BACKGROUND: Cryopreservation of immature testicular tissue could be considered as a major step in fertility preservation for young boys with cancer. In the present study, eight different freezing protocols were evaluated in immature mice testis. METHODS: Testis from six-day-old mice were frozen using either 1,2-propanediol (PROH) or dimethylsulphoxide (DMSO: D) at 1.5 M. Different cooling rate curves were tested: (i) controlled slow protocol with seeding (CS1) or (ii) without seeding (CS2), (iii) controlled rapid protocol and (iv) non-controlled protocol. Cryodamage of seminiferous cords was semi-quantitatively determined, establishing a scoring of alterations. Cell viability and apoptosis induction were assessed on testicular cell suspensions immediately after digestion (D0) and after a 20-h culture period (D1). Cells recovered after digestion of 100 mg tissue and the rate of living and non-apoptotic cells were quantified at D0 and D1. A long-term culture (9 days) of testis pieces was carried out for the protocol offering the best survival. Testosterone production, intratubular cell proliferation and tubule growth were assessed. RESULTS: DMSO produced optimal results in the different cooling rate curves tested when compared with PROH. Optimal results were obtained for the DCS2 procedure (P < 0.05). Testosterone production, tubule growth and cell proliferation of post-thaw pieces were similar to fresh samples. CONCLUSIONS: Testis freezing with 1.5 M DMSO in a CS2 procedure was found to maintain not only immature testicular tissue architecture, but also viability of testicular cells, endocrine and partial exocrine functions of the testis. Semi-quantitative evaluation of seminiferous cord cryodamage can be effectively used to rapidly screen optimal freezing conditions and as a possible quality control in a human application.
OBJECTIVES
To compare results of prostate laser photovaporization (PVP) by age groups to evaluate morbidity and functional results. Then, to specifically analyze surgical data for patients with an indwelling bladder catheter.
DESIGN
Monocentric retrospective study of a prospective maintained database of all laser PVPs performed at our university hospital between December 2012 and June 2017.
SETTINGS AND PARTICIPANTS
A total of 305 patients (three groups: younger than 70, 70‐80, and older than 80 years) were operated on in our hospital center for the treatment of urinary tract disorders related to benign prostatic hyperplasia.
RESULTS
A difference was found between the three age groups, with a higher rate of complications for patients older than 80 years (45%) (P = .013). Rate of patients with postoperative bladder catheters at 1 year was higher for patients older than 80 years (15%) (P = .004). Postoperative quality‐of‐life (QoL) score was worse for patients older than 80 years (P = .04).
For patients with an indwelling bladder catheter undergoing surgery, morbidity was greater in patients older than 80 years, but the difference was not significant. International Prostate Symptom Score and QoL score were not significantly different between the three groups.
Rate of patients with a remaining bladder catheter at 1 year was higher for patients older than 80 years (17.1% vs 7.1% for patients between 70 and 80, and 4.8% for patients under 70.) but with no statistical difference.
CONCLUSION
PVP had a greater morbidity in octogenarians compared to younger subjects. Functional results were less satisfactory for patients older than 80 years compared to younger ones. For subjects operated on with an indwelling bladder catheter, no significant difference in outcome and morbidity was found between the three groups. J Am Geriatr Soc 67:1888–1894, 2019
If single adrenal metastasis surgery is well admitted, no recommendation exists about the management of a renal vein tumor thrombus, even though the actual consensual attitude consists in a nephrectomy associated to an adrenalectomy. We report, here, the case of a 74-year-old man with a suspected adrenal metastasis of a lung carcinoma associated with a left adrenal and renal vein tumor thrombus treated by adrenalectomy and renal vein thrombectomy and ipsilateral kidney sparing. The postoperative computed tomography scan showed no thrombus in the left renal vein. Doppler ultrasound performed 1 month after adrenalectomy proved a good left renal vein flux. At 36 months of follow-up, the patient is alive without signs of recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
