Evolving horizons in renal angiomyolipoma: two decades of management strategies and clinical perspectives in a single institutional study.

OBJECTIVE: To assess various management options for renal angiomyolipoma (AML) to guide clinical practice. METHODS: A single center retrospectively reviewed an AML series from 2002 to 2022. The image reports and chart reviews of patients who received two abdominal scans at least 6 months between the first and last scans were assessed. RESULTS: A total of 203 patients with 209 tumors were identified and followed up for a median of 42.6 months. Active surveillance (AS) was the most frequently selected option (70.9% of cases). Interventions were required for 59 AMLs, of which 20 were treated with embolization, 29 with partial nephrectomy, 9 with radical nephrectomy, and 1 with radiofrequency (RF) ablation. The median size of the lesions at intervention was 5 cm. The average growth rate of the lesions was 0.12 cm/year, and there was a significant difference in the average growth rate of lesions ≤4 cm and those >4 cm (0.11 vs. 0.24 cm/year; p = 0.0046). CONCLUSION: This series on AMLs confirms that lesions >4 cm do not require early intervention based on size alone. Appropriately selected cases of renal AML can be managed by AS.KEYWORDS: Angiomyolipoma; active surveillance; embolization; nephrectomy; nephron-sparing surgery.

Impact of health and digital health literacy on quality of life following radical prostatectomy for prostate cancer: prospective single-center cohort study.

PURPOSE: The importance of health literacy (HL) and digital health literacy (e-HL) in promoting healthy behavior and informed decision making is becoming increasingly apparent. This study aimed to assess the effects of HL and e-HL on the quality of life (QoL) of men who underwent radical prostatectomy (RP) for localized prostate cancer. MATERIALS AND METHODS: This prospective observational study included 104 patients who underwent RP for localized prostate cancer. HL and e-HL were evaluated using the validated eHealth Literacy Scale and European Health Literacy Survey Questionnaire Short Form before RP. We evaluated patients' physical, psychological, social, and global QoL using the validated EORTC QLQ-C30 8 weeks after RP. The exclusion criterion was any difficulties in language and comprehension. We employed one-way ANOVA to compare continuous variables across groups in univariate analysis and used MANOVA for exploring relationships among multiple continuous variables and groups in the multivariate analysis. RESULTS: Multivariate analyses showed that poorer e-HL and HL were associated with being older (p = 0.019), having less education (p < 0.001), and not having access to the internet (p < 0.001). Logistic regression analysis revealed significant associations between improved e-HL (p = 0.043) and HL (p = 0.023), better global health status, and higher emotional functioning (p = 0.011). However, the symptom scales did not differ significantly between the e-HL and HL groups. CONCLUSION: Our study showed a positive association between self-reported HL/e-HL and QoL, marking the first report on the impact of HL/e-HL on the QoL in men who underwent RP for clinically localized prostate cancer.

Paratesticular Dedifferentiated Liposarcoma with Rhabdomyoblastic Differentiation: A Case Report and Review of the Literature.

Liposarcomas of the paratesticular tissue is a rare pathological entity. The symptoms are similar to inguinal hernias or hydroceles. We present the case of an 84-year-old man with a rare paratesticular liposarcoma that manifested as painless right hemiscrotal swelling. Testicular tumour markers were negative. Imaging revealed a heterogeneous mass with a fat component. He underwent a radical orchiectomy on the left side to remove the associated mass. This revealed dedifferentiated liposarcoma (DDLS) with rhabdomyoblastic differentiation and MDM2 amplification. The surgical margins were negative, and the patient had a metastatic workup that included magnetic resonance imaging (MRI) of the abdomen and pelvis. Because of the disease's rarity, there is no clear agreement on radiotherapy and chemotherapy roles.

A comparison of pre- and post-operative outcomes in living donors undergoing transperitoneal laparoscopic nephrectomy and open nephrectomy: a retrospective single-center study.

BACKGROUND: Kidney transplantation is often regarded as the preferred therapy for end-stage renal disease. Several surgical procedures have been developed to reduce postoperative donor complications, while maintaining kidney quality. OBJECTIVE: This study aimed to compare the preoperative and postoperative outcomes of living kidney donors who underwent either transperitoneal laparoscopic nephrectomy or open nephrectomy. DESIGN AND SETTING: Retrospective study conducted in Istanbul, Turkey. METHODS: Fifty-five living-related kidney donors underwent nephrectomy and were retrospectively divided into two groups: 21 donors who underwent open nephrectomy (Group 1) and 34 donors who underwent transperitoneal laparoscopic nephrectomy (Group 2). RESULTS: In comparison to the donors who underwent open nephrectomy, those who underwent transperitoneal laparoscopic nephrectomy had significantly shorter postoperative hospital stays (2.3 ± 0.2 versus 3.8 ± 0.8 days, P = 0.003), duration of urinary catheterization (1.2 ± 0.8 days versus 2.0 ± 0.7 days, P = 0.0001), operating times (210 ± 27 minutes versus 185 ± 24 minutes, P = 0.02), and less blood loss (86 ml versus 142 ml, P = 0.048). There was no statistically significant difference between the two groups with regard to the estimated blood transfusion and warm ischemia time. The preoperative week, first postoperative week, and 1-month postoperative serum creatinine levels were comparable between the groups. CONCLUSIONS: Laparoscopic donor nephrectomy can be safely performed at centers with expertise in laparoscopic surgery. Laparoscopic donor nephrectomy has better outcomes than open donor nephrectomy in terms of length of hospital stay, duration of urinary catheterization, operating time, and blood loss.

Assessment of redox homeostasis via genotoxicity, cytotoxicity, apoptosis and NRF-2 in colorectal cancer cell lines after treatment with Ganoderma lucidum extract.

This study aimed to investigate the cytotoxic and apoptotic effects of Ganoderma lucidum, Pleurotus ostreatus, Pleurotus eryngii, and Inonotus hispidus fungal extracts on HT-29 and HCT-116 colorectal cancer cell lines and to search the DNA damage and oxidative stress caused by these extracts. Accordingly, mushroom extracts were applied to colorectal cancer cell lines in vitro, and the IC50 result was obtained with the MTT test. According to the IC50 result, Ganoderma lucidum extract had the most effective cytotoxicity value among all used mushroom extracts. TAS, TOS, and NRF-2 tests were used to investigate the molecular effect of Ganoderma lucidum extract on oxidative stress; the DNA ladder test was performed to assess DNA damage, the Scratch assay method was applied for cell migration analysis, and the colony assay was used to determine the colony formation potential of the cells. The results showed that Ganoderma lucidum mushroom extract reduces cell proliferation, colony formation, and NRF-2, induces DNA damage, slows cell migration, and increases oxidative stress. This study shows that Ganoderma lucidum mushroom extract reduces cell proliferation through damaging cellular DNA and has a cytotoxic effect in colorectal cancer cell lines.

The Role of Educational Level and Cognitive Status in Men Undergoing Artificial Urinary Sphincter Implantation.

OBJECTIVE: To examine the relationship between education level, cognitive function of patients and the success/ revision rates of artificial urinary sphincter (AUS) implantation in men with postprostatectomy incontinence. METHODS: Between January 2010 and March 2018, 163 patients (mean age, 68 ± 6.8 years) with moderate-to-severe stress urinary incontinence who underwent AUS implantation were retrospectively examined. Demographic data, body mass index, comorbidities, surgical technique, previous strictures, and radiation therapy were recorded. Incontinence was measured by daily pad use and evaluated by International Consultation on Incontinence Questionnaire-short form. Patients' overall improvement was assessed using the Patient Global Impression of Improvement questionnaire. Education level was determined using the International Standard Classification of Education. Cognitive status was assessed using the Mini-Mental State Examination. Treatment success was defined as the need for ≤1 pad/day at last follow-up. RESULTS: AUS was successful in 77.3% of patients. The International Consultation on Incontinence Questionnaire-short form score improved significantly from 19.9 ± 2.9 to 4.4 ± 5.4 (P = .001). The median outcome reported subjectively on the Patient Global Impression of Improvement scale was 2.1 ± 1.5 (1-7) and self-reported as "much better." Patients' education level had statistically no significant relationship with AUS success and revision rates. Similarly, there was no significant relationship between cognitive status, educational level and the need for revision of AUS (P >.05). However, patients with moderate cognitive impairment and a body mass index >30 showed significantly lower AUS success rates (P <.05). CONCLUSION: AUS implantation is safe and effective treatment option especially for nonobese and cognitively intact patients of all educational levels.

Investigation of the Effectiveness of Surgical Treatment on Respiratory Functions in Patients With Obstructive Sleep Apnea Syndrome.

OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) is a problem that involves many bodily systems and its effects on the respiratory system deserve special attention. Although many studies exist that investigate respiratory functions in patients using continuous positive airway pressure (CPAP) for the treatment of sleep apnea, there is a lack of research regarding the effect of OSAS surgery on respiratory function in the literature, which has motivated us to perform such a study. MATERIALS AND METHODS: Thirty-two patients diagnosed with OSAS with an apnea hypopnea index ranging between 15 and 30 and had undergone robotic tongue base resection and uvulopharyngoplasty were included as study participants. Pulmonary function tests were performed on all participants 1 day prior to, and at 3 and 6 months after the operation. Weight and body mass indices (BMIs) were also recorded at the same intervals for all participants. Data were electronically recorded and analyzed through SPSS 22.0. Values of P < .05 have been considered as statistically significant. RESULTS: Average age of the 32 participants was 43.2±10.7, average body weight was 94.1±12.6, and average BMI was 31.4±4.7. Decreases in body weight and BMI values recorded at 3 and 6 months postoperatively had statistical significance when compared with values recorded preoperatively (P < .05). Comparisons made in terms of pulmonary functions revealed a statistically significant increase in 3 and 6-month postoperative values of FVC, FEV1, FEV1/FVC, PEF, and FEF 25-75 (P < .05). CONCLUSION: Our study shows the positive effects of robotic tongue base resection and uvulopharyngoplasty operation on respiratory function parameters. This suggests that surgical treatment in OSAS patients is as effective as CPAP on respiratory function.

Single-incision midurethral sling shows less pain and similar success rate in a short-term follow-up compared to the transobturator tape method in the treatment of stress urinary incontinence.

OBJECTIVE: To compare the efficacy, complications, quality of life, and patient satisfaction rates in women treated for stress urinary incontinence (SUI) using the adjustable anchored single-incision midurethral sling (SIMS) and standard midurethral sling (MUS) procedures. MATERIAL AND METHODS: A total of 113 women between October 2012 and October 2016 underwent either the adjustable SIMS (n=54) or MUS (n=57) procedure. The postoperative pain profile was assessed using a 10-point visual analog scale at the fixed time-point quality of life and an additional postoperative 3rd week appointment. We asked our patients the following two questions to evaluate their satisfaction with surgery and their preference: "Would you have this kind of surgery again?" (Q1), and "Would you recommend this type of surgery to another patient with same symptoms?" (Q2). For the evaluation of patient complaints, the Incontinence Impact Questionnaire (IIQ-7) and Urinary Distress Inventory (UDI-6) were used before and after the procedure. RESULTS: Women in the SIMS group had a significantly lower postoperative pain profile for up to 3 weeks (p<0.001). There was no significant difference in perioperative complications and postoperative continence rates between the groups. With regard to Q1 and Q2, a significant difference was found between the groups (p=0.003 and p=0.002, respectively). While the questionnaire scores of the IIQ-7 and UDI-6 were also significantly improved at postoperative evaluations (p<0.001), there was no significant difference between the two groups. CONCLUSION: SIMS is associated with a significantly improved postoperative pain profile and earlier return to work when compared to MUS.

Do success rate, complications of transobturator tape procedure differ based on experienced surgeon or residents? / ¿Son diferentes las tasas de éxito y complicaciones de la malla transobturatriz entre cirujanos expertos y residentes?

OBJECTIVES: To investigate the postoperative surgical complications and patient satisfaction with the outside-in transobturator tape (TOT) procedure performed by an experienced surgeon compared to those performed by residents in training. METHODS: Patients who received TOT surgery performed by a resident under supervision of a faculty were included in group 1 (n = 31) whereas, patients operated by the same faculty were included in group 2 (n = 26). Both groups were compared for demographic data, procedure results, satisfaction rates as well as intraoperative and early postoperative (urinary retention, vaginal erosion, dyspareunia, infection, abnormal discharge) complications. Statistical Package for Social Sciences for Windows was used for statistical analyses. For continuous variables Mann-Whitney U test and for categorical variables Chi-square, Fishers exact tests were used. RESULTS: Stress incontinence in groups 1 and 2 were either completely cured or improved in 87.1% and 84.6%, respectively. The question" Would you like to have an operation like this again?" was answered positively by 26 (83.9%) of patients in group 1 and by 22 (84.6%) in group 2. There was no significant difference between two groups for the complication rates occurred within 90-days period. However, there was a significantly higher groin pain persisting more than three weeks in group 1 (38.7%) compared to group 2 patients (7.7%). CONCLUSIONS: There was statistically significant increased groin pain in the early period in TOT procedures performed by the residents. However, the complications observed in both groups did not affect the success rate or patient satisfaction.

OBJETIVOS: Investigar las complicaciones quirúrgicas postoperatorias y la satisfacción del paciente con la operacion de malla transonbturatriz fuera-adentro realizada por un cirujano experto en comparación con la realizada por residentes en formación.MÉTODOS: Las pacientes operadas de TOT por un residente bajo supervisión de un adjunto se incluyeron en el grupo 1 (n = 31) y las operadas por el mismo adjunto se incluyeron en el grupo 2 (n = 26). Se compararon los datos demográficos, resultados de la operación, tasas de satisfacción así como las complicaciones intraoperatorias y postoperatorias tempranas (retención urinaria, erosión vaginal, dispareumia, infeccion, flujo anormal). Para el análisis estadístico se utilizó el software SPSS para Windows. Se utilizaron el test de la U de Mann- Whitney para variables continuas y los de Chi cuadrado y Prueba exacta de Fisher para variables categóricas. RESULTADOS: La incontinencia urinaria de esfuerzo en los grupos 1 y 2 fue bien completamente curada, bien mejoró en 87,1% y 84,6%, respectivamente. La pregunta ¿volvería a someterse a la misma operación? fue respondida positivamente por 26 (83,9%) de los pacientes en el grupo 1 y 22 (84,6%) en el grupo 2. No había diferencias estadísticamente significativas entre los grupos en la tasa de complicaciones en los primeros 90 días. Sin embargo, el dolor en la ingle que persistía más de 3 semanas era significativamente mayor en el grupo 1 (38,7%) en comparación con las pacientes del grupo 2 (7,7%). CONCLUSIONES: Hay un aumento estadisticamente significativo del dolor en el muslo en el periodo postoperatorio temprano de las operaciones de TOT realizadas por residentes. Sin embargo, las complicaciones observadas en ambos grupos no afectaron a la tasa de éxitos o a la satisfaccion del paciente.

Postoperative outcomes of plasmakinetic transurethral resection of the prostate compared to monopolar transurethral resection of the prostate in patients with comorbidities.

OBJECTIVE: To compare the 12-month postoperative clinical data in patients with comorbidities undergoing plasmakinetic enucleation of the prostate (PK-TURP) and monopolar transurethral resection of the prostate (M-TURP) for symptomatic benign prostatic hyperplasia (BPH). METHODS: The data of 165 patients undergoing either PK-TURP or M-TURP from September 2006 to December 2010 were retrospectively evaluated in terms of erectile function. Decrease in Hb level at 24-hour follow-up, variations in serum Na(+) at 2-hour follow-up, and 12 month postoperative International Prostate Symptom Score (IPSS), Q(max.), postoperative International Index of Erectile Function (IIEF) scores and urethral stricture rates were evaluated. RESULTS: A total of 85 patients underwent M-TURP and 80 patients PK-TURP. In all, 62 patients in M-TURP group and 71 patients in PK-TURP group had one or more comorbidities (P = .01). The operative times were 59.8 ± 17.8 versus 60.3 ± 23.8 (P = 0.539). The postoperative 12-month IIEF scores of PK-TURP patients were significantly higher than those of M-TURP patients (M-TURP; 14.5 ± 6.9, PK-TURP; 17.4 ± 8.9, P = .04). IPSS and Q(max.) were similar in both the M-TURP and PK-TURP treatment arms (10.9 ± 8.1 versus 9 ± 7.9, P = .187 and 18.9 ± 4.8 versus 18.8 ± 6.4, P = .905). Urethral stricture rate was 3/62 in M-TURP versus 8/71 in PK-TURP treatment arm, P = .171). CONCLUSION: Both modalities yielded similar results with respect to IPSS and Q(max.). The postoperative IIEF in BPH patients with comorbidities appeared to be significantly higher in the PK-TURP group. Although urethral stricture rates seemed higher in the PK-TURP arm, the difference was not statistically significant.

Inhibition of tooth movement by osteoprotegerin vs. pamidronate under conditions of constant orthodontic force.

The undesired movement of anchor teeth, and relapse of previously moved teeth, are major clinical problems in orthodontics. Dental implants are increasingly used to preserve anchorage, but these are costly and require invasive surgical procedures. An alternative strategy for maintaining anchorage may be the use of biological inhibitors of osteoclastic bone resorption. In the present study, we investigated the relative efficacy of pamidronate vs. osteoprotegerin (OPG) in inhibiting bone resorption and tooth movement, using a new orthodontic model in mice in which maxillary molars are moved for prolonged periods by near-constant, clinically relevant forces. Osteoclast influx to compression sites was initiated on day 3, was maximal on day 4, and persisted until at least day 12 after force application. Tooth movement paralleled osteoclast numbers. Minimal osteoclast apoptosis was observed, suggesting that recruitment, rather than programmed cell death, is a critical regulatory mechanism under conditions of constant force. Osteoclasts were reduced at compression sites by both OPG (95%) and pamidronate (70%); tooth movement was more dramatically inhibited by OPG (77% vs. 34%). Our findings indicate that constant orthodontic force regulates the recruitment, activation, and viability of osteoclasts, and that OPG could have clinical utility in preventing undesired tooth movement.
