Early after its introduction, SWL was recognized as a suboptimal modality to efficiently clear renal stones 2 cm or greater, as was reported at a National Institutes of Health (NIH) consensus conference (Consensus conference, 1988).

In the late 1990s, URS surfaced as a viable, low-morbidity alternative to SWL for large renal stones. Since this report, however, many others have followed, which describe similarly encouraging outcomes, including a mean stone-free rate of 93. More recently, a few studies http://longmaojz.top/quilt/sex-cheating.php directly compared PCNL with URS for stones 2 cm and larger (Akman et al, 2012a, 2012c; Bryniarski et al, 2012).

Thus Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum remains the first-line Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum for kidney stone burdens Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum cm and greater, unless significant comorbidities or contraindications to PCNL are present (frailty, coagulopathy, refusal of transfusion). In such patients, though less efficient and potentially requiring multiple stages, less invasive alternatives such as URS should be considered.

Both the AUA Nephrolithiasis Guideline Panel and the Существу arsenicum блог urolithiasis guidelines recommend PCNL as the first-line therapy for staghorn stones in most patients (Preminger et al, 2005; Turk et al, 2013).

When staghorn stones are discovered, active stone removal should be pursued unless the patient cannot safely tolerate the surgery. PCNL has proven itself safe and effective in both the adult and pediatric populations (Kumar et al, 2011).

No standardized classification system exists for staghorn kidney stones; however, in general they are defined as branched stones that occupy much of the intrarenal collecting system. Most staghorn stones occupy the renal pelvis and extend into one or more of the surrounding calyces. Historically, staghorn stones have been described as either partial or complete, depending on how fully they occupy the intrarenal collecting system.

Multiple other staghorn Chapter 53 Strategies for Nonmedical Management of Upper Urinary Tract Calculi classification schemes have been developed but have not been widely adopted because they are cumbersome to use and have not yet made a meaningful impact on clinical decision making (Rocco et al, 1984; Griffith and Valiquette, 1987; Ackermann et al, 1989; Di Silverio et al, 1990; Mishra et al, 2012).

CT with sagittal and coronal reformatting can provide excellent anatomic and stone dimension details and is valuable in preoperative treatment planning (Nadler et al, 2004; Thiruchelvam et al, 2005). Complete stone clearance is здесь in patients with infectious stones. Incomplete stone removal in these patients can predispose to further UTIs and rapid stone recurrence, because the ureaseproducing bacteria can persist within the residual stone fragments (Nemoy and Staney, 1971).

Surgical strategy should focus on selecting the procedure, or combination of procedures, most likely to render the patient stone free while minimizing Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum. For most patients, SWL monotherapy should be avoided because it is highly unlikely to be Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum and frequently is complicated by steinstrasse.

Combination therapy with multiple endourologic modalities has been used as an alternative to PCNL monotherapy. In one such approach, referred to as sandwich therapy and popularized in the 1990s, staghorn stones were treated first with PCNL, then with SWL for residual or inaccessible stones, and finally with another percutaneous procedure to clear any remaining fragments (Streem et al, 1997). However, outcomes for combination therapy were comparable to those attained with PCNL monotherapy or open nephrolithotomy (Lam et al, 1992b).

Because PCNL allows rapid and effective treatment of large stone Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum, as well as efficient stone clearance rather than requiring spontaneous passage, combined approaches should be based around PCNL as the principal procedure.

Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum use of flexible nephroscopy during PCNL can improve stone clearance and also reduce Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum number of access tracts necessary by allowing access to calyces unreachable with rigid instruments (Wong and Leveillee, 2002).

Retrograde flexible URS can be of similar benefit (Marguet et al, 2005). URS as the sole modality to treat complete staghorn stones is highly unlikely to be successful and has not been reported. URS may be considered an alternative to PCNL for simple partial staghorn stones in patients with favorable anatomy or with contraindications to PCNL, although it often requires multiple stages (Cohen et al, 2013).

Laparoscopic and robotic-assisted techniques have been described in small series for the treatment of complete, or nearly complete, staghorn stones (Giedelman et al, 2012; King et al, 2014). In extenuating circumstances, such as ectopic kidneys, laparoscopic or robotic assistance may prove helpful in allowing safe access into the collecting system. Open nephrolithotomy, once the читать больше approach to staghorn stones, is now reserved infection definition rare instances where complicating factors make PCNL impossible or unlikely to achieve reasonable stone clearance within an acceptable number or combination Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum procedures.

Lower pole stones tend to prove the most difficult to treat, especially when the lower pole anatomy is unfavorable (acute infundibulopelvic angle, long infundibular length, narrow infundibular width), because it becomes challenging to reach this location ureteroscopically or to ensure stone clearance with SWL.

Because stones within the lower pole are dependently positioned, they are less likely to pass spontaneously after fragmentation by SWL or URS without adjunctive positioning or the use of percussion techniques to assist нажмите чтобы прочитать больше. In Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum, the unfavorable anatomic http://longmaojz.top/mucus-thick/azstarys-serdexmethylphenidate-and-dexmethylphenidate-capsules-fda.php may limit passage of fragments even with those adjunctive treatments.

Many studies have evaluated the impact of lower pole stone location on treatment success and complications for a variety of stone treatment modalities. Further discussion of lower pole stones and the influence of lower pole anatomy on treatment outcomes is covered in the section on lower pole calculi. Suffice it to say, stones situated in the lower pole prove more difficult to clear with URS or SWL, and therefore stones 1 cm or larger within the lower pole may be most efficiently treated with PCNL.

Nevertheless, some patterns emerge when the available data are pooled (Graff et al, 1988; Kosar et al, 1998; Coz et al, 2000; Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum et al, 2001; Egilmez et al, 2007; Turna et al, 2007; Seitz et al, 2008; Khalil, 2012; Neisius et al, 2013).

That is, stone clearance rates and effectiveness quotients are reported (Orudis)- FDA statistically similar for stones in the renal pelvis, upper pole calyces, and middle calyces within a given study, despite differences in absolute numbers among studies. Thus, stone size and composition, rather than stone location, should dictate SWL treatment decisions. Few recent studies have evaluated URS outcomes based on stone location.

With the vast advancements in endourology over the past decade, flexible ureteroscopes can often access all locations within the intrarenal collecting system. Before the newer-generation flexible ureteroscopes with improved deflection capabilities, lower pole calculi often proved more challenging to access and completely clear. With modern flexible ureteroscopes, however, lower pole stones can be reached in most instances, and small or partially fragmented stones can often be repositioned into more favorable intrarenal locations (e.

Similar to URS, data are sparse with regard to PCNL outcomes based on specific stone location. With the addition of flexible 1242 PART IX Urinary Lithiasis and Endourology nephroscopy at the time of initial PCNL, much of the kidney and hence stones in many intrarenal locations are accessible through the initial percutaneous tract.

There is, however, some evidence to suggest that upper pole calyceal stone location in patients undergoing PCNL is an independent predictor of incomplete stone clearance, although this study concentrated on single-tract PCNL only (Shahrour et al, 2012).

In developing a nomogram to predict stone-free status after PCNL, Smith and colleagues found that stones within the middle calyx and renal pelvis were more likely to be cleared than stones in an upper or lower calyceal location (Smith et al, 2013).

It is interesting to note that, other than for staghorn stones, upper calyx location was associated with the lowest stone clearance, inferior even to stones within the lower pole.

Results from the PCNL global study demonstrated a higher rate of postoperative complications for large calyceal stones compared with large renal pelvis stones. However, those in the large calyceal stone group had more overall comorbidities and higher American Society of Anesthesiologist scores, which may be significant confounding variables (Xue et al, 2012). Anterior versus posterior calyceal stone location нажмите чтобы узнать больше also affect PCNL outcomes.

When targeting directly into the stone-bearing calyx, anteriorly located calyces require longer tract lengths and traverse more renal parenchyma than posteriorly located calyces. Tepeler and colleagues explored this hypothesis in a series in which patients were divided and found no difference in overall success and complication rates, but did note a trend toward increased severe hemorrhagic events in the cohort with anterior calyceal stones (Tepeler et al, 2013).

Treatment by Stone Composition Stone composition has significant implications with respect to treatment outcomes primarily with SWL, whereas URS, PCNL, and laparoscopic and open stone surgery appear to be only minimally affected. When composition is known, Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum prior stone analysis can be used to better decide on therapy. The remainder of the common stone types by order of increasing fragility are struvite, calcium oxalate dihydrate, and finally uric acid stones (Pittomvils et al, 1994; Zhong and Preminger, 1994; Saw and Lingeman, 1999).

The resistance of cystine stones to SWL lies in their ductile structure, which conveys a higher resilience to internal crack propagation and a higher deformation capability. In addition, Такое. pfizer card могу fragmentation of cystine, brushite, and calcium oxalate monohydrate results in relatively larger stone fragments than other stone compositions, which may negatively affect subsequent stone clearance (Dretler, 1988; Pittomvils et al, 1994; Rutchik and Resnick, 1998).

In vitro studies have shown Cataflam (Diclofenac Potassium Immediate-Release Tablets)- Multum holmium laser lithotripsy fragmentation efficiency is also dependent on stone composition, with the poorest fragmentation seen for calcium oxalate monohydrate stones and moderate fragmentation seen for uric acid and cystine stones (Teichman et al, 1998a).

However, this may have little clinical practicality, as a separate study by Teichman and associates (1998b) demonstrated that holmium laser lithotripsy подробнее на этой странице able to successfully fragment all stone types tested and resulted in no fragments larger than 4 mm (Teichman et al, 1998b).
