study Objective, Design, Size and Duration In order to identify and delimit the extent of the intravesical endometriosis lesion, to determine the resection limits, as well as to perform an optimal reconstruction of the organ aiming for its maximum preservation, we performed a cystoscopy simultaneously with the surgery, employing a modified light-to-light technique in 25 consecutive patients, from September 2006 to May 2012. Setting Study performed at Campinas Medical Center – Campinas – Sao Paulo – Brazil.Participants/materials, setting and methods: Patients aged 27 to 47 (average age: 33.4 years) with deep endometriosis with total bladder involvement were selected for the study. The technique used was conventional laparoscopy with a transvaginal uterine manipulator and simultaneous cystoscopy (the light-to-light technique). A partial videolaparoscopic cystectomy was performed with cystoscopy-assisted vesical reconstruction throughout the entire surgical time. The lesions had an average size of 2.75cm (ranging from 1.5 to 5.5cm). The average surgical time was 137.7 minutes, ranging from 110 to 180 minutes. Main Results Postoperative follow-up time was 32.4 months (12-78 months), with clinical evaluation and a control cystoscopy performed every six months. No relapse was observed during the follow-up period. Conclusions A cystoscopy-assisted partial laparoscopic cystectomy with a modified light-to-light technique is a method that provides adequate identification of the lesion limits, intra or extravesically. It also allows a safe reconstruction of the organ aiming for its maximum preservation.

Título: The learning curve of sting method for endoscopic injection treatment of vesicoureteral reflux
Fonte: Int. braz. j. urol;44(6):1200-1206, Nov.-Dec. 2018. tab, graf.
Idioma: en.
Resumo: ABSTRACT Objective: To identify how many endoscopic injection (EI) procedures, STING method, must be performed before reaching an ideal success rate when simulation training has not been received. Materials and Methods: The EI procedures performed by two pediatric urology fellows were investigated. The study excluded patients without primary VUR and those with previous EI or ureteroneocystostomy, lower urinary tract dysfunction, and/or duplicate ureters. The EIs used dextranomer hyaluronate and the STING method, as described by O'Donnell and Puri. Groups number was determined by multiple statistical trials. Statistically significance differences were achieved with one combination that had 35 EI procedures each and with 3 different combination of patients, having 12, 24, and 36 patients, respectively. Therefore, groups were established 12 patients. The first fellow performed 54 EIs, and the second performed 51. Therefore, each of the first fellow's three groups contained 18 EI procedures, and each of the second fellow's 17. Results: The study included 72 patients and 105 ureter units. When the data from both fellows were combined, each of the three groups contained 35 procedures. For the first fellow, the success rates in the first, second, and third groups were 38.3%, 66.6%, and 83.3% (p = 0.02), respectively, and for the second fellow, the success rates were 41.2%, 64.7%, and 82.3% (p = 0.045), respectively. The increased success rates for both fellows were very similar. Conclusions: An acceptable rate of success for EI may be reached after about 20 procedures and a high success rate after about 35-40 procedures.

Título: Idiosyncratic reaction after injection of polyacrylate - polyalcohol copolymer
Fonte: Int. braz. j. urol;44(4):831-834, July-Aug. 2018. graf.
Idioma: en.
Resumo: ABSTRACT Context: Polyacrylate-polyalcohol copolymer is a synthetic product, non-biodegradable, with low rate of therapeutic failure and lower incidence of reactions at the site of injection, when compared to biodegradable agents. We report an unprecedent, exuberant and persistent inflammatory reaction following injection of that substance. Patient: a 17 years-old patient with vesico-ureteral reflux and complete pyelocaliceal right duplication was submitted to treatment with polyacrylate-polyalcohol copolymer (STING technique). In the seventh day of post-operatory, she presented intense dysuria and hypogastric pain, without laboratory exams alterations; a symptomatic treatment was started. After two months, the symptoms persisted and an ultrasound detected thickening of bladder wall close to the uretero-vesical junction. After that exam, a cystostopic biopsy showed epithelial hyperplasia with increased edema of lamina propria, suggesting an adverse reaction to the polymer. After four months, there was complete remission, but the reflux persisted with the same grade. Hypothesis: This is an unprecedent reaction following injection of this copolymer. The presence of characteristics such as absence of infection, temporal relation between treatment and beginning of symptoms, and detection of epithelial hyperplasia at the local of injection reinforce the hypothesis of association of the substance and adverse reaction. In that patient, important complains motivated early investigation of urinary tract, that confirmed those aspects. Maybe if that reaction had occurred in patients with lower capacity of expression (such as in infants) it would be unnoticed.

Título: Nephrogenic adenoma of the bladder: a single institution experience assessing clinical factors
Fonte: Int. braz. j. urol;44(3):506-511, May-June 2018. tab, graf.
Idioma: en.
Resumo: ABSTRACT Introduction: Nephrogenic adenoma (NA) was first described by Davis in 1949 as a "hamartoma" of the bladder. There are many proposed predisposing factors for NA including chronic inflammation, renal transplantation, and bladder cancer. We examined our experience with NA to determine predisposing factors and determine if there was any increased risk for development of subsequent malignancy. Materials and Methods: All patients with a pathologic diagnosis of bladder NA from 2001-2013 were included. Patient history, clinical factors including possible predisposing factors for NA, and follow-up were reviewed. Results: Among 60 patients, 68% were males with an average age of 61, an average BMI of 28.7, and 60% had a smoking history. In evaluating pro-inflammatory factors, 26.7% underwent either Bacillus Calmette-Guerin or mitomycin C, 30% had recurrent urinary tract infections, and 25% had a history of catheterization. Recurrence of NA after initial resection occurred only in 14.7% of patients who underwent follow-up cystoscopy. A history of concurrent bladder cancer was seen in 41.7% of patients, but there were no cases of de novo bladder cancer diagnosed after NA. Conclusion: To the best of our knowledge, this is the largest series of patients with NA of the bladder. NA occurs in a heterogeneous population of patients, but most often with underlying inflammation. NA occurred concurrent with bladder cancer; however there were no cases of de novo bladder cancer after NA, reassuring that NA is likely a benign reactive condition.

Título: Removal of intramural trapped intrauterine device by cystoscopic incision of bladder wall
Fonte: Int. braz. j. urol;45(2):408-409, Mar.-Apr. 2019.
Idioma: en.
Resumo: ABSTRACT A healthy 37 - year - old woman referred to our clinic with one - year history of recurrent urinary tract infection, dysuria and frequency. Her past medical history informed us that an IUD (Copper TCu380A) had been inserted 11 years ago. Eleven months after the IUD insertion she had become pregnant, unexpectedly. At that time, she had undergone gynecological examination and abdominal ultrasound study. However, the IUD had not been found, and the gynecologist had made the diagnosis of spontaneous fall out of the IUD. She had experienced normal pregnancy and caesarian section with no complications. On physical examination, pelvic examination was normal and no other abnormalities were noted. Urinalysis revealed microhematuria and pyuria. Urine culture was positive for Escherichia coli. Ultrasound study revealed a calculus of about 10 mm in the bladder with a hyperdense lesion. A plain abdominal radiograph was requested which showed a metallic foreign body in the pelvis. We failed to remove the IUD by cystoscopic forceps because it had strongly invaded into the uterine and bladder wall. Despite previous papers suggesting open or laparoscopic surgeries in this situation (1, 2), we performed a modified cystoscopic extraction technique. We made a superficial cut in the bladder mucosa and muscle with J - hook monopolar electrocautery and extracted it completely with gentle traction. This technique can decrease the indication of open or laparoscopic surgery for extraction of intravesical IUDs. In the other side of the coin, this technique may increase the risk of uterovesical fistula. Therefore, the depth of incision is important and the surgeon should cut the bladder wall superficially with caution. Although present study is a case report which is normally classified as with low level of evidence, it seems that our modified cystoscopic extraction technique is a safe and useful method for extraction of partially intravesical IUDs.

Título: Non-functional paraganglioma of urinary bladder managed by transurethral resection
Fonte: Int. braz. j. urol;45(5):910-915, Sept.-Dec. 2019. graf.
Idioma: en.
Resumo: ABSTRACT Purpose As a rare bladder tumor, paraganglioma of the urinary bladder (PUB) is frequently misdiagnosed as bladder cancer, particularly for the non-functional type. To date, transurethral resection remains a controversial treatment for non-functional PUB. This study aimed to identify the clinical features, pathological characteristics, prognosis, and safe/effective treatment of non-functional PUB using transurethral resection of the bladder tumor (TURBT). Materials and Methods The clinical records, radiological data, pathological characteristics and follow-up times were retrospectively reviewed in 10 patients with clinically and pathologically proven non-functional PUB in our hospital from January 2008 to November 2016. All patients underwent TURBT treatment. Results The incidence of non-functional PUB in patients with bladder cancer was 0.17%. The mean age at diagnosis was 44.5 ± 13.6 years (range, 29-70 years), and the patient population had a female: male ratio of 3: 2. No patients had excess catecholamine (CA) whilst four patients had painless hematuria. All neoplasms were completely resected via TURBT. The majority of samples were positive for immunohistochemical markers including chromogranin A (CgA) and Synaptophysin (Syn), but were negative for cytokeratins (CKs). Only a single recurrence was observed from the mean follow-up period of 36.4 ± 24.8 months. Conclusion Complete TURBT is a safe and efficient treatment that serves both diagnostic and therapeutic purposes. Histopathological and immunohistochemistry examinations are mandatory for diagnostic confirmation. Long-term follow-up is recommended for patients with non-functional PUB.
