Delay to Inguinal Lymph Node Dissection Greater than 3 months Predicts Poorer Recurrence Free Survival for Penile Cancer Patients
It is unknown if concomitant inguinal lymph node dissection (ILND) at time of penectomy improves outcomes for penile cancer patients. We analyzed predictors for regional recurrence as well as recurrence free (RFS) and disease specific (DSS) survival based on time of ILND, and determine an optimal time for performance of ILND.
It is difficult for many of us to comprehend that we have been flying in space for over 50 years, and except for a one-year gap between the Russian Mir Station and the International Space Stations (ISS), most of the past 28 years have seen a continual human presence in low Earth orbit. Aside from the risks associated with leaving the planet and the remoteness of spacecraft, human health and performance in space is dominated by the condition of weightlessness. The removal of the gravity-driven hydrostatic gradient along with predictable anthropomorphic changes drives a set of global adaptive responses in nearly every physiologic system.

In this issue of Urology, the Soria et al report an intriguing study describing late recurrences following radical cystectomy (RC) for bladder cancer.1 A total of 1652 mostly muscle-invasive bladder cancer (MIBC) patients undergoing RC were evaluated in this large, multicenter, retrospective study. Of these, 548 (33.2%) patients recurred with a median time to recurrence of 1 year. Late recurrences defined as those occurring >5 years after RC occurred in 67 patients, i.e. 12.2% of recurrences and 4.1% of all patients who underwent RC.

Childhood voiding dysfunction or bowel-bladder dysfunction in the absence of an underlying neurological condition is characterized by a heterogeneous collection of symptoms, including fecal and urinary frequency/urgency and incontinence, urinary retention and chronic constipation. Historically treatment options have included behavioral modification (timed voiding, biofeedback), oral pharmacological agents (alpha blockers, anticholinergics, stool softeners) and surgical intervention for patients with severe/refractory dysfunction.
Surgical treatments for pelvic organ prolapse (POP) and stress urinary incontinence (SUI) using transvaginal mesh kits have provoked debates, controversies, strong opinions and class action liability lawsuits against mesh kit manufacturers. While the use of transvaginal mesh for POP reconstruction has waned considerably, using mesh slings (via the midurethral retropubic and midurethral transobturator approaches) for SUI remains popular. AUGS (American Urogynecologic Society) and SUFU (Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction) issued a joint position statement in January 2014 supporting midurethral mesh slings as the gold standard for surgical treatment of SUI.
We absolutely agree that Ho:YAG lithotripsy is most efficient when stones are targeted directly with the laser fiber. Nevertheless the presence of multiple calyceal stones often presents a particular challenge, especially with hard stones such as CaOx monohydrate. Direct fragmentation will produce fragments exponentially. Targeting each stone separately may not always be easy due to kidney movement or retropulsion at high energy and short pulse fragmentation settings (reference 10 in article). Also, fragmentation and extraction may be time-consuming.
The Ho:YAG laser works by a photothermal mechanism that involves direct absorption of photons on the stone surface.1 Ho:YAG lithotripsy is most efficient when the stone is in a fixed position and the stone surface is targeted in contact mode with the laser fiber oriented to the stone surface at a normal incidence (references 2 and 13 in article).1 Occasionally circumstances may render contact mode laser lithotripsy problematic. For example, in a calyx the fiber might not orient at all to the stone surface.
