RESUMEN

BACKGROUND: Prolonged laparoscopic nephroureterectomy (LNU) for upper tract urothelial cancer (UTUC) can increase the frequency of intravesical recurrence after surgery. Therefore, it is important for urological surgeons to have knowledge on preoperative risk factors for prolonged LNU. However, few studies have investigated the risk factors for prolonged LNU. We hypothesized that the quantity of perirenal fat affects the pneumoretroperitoneum time (PRT) of retroperitoneal LNU (rLNU). This study aimed to investigate the preoperative risk factors for prolonged PRT during rLNU. METHODS: We reviewed the data of 115 patients who underwent rLNU for UTUC between 2013 and 2021. The perirenal fat thickness (PFT) observed on preoperative computed tomography (CT) images was used to evaluate the perinephric fat quantity. Preoperative risk factors for PRT during rLNU were analyzed using logistic regression models. The cutoff value for PRT was determined based on the median time.The cutoff values for fat-related factors influencing PRT were defined according to receiver operating characteristic curve analysis. RESULTS: The median PRT for rLNU was 182 min (interquartile range, 155-230 min). The cutoff values of posterior, lateral, and anterior PFTs were 15 mm, 24 mm, and 6 mm, respectively. Multivariate analysis revealed that a posterior PFT ≥ 15 mm (odds ratio [OR], 2.72; 95% confidence interval, 1.04-7.08; p = 0.0410) was an independent risk factor for prolonged PRT. CONCLUSIONS: Thick posterior PFT is a preoperative risk factor for prolonged PRT during rLNU. For patients with UTUC and thick posterior PFT, surgeons should develop optimal surgical strategies, including the selecting an expert surgeon as a primary surgeon and the selecting transperitoneal approach to surgery or open surgery.

RESUMEN

BACKGROUND: The Vesical Imaging Reporting and Data System (VI-RADS) is widely used for predicting muscle-invasive bladder cancer (MIBC). This study aimed to determine the clinicopathological significance of the VI-RADS ≧4 (VI≧4) group. METHODS: Patients who underwent transurethral resections of bladder tumors during the study period and preoperative magnetic resonance imaging were considered. The patients were pathologically diagnosed with urothelial carcinoma (UC). We first compared the results of patients with VI-RADS scores of 3 and 4 to determine the cut-off score for MIBC; thereafter, the patients were divided into the VI≧4 and VI-RADS ≦3 (VI≦3) groups using VI-RADS. The clinicopathological significance of the VI≧4 group was examined retrospectively by comparing the characteristics of each group. RESULTS: In total, 121 cases were examined, of which 28 were pathologically diagnosed with MIBC. Of the 28 MIBC cases, three (10.7%) had a VI-RADS score of ≦3, and 25 (89.3%) had a VI-RADS score of ≧4. Of the 93 NMIBC cases, 86 (92.5%) had a VI-RADS score of ≦3, and seven (7.5%) had a VI-RADS score of ≧4. The diagnostic performance of the VI-RADS with a cut-off score of 4 was 89.3% for sensitivity, 92.5% for specificity, and an area under the curve (AUC) of 0.91. Contrastingly, for a cut-off score of 3, the sensitivity was 89.3%, specificity was 62.0%, and AUC was 0.72. A VI-RADS score of ≥ 4 could predict MIBC. In the VI≧4 group, 30 of 32 (93.8%) patients had high-grade tumors. The VI≧4 group had significantly more high-grade bladder cancers than the VI≦3 group (p < 0.001 OR = 31.77 95%CI:8.47-1119.07). In addition, the VI≧4 group had more tumor necrosis (VI≧4 vs VI≦3, p < 0.001 OR = 7.46 95%CI:2.61-21.34) and more UC variant cases (VI≧4 vs VI≦3, p = 0.034 OR = 3.28 95%CI:1.05-10.25) than the VI≦3 group. CONCLUSIONS: This study suggests that VI-RADS has a high diagnostic performance in predicting MIBC and that VI-RADS could diagnose high-grade tumors, necrosis, and UC variants.

RESUMEN

BACKGROUND: One of the major concerns of patients with upper tract urothelial carcinoma (UTUC) treated with nephroureterectomy is intravesical recurrence (IVR). The purpose of the present study was to investigate the predictive risk factors for IVR after retroperitoneoscopic nephroureterectomy (RNU) for UTUC. METHODS: Clinicopathological and surgical information were collected from the medical records of 73 patients treated with RNU for non-metastatic UTUC, without a history of or concomitant bladder cancer. The association between IVR after RNU and clinicopathological and surgery-related factors, including preoperative urine cytology and pneumoretroperitoneum time, was analyzed using the Fisher exact test. RESULTS: During the median follow-up time of 39.1 months, 18 (24.7%) patients had subsequent IVR after RNU. The 1- and 3-year IVR-free survival rates were 85.9% and 76.5%, respectively. The Fisher exact test revealed that prolonged pneumoretroperitoneum time of ≥ 210 min was a risk factor for IVR in 1 year after RNU (p = 0.0358) and positive urine cytology was a risk factor for IVR in 3 years after RNU (p = 0.0352). CONCLUSIONS: In UTUC, the occurrences of IVR in 1 and 3 years after RNU are highly probable when the pneumoretroperitoneum time is prolonged (≥ 210 min) and in patients with positive urine cytology, respectively. Strict follow-up after RNU is more probable recommended for these patients.

RESUMEN

BACKGROUND: Transrectal ultrasonography (TRUS)-guided prostate biopsy is the conventional method of diagnosing prostate cancer. TRUS-guided prostate biopsy can occasionally be associated with severe complications. Here, we report the first case of a prostate abscess with aneurysms and spondylodiscitis as a complication of TRUS-guided prostate biopsy, and we review the relevant literature. CASE PRESENTATION: A 78-year-old man presented with back pain, sepsis, and prostate abscesses. Twenty days after TRUS-guided prostate biopsy, he was found to have a 20-mm diameter abdominal aortic aneurysm that expanded to 28.2 mm in the space of a week, despite antibiotic therapy. Therefore, he underwent transurethral resection of the prostate to control prostatic abscesses. Although his aneurysm decreased to 23 mm in size after surgery, he continued to experience back pain. He was diagnosed as having pyogenic spondylitis and this was managed using a lumbar corset. Sixty-four days after the prostate biopsy, the aneurysm had re-expanded to 30 mm; therefore, we performed endovascular aneurysm repair (EVAR) using a microcore stent graft 82 days after the biopsy. Four days after the EVAR, the patient developed acute cholecystitis, and he underwent endoscopic retrograde biliary drainage. One hundred and sixty days after the prostate biopsy, all the complications had improved, and he was discharged. A literature review identified a further six cases of spondylodiscitis that had occurred after transrectal ultrasound-guided prostate biopsy. CONCLUSIONS: We have reported the first case of a complication of TRUS-guided prostate biopsy that involved prostatic abscesses, aneurysms, and spondylodiscitis. Although such complications are uncommon, clinicians should be aware of the potential for such severe complications of this procedure to develop.

RESUMEN

BACKGROUND: Plasmacytoid urothelial carcinoma (PUC) of the urinary bladder is a variant of urothelial carcinoma that carries a poor prognosis. The epithelial-mesenchymal transition (EMT) has been demonstrated to contribute to tumor progression. As the cause of the increased aggressiveness of PUC is unknown, we investigated PUC and EMT-related marker expression. METHODS: A total of 633 bladder carcinoma cases diagnosed from 2006 to 2015 at the Nippon Medical School Hospital were analyzed. Twelve patients were found to have plasmacytoid histology and diagnosed with PUC. Slides were evaluated for percentage of plasmacytoid variant, and stained for E-cadherin, N-cadherin, Vimentin, Fibronectin and Snail expression. RESULTS: The incidence of PUC was 1.9% (12/633). The median patient age at diagnosis was 71 years (range, 60-80 years) and the male-female ratio was 11:1. All but three patients had stage T2b or higher. The median overall survival was 10 months. In 10/12 cases, Snail and N-cadherin were positive. Vimentin was positive in 9/12 cases. Fibronectin was positive in 8/12 cases. While E-cadherin was negative in 10/12 cases. Nine cases showed > 10% plasmacytoid component. Eight of the nine patients (88.9%) with > 10% plasmacytoid component died. CONCLUSIONS: The results indicate that PUC may induce EMT and may be associated with high invasion.

RESUMEN

PURPOSE: Bladder endometriosis (BE) is rare. Deep invasive endometriosis is difficult to control with medications alone; such cases need surgical treatment. Good results of laparoscopic partial cystectomy with a transurethral (TU) resectoscope by the see-through technique for patients with BE are reported. MATERIALS AND METHODS: From January 2008 to February 2016, 12 cases of symptomatic BE were seen in our institution. The chief complaints of 9 cases were micturition pain during menstruation. Preoperative cystoscopy showed a bladder mass with blueberry spots. All surgeries were performed under general anesthesia. Laparoscopic surgery was performed with a fan of 4 ports in the lower abdomen. First, the uterus and bilateral ovaries were checked. Then, the TU resectoscope was inserted. When the affected bladder wall was identified, it was again observed with the laparoscopic light source off, which made it possible to observe the twilight leaking inside from the bladder. This twilight came from the light source of the TU resectoscope via the unaffected bladder wall. In contrast, the thickness of the affected wall prevented the light from inside the bladder from passing through it. We call this the "see-through technique." The tumor was then safely dissected with both laparoscopic and TU resection procedures. Finally, the bladder was sutured by laparoscopic procedures using absorbable sterile surgical suture. The urethral catheter was removed after cystography 7 days after the operation. RESULTS: The surgical margins of all cases were negative. There has been no recurrence of BE so far in any patients. There were no major adverse events perioperatively and the urinary symptoms improved in all cases. CONCLUSIONS: By laparoscopic partial cystectomy assisted with a TU resectoscope and see-through technique, the edge of BE could be easily and precisely identified. These procedures are effective and safe for BE surgical treatment.

RESUMEN

We describe renal mucinous tubular and spindle cell carcinoma (MTSCC) that metastasized to the lymph nodes seven years after radical nephrectomy. An 80-year-old man was admitted for treatment of a right renal tumor. A 6.5×6.0-cm tumor in the right kidney (cT1bN0M0) revealed by abdominal computed tomography was treated by laparoscopic radical nephrectomy. The pathological findings at that time suggested papillary renal cell carcinoma type 1. Imaging findings seven years later revealed enlarged pre-caval and right external iliac lymph nodes indicative of delayed metastasis, and these were treated by laparoscopic lymphadenectomy. The pathological findings and re-evaluation of the primary tumor suggested MTSCC. The patient remains free of metastasis at 24 months of follow-up. MTSCC has been a distinct entity in the World Health Organization classification of kidney tumors since 2004. Tumors consist of tubules and cords separated by pale mucinous material in some areas, whereas others have dense cellularity without significant mucin. They are usually of low malignant potential, and metastasis has rarely been reported. To our knowledge, this is the first report of MTSCC with retroperitoneal lymph node metastasis treated by lymphadenectomy.

RESUMEN

BACKGROUND: To investigate associations between dual-specificity tyrosine phosphorylation-regulated kinase 2 (DYRK2) expression and survival in T1 high-grade or T2 bladder cancer patients treated with neoadjuvant chemotherapy. METHODS: The cohort under investigation comprised 44 patients who underwent neoadjuvant chemotherapy for pT1 high-grade or pT2N0M0 bladder cancer at our institution between 2002 and 2011. Immunohistochemical analysis was used to determine expression of DYRK2 in bladder cancer specimens obtained by transurethral resection before chemotherapy. Relationships between DYRK2 expression and both response to chemotherapy and survival in these patients were analyzed. RESULTS: DYRK2 expression was positive in 21 of 44 patients (47.7 %) and negative in 23 patients (52.3 %). In total, 20 of 21 DYRK2-positive cases showed complete response to neoadjuvant chemotherapy, whereas 11 of 23 DYRK2-negative cases did not show complete response. Sensitivity and specificity were 62.5 % and 91.7 %, respectively (P = 0.0018). In addition, disease-specific survival rate was significantly higher for DYRK2-positive patients than for DYRK2-negative patients (P = 0.017). In multivariate analysis, DYRK2 expression level was identified as an independent prognostic factor for disease-specific survival (P = 0.029). We also showed that DYRK2 mRNA expression was significantly higher in DYRK2-positive samples by immunohistochemistry than DYRK2-negative samples (P = 0.040). CONCLUSIONS: DYRK2 expression level may predict the efficacy of neoadjuvant chemotherapy for T1 high-grade and T2 bladder cancer.

RESUMEN

Vesicovaginal fistulas (VVFs) caused after radiation are difficult to repair and require interposition of non-irradiated, well-vascularized tissue between urinary bladder and vagina. A 48-year-old female suffered cervical cancer and underwent radical hysterectomy followed by radiation therapy which caused VVF. The initial surgical repair performed 3 months after development of VVF, was unsuccessful because of the absence of peritoneum or omentum to interpose between urinary bladder and vagina probably due to history of cesarean section and radical hysterectomy. The second surgical repair was performed 15 months after the first surgery utilizing a rectus abdominus myofascial (RAM) interposition flap. Fifteen months after the second operation, she remains free from incontinence. This case suggests that RAM is useful even for postradiation VVF.

RESUMEN

We report a case of retroperitoneal laparoscopic radical nephrectomy (LRN) in which the addition of a hand port was necessary and effective. A 52-year-old man with obesity (BMI 40.6 kg/m2) was diagnosed with a 52-mm left renal cell carcinoma (cT1bN0M0). To avoid thick subcutaneous and visceral fat in the abdomen, we selected LRN using a retroperitoneal approach with four ports in the kidney position. During surgery, a large amount of flank pad and perirenal fat prevented us from securing a sufficient surgical field through traction of the kidney with a retractor. A pure laparoscopic procedure was not feasible;therefore, we added a hand port. Subsequently, we removed the flank pad from the hand port and secured the surgical field by tracing the kidney manually. Finally, hand-assisted LRN was completed without an open conversion. In retroperitoneal LRN, we rarely encounter patients for whom a pure laparoscopic procedure is not feasible because of the large amount of flank pad or perirenal fat. It is important to preoperatively confirm not only the BMI but also the amount of flank pad and perirenal fat on imaging. Hand-assisted LRN via the retroperitoneal approach can be safely performed even in extremely obese patients. J. Med. Invest. 71 : 187-190, February, 2024.

RESUMEN

BACKGROUND: We present a case involving a pregnant woman who needed transurethral lithotripsy for ureteral stent removal because of the stent encrustation. CLINICAL CASE: A 34-year-old woman was diagnosed with calculous pyelonephritis, and a double-loop ureteral stent was placed in her right ureter, after which the pyelonephritis resolved. One week after her delivery, we attempted to remove the ureteral stent; however, the encrustation of the proximal and distal coils made it impossible. We then crushed the encrustation by transurethral lithotripsy and removed the ureteral stent successfully. The encrustation component was calcium phosphate, and the urinary pH during pregnancy and after delivery was 7.5. CONCLUSION: Even in pregnant patients, patients placed ureteral stents for obstructive pyelonephritis with high urine pH might need to be replaced in the short term due to concerns regarding phosphate encrustation.

RESUMEN

Introduction: A previous report has shown that cyclooxygenase-2 inhibitors can prevent the recurrence of cystitis glandularis postoperatively. Herein, we present a case of cystitis glandularis in which the tumor volume was markedly reduced by preoperative oral administration of a cyclooxygenase-2 inhibitor. Case presentation: A 45-year-old man with voiding difficulty and lower abdominal pain during urination was referred to our hospital. Cystoscopy revealed multiple cystitis glandularis-like edematous masses on the trigone and the neck of the bladder, completely involving the bilateral ureteral orifices. Cyclooxygenase-2 inhibitor was orally administered at the patient's request. Six weeks later, the tumor volume was markedly reduced, bilateral ureteral orifices were identified, and the voiding difficulty and pain on urination disappeared. Complete transurethral resection of the residual tumor was performed, and the pathological diagnosis was intestinal-type cystitis glandularis. Conclusion: Cyclooxygenase-2 inhibition can be considered a useful therapeutic strategy for cystitis glandularis.

RESUMEN

Introduction: We describe a case of an adrenal cavernous hemangioma that was surgically resected because of tumor growth and intratumoral hemorrhage. Case presentation: A 73-year-old woman presented with an enlarged adrenal tumor and intratumoral hemorrhage during the follow-up of an incidental adrenal tumor. A computed tomography showed that the left adrenal tumor had grown from 23 to 44 mm over 1 year. Blood tests revealed a normal metabolic profile. Paragangliomas and metastatic tumors were suspected on imaging. Laparoscopic adrenalectomy was performed to prevent tumor rupture due to further bleeding. No adhesions or bleeding were observed around the tumor during surgery. Pathological diagnosis was adrenal cavernous hemangioma. Conclusion: Adrenal cavernous hemangioma is difficult to distinguish preoperatively from other adrenal tumors, including malignant tumors. The intraoperative findings of this case suggest that laparoscopic adrenalectomy is a safe treatment option for relatively small adrenal cavernous hemangioma.

RESUMEN

Introduction: We encountered a case of urinary retention caused by a urethral caruncle. Case presentation: An 86-year-old woman presented to our hospital with urinary retention. When the urinary bladder catheter was placed, a smooth, well-defined mass 20 mm in diameter was detected on the posterior wall of the external urethral meatus. The patient was diagnosed with urinary retention due to a urethral caruncle, and the mass was resected. The mass was pathologically compatible with a urethral caruncle. The patient could urinate postoperatively. Ultrasound test after surgery showed residual urine volume was 100 mL. Conclusion: Inspecting the urethral meatus is vital in the clinical examination of older women with voiding symptoms. A urethral caruncle is a rare cause of urinary retention. However, large urethral caruncles are at risk of causing urinary retention suggesting that resecting the urethral caruncles at an appropriate time is desirable.

RESUMEN

BACKGROUND: This study aimed to investigate the preoperative risk factors for prolonged operating time in retroperitoneoscopic radical nephrectomy (RRN) for renal cell carcinoma (RCC). METHODS: We retrospectively reviewed patients treated for RRN between January 2015 and December 2021. Clinical data, including radiological findings such as visceral fat area (VFA), subcutaneous fat area (SFA), and posterior perirenal fat thickness (PFT) were collected. The operating time for RRN was analyzed using univariate and multivariate logistic regression analyses. RESULTS: A total of 79 patients were included. The median age was 66 (range: 28-88) years and 48 (60.8%) had right-sided tumors. The median tumor size was 52 (range: 12-100) mm. Median BMI, VFA, SFA, and posterior PFT were 22.9 (range: 16.3-42.2) kg/m2, 102 (range: 14-290) cm2, 124 (range: 33-530) cm2, and 6 (range: 1-35) mm. The median operating time was 248 (range: 140-458) min. Univariate logistic regression analyses revealed that a right tumor (p=0.046), tumor size >7 cm (p=0.010), and posterior PFT >25 mm (p=0.006) were preoperative risk factors for prolonged operating time in RRN. Multivariate logistic regression analyses revealed that a posterior PFT of >25 mm was an independent preoperative risk factor for prolonged operating time for RRN (p=0.008, OR: 7.29, 95% CI: 1.69-31.5). CONCLUSIONS: A posterior PFT >25 mm was an independent preoperative risk factor for the operating time of RRN. In RRN, for patients with a posterior PFT >25 mm, surgeons should develop surgical strategies, including the selection of a transperitoneal approach to surgery, to avoid prolonging the operating time.

RESUMEN

Background: Epididymal injuries without ipsilateral injuries of the testicles are rare. We report a case of a solitary right epididymal injury complicated by left testicular rupture. Case Presentation: A 21-year-old man experienced scrotal trauma caused by a motorcycle accident. Bilateral swelling and tenderness of the scrotum were observed. Ultrasonography and computed tomography revealed a ruptured left testicle; therefore, surgery was performed. During surgery, the left testicle was excised because it was completely ruptured, and the right testicle and epididymis were evaluated to identify the cause of swelling of the right scrotum. The right testis was not injured; however, the right epididymis was lacerated. Subsequently, the lacerated right epididymis was repaired using sutures. A semen analysis performed at 1, 4, and 7 months after surgery revealed the absence of sperm in the semen. Conclusion: Epididymal injuries should be considered as differential diagnoses for scrotal trauma.

RESUMEN

Introduction: We present the case of a rapidly growing inferior vena cava tumor thrombus in renal cell carcinoma. Case presentation: We present a case of a 66-year-old woman with right renal cell carcinoma with a tumor thrombus extending 2 cm into the inferior vena cava on an initial Imaging. Radical surgery was performed 6 weeks after the first visit. Intraoperatively, the tumor thrombus was confirmed to have grown near the diaphragm. The tumor was resected using an inferior vena cava clamping just below the diaphragm. The tumor thrombus and renal cell carcinoma were completely removed. There was no recurrence 6 months postoperatively. Conclusion: Inferior vena cava tumor thrombus in renal cell carcinoma can grow in a short period, suggesting that preoperative imaging evaluation at the appropriate time is important. Once inferior vena cava tumor thrombus of renal cell carcinoma occurs, surgery should not be delayed unless there is an urgent reason.

RESUMEN

BACKGROUND: Neoadjuvant chemotherapy has been shown to have benefit in T1 high-grade or T2 bladder cancer. However, neoadjuvant chemotherapy fails in some patients. Careful patient selection for neoadjuvant chemotherapy is therefore needed. Several reports show that Snail is associated with resistance to chemotherapy. We hypothesized that Snail expression could predict survival in T1 high-grade and T2 bladder cancer patients treated with neoadjuvant chemotherapy. METHODS: The participants were 44 patients with T1 high-grade and T2 bladder cancer receiving neoadjuvant chemotherapy. Immunohistochemical analysis was used to determine Snail expression in specimens of bladder cancer obtained by transurethral resection before neoadjuvant chemotherapy. The relationships between Snail expression and patients' outcomes were analyzed. RESULTS: Snail expression was positive in 15 of the 44 patients (34.1%) and negative in 29 (65.9%). Disease-free survival was significantly shorter for the Snail-positive group than for the Snail-negative group (p = 0.014). In addition, disease-specific survival was also significantly shorter for the Snail-positive group than for the Snail-negative group (p = 0.039). In multivariate analysis, Snail expression level was identified as an independent prognostic factor for disease-specific survival (p = 0.020). CONCLUSIONS: The results indicate that Snail expression may predict poor outcome in T1 high-grade and T2 bladder cancer patients treated with neoadjuvant chemotherapy.

RESUMEN

We reported the experience with a case of plasmacytoid variant of urothelial carcinoma of urinary bladder. A 75-year-old woman complained of gross hematuria. She was hospitalized to be diagnosed as the bladder tumor on abdominal CT. TUR-BT was performed and pathological finding was invasive urothelial carcinoma. But she refused radical cystectomy. 2 months later, she was hospitalized again with worsening hematuria. Simple cystectomy was performed. Histological examination revealed a plasmacytoid appearance of the infiltrating tumor cells. Immunohistochemical stains for lymphoid markers were negative. Those findings lead to the diagnosis of plasmacytoid variant of urothelial carcinoma. She died due to local recurrence for 1.5 months after simple cystectomy.
