Prognostic significance of tumor budding in muscle invasive urothelial carcinomas of the bladder

WOS: 000474443200007PubMed ID: 30183610Objective: The aim of this study was to evaluate the prognostic significance of tumor budding in muscle invasive urothelial carcinoma of bladder (MIBC). Material and methods: A total of 60 patients who underwent radical cystectomy and cystoprostatectomy for MIBC were included in the study. The correlations between tumor budding, and tumor necrosis, lymphovascular invasion (LVI), perineural invasion (PNI) and histopathological data with distant metastasis were evaluated. The correlation between progression free (PFS) and overall survival (OS) rates and the presence, and grade of tumor budding was investigated. Results: A statistically significant correlation was not seen between tumor budding, necrosis, LVI, and PNI. There was a strong correlation between distant organ metastasis, and presence of tumor necrosis. There was no statistically significant correlation between PFS, OS and tumor budding. A statistically significant relationship was observed between OS and tumor stage, lymph node metastasis, and distant organ metastasis. Conclusion: In our study, statistically significant effect of tumor budding on survival rates in MIBCs was not observed. Also, no significant correlation was observed between tumor budding and tumor necrosis, LVI, and PNI

Is Prostate Biopsy Recommended in Turkish Men with a Prostate-Specific Antigen Level between 2.5 and 4 ng/mL?

Background: Prostate cancer is the most common solid tumor. The incidence of prostate cancer shows regional and racial differences. The ideal PSA threshold for prostate biopsy is still being debated. Objective: We aimed to investigate cancer detection rates in Turkish men who underwent transrectal ultrasound-guided prostate biopsy (TRUSPB) who had prostate-specific antigen (PSA) levels in the range of 2.5 to 4.0 ng/mL and compare them with the rates of cancer in patients with PSA levels in the range of 4.0 to 10.0 ng/mL. Methods: All Turkish men who underwent TRUSPB in our clinic between January 2012 and May 2014 were included; that is, 101 patients (Group 1) with PSA level in the range of 2.5 to 4.0 ng/mL and 522 patients (Group 2) with PSA level in the range of 4.0 to 10.0 ng/mL. Mean PSA level, age, prostate volume, and cancer detection rates were evaluated. Results: The mean age was 60.5 and 64 years in Group 1 and Group 2, respectively (P = 0.06). The mean PSA level was determined as 3.1 and 6.8 ng/mL in Group 1 and Group 2, respectively (P = 0.03). The cancer detection rate was 12.7% in Group 1 (n = 13) and 30.8% in Group 2 (n = 161), which revealed a statistically significant difference between the 2 groups (P = 0.001). In Group 1, 9 of 13 patients (69%) had Gleason score of 6, 3 (23%) had Gleason score of 7, and 1 (8%) had a Gleason score of 8. Conclusions: The cancer detection rate is lower in Turkish men with PSA level in the range of 2.5 to 4.0 ng/mL when compared with men with PSA level in the range of 4.0 to 10.0 ng/mL. Furthermore, most patients in whom cancer was detected who have a PSA level in the range of 2.5 to 4.0 ng/mL are low risk. Therefore, the benefit of TRUSBP in Turkish men with PSA level between 2.5 and 4 ng/mL is low

Continuous positive airway pressure therapy is associated with improvement in overactive bladder symptoms in women with obstructive sleep apnea syndrome

Introduction To evaluate the impact of continuous positive airway pressure (CPAP) therapy on overactive bladder (OAB) symptoms in women with obstructive sleep apnea syndrome (OSAS). Material and methods One-hundred and fifty women underwent an overnight polysomnography study between May 2014 and September 2014. Their voiding symptoms were evaluated using the OAB symptom score (OABSS) and International Consultation on Incontinence Questionnaire Short-Form at OSAS diagnosis and approximately 3-months after CPAP therapy. OSAS severity was assessed according to the apnea-hypopnea-index. Results We evaluated 140 women and 111 of them (79.3%) reported symptoms consistent with OAB. There were no statistically significant differences between OSAS severity with a prevalence of OAB (p = 0.92). The prevalence of urinary incontinence (UI) was 35.7% (n = 50) and 39.6% (n = 44) in all patients and patients with OAB, respectively. There were no statistically significant differences between UI with OAB (p = 0.58). Baseline OABSS is comparable between OSAS severity (p = 0.143). After 3-months CPAP therapy, OABSS and ICIQ-SF sum scores were significantly decreased in patients with severe and moderate OSAS (p < 0.01), however, change of OABSS sum score was insignificant in patients with mild OSAS (p = 0.44). Conclusions CPAP therapy improves the OAB, OABSS and ICIQ-SF scores in women with severe and moderate OSAS. OSAS-induced OAB may be alleviated following CPAP therapy

Current approach for urinary system stone disease in pregnant women

Urinary system stones can be classified according to size, location, X-ray characteristics, aetiology of formation, composition, and risk of recurrence. Especially urolithiasis during pregnancy is a diagnostic and therapeutic challenge. In most cases, it becomes symptomatic in the second or third trimester. Diagnostic options in pregnant women are limited due to the possible teratogenic, carcinogenic, and mutagenic risk of foetal radiation exposure. Clinical management of a pregnant urolithiasis patient is complex and demands close collaboration between patient, obstetrician and urologist. We would like to review current diagnosis and treatment modalities of stone disease of pregnant woman

Comparison of intraperitoneal and intratesticular ozone therapy for the treatment of testicular ischemia-reperfusion injury in rats

We compare the efficacy of intratesticular ozone therapy with intraperitoneal ozone therapy in an experimental rat model. For this purpose, 24 rats were divided into four groups including sham-operated, torsion/detorsion, torsion/detorsion plus intraperitoneal ozone (O-IP), and torsion/detorsion plus intratesticular ozone (O-IT). The O-IP ozone group received a 4 mg kg−1 intraperitoneal injection of ozone, and the O-IT group received the same injection epididymally. At 4 h after detorsion, the rats were sacrificed and orchiectomy materials were assessed histopathologically. Spermatogenesis in the seminiferous tubules and damage to the Sertoli cells were histopathologically evaluated in the testes using the Johnsen scoring system. i-NOS and e-NOS activities in the testis tissue were also evaluated. Torsion-detorsion caused a decreased Johnsen score and increased apoptosis of spermatogonial and Sertoli cells. Ozone injection prevented increases in Johnsen score and i-NOS level. e-NOS level of the O-IP group was significantly lower than that of the O-IP group, and i-NOS level of the O-IT group was significantly lower than that of the O-IP group. Local ozone therapy is more effective than systemic ozone therapy at improving IRI-related testicular torsion. Our study is the first to show that the efficacy of intratesticular implementation of ozone therapy is higher than that of intraperitoneal ozone therapy

A rare complication after renal transplantation: Forgotten stent

In renal transplantation surgery, double J stents (DJS) are often used to reduce complications, protect the anastomosis between ureter and bladder, provide drainage in ureteral obstructions and enhance healing if there is an ureter injury. Urinary tract infections, hematuria and irritative voiding symptoms are the early complications of DJS. Migration, fragmantation, encrustation and rarely sepsis are among the late complications of DJS. In this report we describe a renal transplantation case whose DJS stent was forgotten because the patient did not attend the regular follow-up and noticed 5 years after surgery
